The title page includes this epigram —
frustra fit per plura, quod fieri potest per pauciora
evidently from Aristotle (and associated with Occam’s Razor), that Englished signifies
It is vain to do with more, what can be done with less.
This volume includes a
specimen of the Telegraphic Dictionary, pp67-77, covering 999 terms, and of a second vocabulary consisting of expressions, not found in the former dictionary, now arranged in
classes each able to total 999 words. Macdonald’s 1817 code vastly expands these vocabularies.
Contemporary and later treatments of Macdonald’s code are dismissive and even derisory, focusing on his shutter and other mechanical devices. This is unfortunate, because Macdonald’s more interesting work is found in his vocabularies, projected in this 1808 volume, and achieved in his 1817 Treatise Explanatory. He needs to decide what expressions to leave out, and what to retain, and in what arrangement. The Treatise presents his thinking at the time of writing.
Reserving fully as much as might be necessary for naval, military, political, and commercial uses, a numerous list of words may
be rejected, as quite unnecessary to be inserted in the Dictionary; such as, technical, biblical, philosophical, legal, logical, philological, botanical, anatomical, zoological, chemical, magnetic, pneumatic, musical, optical, architectural, mathematical, agricultural, and all abstract words of erudite signification. A great number of compound verbs, such as to unchurch, to refrigerate, to obtemperate, to decorticate, to decompound, &c. &c. may be omitted. Such verbs as, to attinge, to boll, to brutify, to dehort, to enucleate, to gloze, to fizzle, to gaunch, to fudge, to unboy, to twattle, to refel, to king, &c. &c. will be useless. A large proportion of adjectives may be rejected, as ambidexter, apocryphal, boreal, debonaire, festivous, evened, facinorous, flavourous, laniginous, latrant, pharisaical, patronymical, and so on. There is a multiplicity of substantives of little or no use in, the English language, such as, ambitude, arcuation, boutefeu, expugnation, foison, infendation, occursion, parasang, and such like. The words in a common pocket Dictionary amount to about 28,000. Those in the single volume larger Dictionary may be about 60,000. All the words in the English language may amount to 70,000, or more. By rejecting all words quite unadapted to Telegraphic purposes, the number wanted might conveniently be reduced to 40,000. It is proposed, for reasons which will be stated under the description of the improved Telegraph, to divide these into Classes of 999 words in each Class. The words in each class are numbered, near the margin, from 1 to 999, inclusive. The number of each class, as class 1, or class 20, &c. is put at the top of the page, where the letters indicating the words under them, are printed, as usual.
This is followed by a discussion of how inflections are to be treated, and then another of specialized
At the end of the Telegraphic Dictionary, a few useful Classes will be added. The Navy, alphabetically arranged, will constitute a Class. The Admirals, Captains, Commanders, Lieutenants, Pursers, and Surgeons, will form probably three Classes of 999 names in each Class. The names of the Officers of Marines, alphabetically arranged, will form a Class. Field-Marshals, Generals, Lieutenant-Generals, Major-Generals, Colonels, Lieutenant-Colonels, and Majors in the army, will be alphabetically disposed of in, probably, two Classes. Artillery and Engineer officers, as far as Captains, will form a Class. As casualties are liable to take place in these last four Classes, the sheets containing them may, annually, if necessary, be corrected, and easily replaced in the Dictionary. The names of oceans, seas, channels, harbours, bays, sea-ports, gulphs, islands, capes, streights, promontories, quarters of the world, remarkable sand-banks, navigable rivers, clusters of islands, anchorages, and rocks, will be alphabetically inserted in a very useful Class. Kingdoms, continents, provinces, states, counties, shires, departments, rivers, mountains, lakes, locks, passes, bridges, capital towns, towns, cities, duchies, fortresses, military or naval depots, and peoples, will afford, probably, two Classes alphabetically drawn up; and like all the others, regularly numbered. There should be two Classes, giving the Marine terms and expressions, in alphabetical order. Christian names of men, will form a short Class. The usual naval movements, manoeuvres, and procedures, are condensed into about six hundred sentences. When any one of these sentences is to be referred to, its number is signalled by means of Flags, as will be hereafter explained, in treating of naval signals. These sentences, and as many as will make up 999, will be inserted in a Class at the end of the Dictionary. A Class of sentences indicating military movements, and Field-procedure, may be found convenient. The vast number of words which can be rejected, will make ample room for the provision made for introducing the inflexions of verbs, the plurals of nouns, and the Comparatives and Superlatives of adjectives. When all the useful Classes mentioned, are added to the Telegraphic Dictionary, it will still be of a very portable size.

