' Babbage's Table of the Logarithms is the best for ordinary use. Great i!ains were taken to get the niaximnni of clearness. 

 Tlie change of figure in the middle of the block of numbers is marked by a change of type in the fourth ligure, wliieh is the 

 be.st method that has been used. Copies of the book were printed on pai>er of ditlerent colours— yellow, bnnvn, green, 

 etc.- as it was considered that black on a white ground was a fatiguing combination for tl;e eye.'— J. Jr. /.. Gl(ii.-h> r, I'. U.S.

Contract by Messrs. Sotheby, Wilkinson <& Hodj^e, 8vo. sewn (scarce), 10* 6d 1872 



This excellent collection, i^erhaps one of the most valuable and representative scientific libraries ever collected within 

 recent times, consisted of 2'>90 lots distributed as follows :— Pure Mathematics, T'.'O ; As'ronniiiy, 454; Mechanics and 

 Acoustics, 267 ; Optics, 182; Electricity and Magnetism, l-*! ; Meteorology, 11; Tabhs, ■2<;-, ; Ti uVvietions of Scientific 

 Societies, 101 ; Miscellaneous (including History, Biogra]>hy, etc.), 3i:7. 



Owing to the unmerited neglect whicii books of this character have constantly received, not only from the book-collector 

 but als«"> from the bibliograi>her, the above catalogue is of no little bibliographical value.
