APPENDIX.


In the preparation of the foregoing Catalogue, several works by other Authors were met with which have considerable interest from their connection with the works of Napier. It seemed desirable to preserve a record of them, and they are accordingly given below, with such particulars as were noted at the time.

Napiers| Narration:|Or,|An Epitome|Of|His Booke On The|Revelation.|Wherein are divers Misteries disclosed,|touching the foure Beasts, seven Vials, seven Trumpets,|seven Thunders, and seven Angels, as also a discovery of|Antichrist: together with very probable conjectures|touching the the time of his destruction, and|the end of the World.|A Subject very seasonable for these last Times.|

From the title-page it would appear that a previous edition had been published at Rouen. The work is written to confute Napier’s interpretation of the Apocalypse, and commences thus:—

Depvis quatre ou cing ans, a esté veu vn liure intitulé, L’ouuerture de l’Apocalypse, mis en lumiere par Napeyr Escossois, duquel n’ay voulu publier les erreurs, aduerty que ses partisans mesme le desauouēt, cōme plein de mensonges & impostures......

Johann Wolther, the Pastor of Liechtenhagen, was a zealous Lutheran, and adherent of the Augsburg Confession. In his work he reprints in full the 36 propositions of Napier’s First treatise as given in the Frankfurt edition of 1615, pp. 1–122, omitting the ‘Beschluz,’ p. 123. To each proposition is appended a refutation of the same. These refutations, being much longer than the propositions, form the bulk of the book.

In describing the formation of the Logarithmic Table, in section 59 of the Constructio, Napier says that Reinhold’s common table of sines (or any other more exact) will supply the values for filling in the natural sines in columns 2 and 6, and the table of sines in this work (“Canon Sinvvm Vel Semissivm Rectarvm In Circvlo Svbtensarvm.”, fol 114), was probably the one he made use of.

The second and third books of the Trigonometria deal with the subjects treated of in Napier’s Descriptio and Constructio, these works being largely made use of by Ursinus, who speaks of Napier as a Mathematician without equal (see p. 131, l. 5). The references in the text are to the Lyons edition of 1620 (see p. 178).

The Magnus Canon contains the logarithms of sines for every 10″ in the quadrant. They are arranged in a similar way, and are of the same kind as those in Napier’s Canon of 1614; but are carried one place ​

The methods employed are the same as those laid down in the Constructio with the modifications in regard to the preliminary tables proposed by Napier in sect. 60.

In this work the logarithms of the Magnus Canon of Ursinus are reprinted to every 10 seconds in the case of the first four and last four degrees, being the same as in the original. The logarithms from 4° to 86° are given for every minute only. Ursinus’ logarithms occupy half the lower portion of pp. 2–261 in Volume II., the title of the whole contents of these pages being:—

​German mathematicians, as he mentions in his Preface, not being satisfied with Napier’s demonstration based on Arithmetical and Geometrical motion. The two parts together with the Table are reprinted in ‘Scriptores Logarithmici,’ vol. I. p. 1. At the beginning of the same volume is reprinted the Introduction to Hutton’s Mathematical Tables, on p. liii of which will be found a “brief translation of both parts, omitting only the demonstrations of the propositions, and some rather long illustrations of them.”

The logarithms in the Table are of the same kind as Napier’s, but they are not affected by the mistake in the computation of the Canon of 1614.

The Tables of Kepler and Napier are differently arranged, and the numbers for which the logarithms are given are also different. In Napier’s Canon the numbers in column “Sinus” are the values of sines of equidifferent arcs, while in this table the numbers or sines are equidifferent. For specimen page of the Table see preceding page. The arrangement is as follows:—

Column 2 contains 1000 equidifferent numbers, 10,000, 20,000, 30,000, … 9,980,000, 9,990,000, 10,000,000. It also has at the beginning the 36 numbers 1, 2, 3, to 9; 10, 20, 30 to 90}; 100, 200 to 900; and 1000, 2000 to 9000.

Column 4 contains the logarithms of the numbers in column 2, with interscript differences.

The 2nd and 4th are the only columns containing entries for the first 36 numbers.

It will be observed that a point marks off the last two figures of the values in these two columns, but if it be left out of account the numbers and logarithms agree with those of the Canon of 1614, in being referred to a radius of 10,000,000. So that the values really represented are the ratios of the numbers there given to 10,000,000.

Taking as an example the first entry in the specimen page, the number in column 2 which is 4,850,000 represents the ratio 4,850,000 to 10,000,000 or a 4840000/10000000th = a 485/1000th part of radius. Similarly column 1 gives the arc, in degrees, minutes, and seconds, corresponding to a sine equal to the 485/1000th part of the radius, with interscript differences;

Column 3 gives in hours, minutes, and seconds the 485/1000th part of a day of 24 hours; and finally

​Column 5 gives in minutes and seconds the 485/1000th part of a degree of 60 minutes.

8°, 16 pages.

The above short Preface occupies the first page of a small tract of sixteen pages, the remaining fifteen containing the natural numbers from 1 to 1000 with their logarithms, to base 10, to 14 places. The tract bears no author’s name or place or date of publication, but the evidence which assigns it to Briggs, and fixes the place and date of its publication as, London, 1617, seems conclusive. The Table of Logarithms is the first published to a base different from that employed by Napier.

It is unnecessary here to refer to subsequent works on Logarithms of a different kind from those originally published by Napier.

Note.—In the foregoing Catalogue the only collections of Napier’s works referred to are in public libraries. The largest single collection, however, is that in possession of Lord Napier and Ettrick. Besides the editions more commonly met with, it embraces several not found in any of the public libraries of this country, as well as a copy of the rare ‘Ephemeris Motuum Celestium ad annum 1620,’ which contains Kepler’s letter of dedication to Napier, dated 27th July 1619.
