✦ Synopsis


In nmking a careful comparison between the last (the 22d) edition, and the one that precedes it, the expert cannot fail to be struck with the great improvement exhibited by the present edition. We say improvement, although it seemed ahnost impossible that the book in its various editions needed any other than, perhaps, such as related to minor details only, and such additions as were needed from time to time in bringing the book down to date. The value of Mr. Trautwine's book has best proved itself by the fact that perhaps seventy-five per cent. of all of those who have occasion to use such a work of reference, prefer it to-day to any other. This is no doubt directly due to the practical and common-sense manner in which Mr. Trautwine treats the subject-nmtter.
