THE EIiE3IENTS OF ECONOMICS. By Henry BrN^'lNG Macleod. 

 M. A., of Trinity College. Camhrid^e, and the Inner Temple, barrister-at- 

 law selected by the Royal Commissioners for the Digest of the Law to pre- 

 pare the digest of the law of bills of exchange, bank notes, etc.. Lecturer 

 on Political Economy in the University of Cambridge. In two volumes. 

 Volume I now ready. 12mo, cloth. Price, $1.75. 

 " Mr. Macleod's works on economic science have one great merit, they belong 

 to the class of books that assist inquiry by setting their readers thinking. The 

 views they set forth are not only often valuable in themselves, but they are the 

 generative cause of ideas which may also be valuable in their readers. His 

 books, moreover, are written in the proper way. The subject is divided care- 

 fully in accordance with the opinions held by tlic author ; all classifications when 

 made are adhered to, and the descriptions and definitions adojjted are admir.ible 

 from his point of view, and in some cases from a wider stand-point."— 7%«/S<a<i«<. 



ADOIiPH STRECKER'S SHORT TEXT-BOOK OF ORGANIC 

 CHTJMISTRY. By Dr. Johannes Wislicenus. Translated and edited, 

 with Extensive Additions, by W. H. Hodgkinson, PL. D., and A. J. Green- 

 away, P. I. C. Svo. Cloth, $5.00. 

 "Let no one suppose that in this 'short text-book' we have to deal with a 

 primer. Everything is comparative, and the term 'short' here has relation to 

 the enormous "development and extent of recent organic chemistry. This solid 

 and comprehensive volume is intended to represent the present condition of the 

 science in its main facts and leading principles, as demanded by the systematic 

 chemical student. We have here, probably, the best extant text-book of organic 

 chemistry. Not only is it full and comprehensive and remarkably clear and 

 methodical, but it is up to the very latest moment, and it has been, moreover, 

 prepared in a way to secure the greatest excellences in such a treatise." — The 

 Popular Science Monthly.
