. 201 - - FOURTH IMPRESSION, roy. Svo. hf. roan, 5s 1844 



' Babbage's Table of the Logarithms is the best for ordinary use. Great pains were taken to get the maximum of clearness. 

 The change of figure in the middle of the block of numbers is marked by a change of type in the fourth figure, which is the 

 best method that has been used. Copies of the book were printed on paper of different colours yellow, brown, greon, 

 etc.- as it was considered that black on a white ground was a fatiguing combination for the eye.'/. W. L. Glaisher, F.R.S.
