best contemporary works. These errors are iusig-nificant in themselves, ex- 

 cept iu so far as they show the acquaintance of the author of a table with 

 the works of his predecessors, Shortredc was absent in India during the 

 publication of the 184-1 edition (which contains seven of these errors) ; but 

 that of 1849 was published under his own superintendence, and still it con- 

 tains six, while Ijabbage, Hulsse's Vega, and other works of earlier date 

 have but one. See ' Monthly Notices of the Eoy. Ast. Soc.,' March 1873, 

 t. xxxiii. p. 33-5; and Gernerth's tract (§3, art. 13, p. 55). 



Stansbury, 1822. [T. 1.] Small table to convert arc into time. 



[T. II.] Proportional logarithms for every second to 3°, to 4 places. Same 

 as T. 74 of Eapee. 



T. D. Log semitangcnts, viz. log — ^-^ from a:=0 to x= 180° at intervals 



of 15', to 3 places. This table occupies one page. 



T. G. Proportional logarithms for every minute to 24"', viz. log 1440 

 —log Xi the arguments being expressed iu houi'S and minutes (and also iu 

 arc), to 4 places. 



T. H. (pp. 215-304). Log sines and secants, also log versed and sucovcrsed, 



from 0° to 90° at intervals of 15" (arg-uments also expressed in time), to 5 places. 



By "versed" and "sucovcrsed" are meant " scmiverscd sine ''and "scraisu- 



coversed sine " (the terms introduced by De Mcndoza y Eios being used for 



1 -I- cos X 1 -l- sm X 

 brevity, see Rios, 1809); so that the table gives log ^ — and log — . 



This table was copied from T. XYI. of Eios ; but there is a difference of 

 arrangement, as the original table gave log sines, cosines, &c., the arrange- 

 ment being scmiquadrantal, while in the present work it is quadrantal. 



T. X. Pivc-figure logarithms from lOOU to 10,000 ; no differences. 



T. Y. Halves of natural sines, viz. | sin x from .r=0° to ar=90° at in- 

 tervals of a minute, to 5 places, with proportional parts for seconds. 



The other tables are nautical. 



Stegmann, 1855. T. I. Six-figure logarithms to 119, and five-figure 

 logarithms, with differences, from 1000 to 10,000. 



T. II. AntHogarithms from -0000 to -9999, to 5 j)laces. A few tables of 

 atomic weights &c. are added. As in Filipoavski's tables, the terminal 5 is 

 replaced by the Eoman V when it lias been increased. 



The preface to these tables is signed by Stegmann, but his name does not 

 appear on the titlepage. 



^Stegijaanu. This work we have not seen. Three errata in it are given 

 by Prof. Wackerbarth in. the 'Monthly Notices of the Eoyal Astronomical 

 Society ' for April 1867 : and this is the only place in which wo have seen 

 the table referred to. It is very possibly a five-figure hyperbolic logarithmic 

 table, similar to the same author's table of common logarithms just de- 

 scribed. 



Janet Taylor, 1833. T. XVII, Log sines, tangents, and secants to 

 every quarter point, to G places. 



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



T. XIX. Log sines and tangents for every 10" to 2°, and log sines, tan- 

 gents, and secants for every minute of tho quadrant, to 6 i)laccs, with dif- 

 ferences. 



T. XX. Natural sines for every mimite of the quadrant, to 6 places, 



T. XXI. Log versed sines to 8'' at intervals of 5**, to 5 places. 



T. XXXVI. Proportional logarithms for every second to 3°, to 4 places ; 

 same as T. 74 of Eapee. ■ . ■• . ■ -..-..