As its title indicates, this volume contains two separate works, a treatise, and the dictionary. Each has its own title page —
|Title pages of John Macdonald, Treatise Explanatory (1817) and A Naval, Military and Political Telegraphic Dictionary (1817), in same volume.|
Scire tuum nihil est, nisi te scire hoc, sciat alter. — Pers. Sat.
from Aulus Persius Flaccus (34-62), a Roman satirical poet and moralist, Satire I, line 26.
Usque adeone scire tuum nihil est, nisi te scire hoc sciat alter? :
Is all your knowledge to go so utterly for nothing unless other people know that you possess it?
Frustra sit per plura, quae fieri potest per pauciora
Found in many 19c compilations, evidently related to Occam’s Razor:
It is vain to employ many means, when fewer are enough.
Macdonald’s systems were subject to criticism for being cumbersome; his
anthropo-telegraph involving five men holding flags, their actions guided by a sixth
director comes in for special derision by H. P. Mead in his
The Story of the Semaphore (Mariner’s Mirror 19 (January 1933). See also David Lyndon Woods, The Evolution of Visual Signals on Land and Sea (dissertation, Ohio State University, 1976): 49. Macdonald’s signal system may have been flawed, and his vocabulary unnecessarily large for nautical purposes. But his vocabulary is quite interesting.
|Two pages from Class XII (they-thing-thirdly) ex John Macdonald, A Naval, Military and Political Telegraphic Dictionary (1817)|
Macdonald arranges his vocabulary in 99 + 42 different classes (numbered 1-99, X-XL, XL-LII), each containing up to 999 instances (141 x 999 = 140,859 terms). The vocabulary contains single words and (many more) phrases; he discusses the compilation in his introduction:
It appeared a defect of the two former Dictionaries [Macdonald’s own], that frequently occuring words, such as why, where, with, if, &c., &c. were not combined, so as to form adjunct current phrases. This has been effected in the instances of such words as are printed at the tops of the columns: and these various instances are, frequently, between two and three thousand. In doing this, it became necessary to compare such words with every word in a common Dictionary, selecting such combinations as struck the mind’s eye to be of common recurrence and use. This consideration alone will enable any person to judge of the labour it required to compose the Telegraphic Dictionary. (p9, here)
Much of Macdonald’s prefatory discussion is devoted to signals, whether land or sea. While these are of enormous practical significance, my own interest — here as elsewhere in this project — lies rather in the phrases themselves, their selection and their organization in the code book. The main phrase vocabulary contained in 99 + 11 classes (through XL 118) is followed by several appendixes (classes XL through LII), providing certain special and technical terms. Those are listed below.
- Christian names of men, alphabetically arranged; Names of women; Latin and French Phrases; Titles, and days of the months; Days of months, and remarkable days

Should the attack of the first line fail, it will retire through the second line, and the reserve, the cavalry covering the movement. The second line will advance to meet the first. When near the first, it will halt, and dress, as well as circumstances will admit of, previously, to moving on to the attack after the first line has passed through it. 94

