116 UEPoiiT— 1873. 



On pp. 591, 592, T. XIX. of Dodson's ' Calculator,' 1747 (viz. square and 

 cube roots of numbers less than 180, to 6 places), is reprinted ; and on pp. 

 .595-004 are reciprocals (to 9 places) and square roots (to 10 places) of 

 numbers from 1 to 1000, reprinted (as Maseres states in the preface) from 

 vol. iv. of Button's 'Miscellanea Mathematica ' (1775, 4 vols. 12mo). 



Maskelyne (Requisite Tables), 1802. T. XV. Proportional logarithms 

 for every second to 3°, to 4 places ; same as T. 74 of Rapek. 



T. XVI. For computing the latitude of a ship at sea, &e. The ai-guments run 

 from 0'" to 6'' at intervals of 10''; and there are three columns of tabular results 

 headed Log i Elap. time. Log Mid. time, Log rising, which give respectively 

 log cosec .r, log (2 sin a-), and log vers sin .r, to 5 places ; the lor/ rising is 

 also continued for arguments from 6** to 9'' at the same intervals. This table, 

 modified in form &:c., is reproduced in Mackat, Domke, &c. (see § 3, art. 15, 

 p. 68, and Boavdixch, 1802), and is sometimes called by Maskelyne's name. 

 T. XVII. Natural sines to every minute of the quadrant, to 5 places, 

 T. XVIII. Five-figure logarithms of numbers to 10,000. 

 T. XIX. Log sines, secants, and tangents to every minute of the qua- 

 drant, to 5 places; the sines are given to 6 places, the last being separated 

 from the rest by a point ; the other tables are nautical. 



Maskelyne's name does not appear on the titlepago to these tables ; but 

 the preface is signed by him. 



Appendix to the Third Edition. T. I. Natural sines to every mimite 

 of the quadrant, with proportional parts for seconds. 



T. II. Natural versed sines for every minute to 1 20°, with proportional 

 parts for seconds. 



T. III. Logarithms of numbers to 1000, arranged consecutively, and 

 printed in groups of five; and thence to 100,000 grouped in decades, with 

 proportional parts for each decade by its side. All the tables in the Appen- 

 dix are to six places. Copies of the Appendix were circulated separately. 



Minsinger, 1845. [T. I.] Seven-figure logarithms to 100 and from 

 1000 to 10,000, with proportional parts at the foot of the page ; the sixth 

 place is separated by a comma from the seventh, for convenience if the table 

 is to be iLsed to six places. The change in the lino is denoted by an asterisk 

 attached to all the logarithms affected. 



[T. II.] S(piares, cubes, and square and cube roots (to 6 places) of all 

 numbers from 1 to 100, and squares and cubes only of numbers from 100 to 

 1000. Then follow a few constants and [T. IV."] primes to 1000. 



Moore, Sir Jonas, 1G81. [T. I.] Seven- figure logarithms to 10,000 

 (arranged as is now usual), Avith diftereuces : the proportional parts [T. II.] 

 are given by themselves at the end, and occupy 22 pp. This may bo regarded 

 as a separate table, containing proportional parts (to tenths) of numbers 

 from 44 to 4320— the interval being 2 to 900, 3 to 999, 4 to 1415, 5 to 2000, 

 and 10 to 4320. 



[T. III.] Natural and log sines, tangents, and secants to every minute of 

 the quadrant, to 7 places (scmiquadrantally arranged), without differences. 

 It may be remarked that many of the N's at the top of the columns are 

 imperfectly printed, and appear like V's ; thus N. tangent is often printed 

 V. tangent, 



[T. ly.] (pp. 202-351). Natural and log versed sines from 0° to 00° to 



every minute, to 7 places. De Morgan says that this is the first appearance of 



this table in England. The other tables relate to navigation, geography, itc. 



[Moore, Sir Jonas, 1681] (Versed sines). Natural and log versed sines 



to every minute of the quadrant, to 7 places, scmiquadrantally arranged.