These would seem to be specimens, as if a prospectus.
Macdonald’s systems — both mechanical and lexicographic — were dismissed for being cumbersome. His
anthropo-telegraph involving five men holding flags, their actions guided by a sixth
director comes in for special derision by H. P. Mead in his
The Story of the Semaphore (Mariner’s Mirror 19 (January 1933). See also David Lyndon Woods, his very useful The Evolution of Visual Signals on Land and Sea (dissertation, Ohio State University, 1976): 49.
Geoffrey Wilson in The Old Telegraphs (1976) describes Macdonald (perhaps accurately) as an
eccentric bore who was obsessed with complication. He dismisses Macdonald for his long preference for the shutter method and to coding versus spelling —
Macdonald remained obstinately convinced that a shutter was better than a semaphore and numbered sentences better than spelling.
Wilson proceeds then to the dictionary :
Macdonald’s Dictionary (1817) ran to hundreds of pages. Unlike an ordinary lexicon it contained thousands of phrases of which some might occur once or twice in a lifetime. For instance, there are 1,500 expressions under
great absurdity to
great wrong and including
great rascals and
great rhapsody of nonsense! Each would need at least five variations of aspect. If only one in five were corrupt, the received might well take in
great nourishment instead of
Macdonald’s signalling system(s) — and the attendent classes and 1-999 phrases for each — may have been deficient. Yet it followed from his two objectives: (1) anticipation of any likely utterance in the phrase vocabulary
as struck the mind’s eye to be of common recurrence and use, and (2), the ability to reduce the number of signals needed for the transmission of a message (to save movements), by increasing the size of the vocabulary. His Telegraphic Vocabulary anticipates the so-called verbatim codes, including Frederic G McCutcheon his enormous International Banking Corporation Telegraph Code / Phrase Tables of 1908; its emphasis on actually used phrase chunks (as judged by Macdonald), rather than fully complete sentences, seems to me pertinent to much later schemes for machine translation, involving chunks extracted from text corpora.
Thus, it was a remarkable effort at language engineering by a figure who was, ultimately, an engineer. And for this reader, its repetitions and variations make it a beautiful achivement of lexical and poetical art.
John Macdonald (1759-1831). His mother Flora Macdonald (1722-1790 *) was the well-known
Jacobite heroine, writes Alan Harfield in the current edition of the Oxford Dictionary of National Biography; see also the entry in the Dictionary of National Biography, vol 35 (1893) here. His military career spanned the years 1780-1806, largely with the East India Company in India and West Sumatra (Bencoolen), involving various surveying and engineering work, and experimentation with fuses.
He was better known as a military engineer and cartographer, and for his writing on subjects other than his code, including the violincello. I have been dilatory about developing a separate page to devoted to this man, whose interests were many, and whose energy was enormous.

The Introduction explains the incorporation of
Mr. Walker’s stereotypedCritical Pronouncing Dictionary at pp xxvii-xxxi, starting here. The basic idea is to indicate
Walkerwith a D (for
Dictionary) pennant, followed by indicators for page and word-number, respectively.
The examples he shows do not exactly match page number, nor even location of folios, of editions available online, but this American edition published in 1818 serves well enough. Lynn’s usage of Walker is presented as a temporary expedient: he has been called to sea again, he writes, so that publication of his work in a complete state, including
a simple system of signifying all the words of the English Dictionary,must await another time. (pp x and xxvii).

This book is interesting largely for the arrangement of its phrase matter. Lynn (1774-1847) was a commander of the East India Company and author of Nautical and Astronomical Tables (1825), Horary Tables for Finding Time by Inspection (1827) and other works, hints of which can be found in the contents of the telegraphic code described here. He was also one of the authors of An Historical and Descriptive Account of China (Edinburgh, 1836), his contribution being a chapter on navigation to China.
Lynn is briefly described at the online pages to The Skilfull Seaman,
An exhibition of items from the Foyle Special Collections Library to mark the 200th anniversary of the Battle of Trafalgar (notes to Case 5). There is an entry on Lynn in the DNB.

The Committee for managing the affairs of Lloyd’s having been informed by the Committee of the Society of Ship Owners, that they have determined to supply the Masters of their ships with a Code of Signals, which has been compiled and published by Capt. Frederick Marryat, R. N. for the use of Vessels employed in the Merchant Service, and to recommend it for general adoption; the Committee consider it incumbent on them to furnish the Agents to Lloyd’s with Captain Marryat’s publication, in order that they may be enabled to understand Signals made by Vessels using this Code.
I am, therefore, directed to send you a copy of the same, and to request your particular attention when Signals are made; the Committee being of opinion that they may, in cases of accident, be the means of Vessels obtaining such assistance from the shore as is likely not only to tend to their safety, but, in the event of Shipwreck, to the preservation of their Crews.

It may be proper to add, that the Geographical Table and Ships’ Names are not filled out, as they would be those in use at any given time.
The preface is basically a complaint, at Raper’s submission to the Admiralty being either unnoticed or, later, likely to be used (along with other codes) as source of a new code. and so he obtained a patent. The volume lists several errata at end; two (or more) errata/augmentations are distributed elsewhere. The TOC does not accurately reflect contents (at least for start of preface).

The correct meaning of the signals taken from the Compound Table will always be given in the sentence that precedes it. Some later telegraphic codes employed variations of this technique. Here is the salient passage from the
This Table is composed of such objects of inquiry and conversation at sea, as generally require to be formed into so many different tables, with each its proper distinguishing signal; such as points of compass, date of the month, day of the week, hour of the day, degrees of latitude and longitude, names of harbours, towns, headlands, &c. The bringing of this heterogeneous matter together into one table, is founded upon the supposition, that a preceding sentence clearly shows the column of the Compound Table to which the signal made refers, or in which the answer to be given must be sought for. And though the signals for this table are the same which are used to express sentences, yet no mistake can happen, as it will always be clear from a preceding signal, whether the signal following, or the answer required, is to be looked for in the Compound Table, or not.
Here are sentences taken from Chapter 15 in the

Note to the Eleventh Edition :
With the view of rendering this Code of Signals as complete and as perfect as possible, there has been added to the present Edition a plate of the Mercantile Flags of those nations whose Merchant Vessels are more frequently met with at sea; the list of Lighthouses has not only been much enlarged in number, but for the first time it has been rendered still more serviceable by the addition of the description of light, whether fixed or revolving, its latitude and longitude, and the number of miles at which it is visible; and to afford greater facility in reference, the Sentences have been further extended by reduplication.

It was only in 1884 that the International Meridian Conference adopted the Greenwich meridian as the universal Prime Meridian or zero point of longitude. *. Before then, maritime states reckoned longitude from different meridians (generally being their capital city). The Companion enables users of different nations, each with their respective meridians (Greenwich, Amsterdam, Cadiz and Paris), to encode their, and decode others’, longitudes with ease and absence of error. As its preface explains —
It therefore becomes necessary, when the longitude is signalized by a British, French, Dutch, or Spanish ship, to add or subtract to or from places, the adopted meridians of which are east or west of each other.
In the tables, Part II., the longitudes will be found assimilated in every case, so that no more is necessary than to ascertain the nationality of the vessel making her longitude known by signal, or otherwise, and to compare it with the longitude reckoned from the meridian adopted by the observer, to arrive at the same position on the chart.
Observations on signalizing are detailed at pp vii-viii, and provided in abbreviated fashion, in seven languages, at pp 9-11. In English, they run thus:
Directions for exhibiting and deciphering the signals.
These Intimations of Reckoning are distinguished from other Signals, because a Ball always forms part of the hoist.
The National Ensign must be shown when making a Signal.
Any Latitude is signalized in Degrees and Minutes by hoisting the Flags representing the Letters placed against it in Tables Part I., with the ball between the Flags, see Examples 1, 2,3, and 4.
Any Longitude is signalized in like manner, the Ball being over or under the Flags, see Examples 5, 6, 7, and 8.
The Ensign denotes what Meridian is used; and in Part II., against the Longitude signalized, will be found the Longitude of other Meridians, all of which describe the same place on the Chart.

Title: CONVICT DEPARTMENT
Start Date: 01 Jan 1818
End Date: 31 Dec 1877
The Convict Department was part of the Imperial (as distinct from Colonial) establishment and was directly responsible to the Governor. By 1871 the number of Imperial convict (or ex-convicts in lunatic asylums) was so few that they were transferred to colonial custody, though their costs continued to be met out of Imperial funds.
