 " Mr. Macleod^s works on economic science have one great merit, they l)elong 

 to the class of books that aseiet 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 tbeir readers. His 

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

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

 made are adhered to, and the descriptions and dcHnltions adopted are admirable 

 from his point of view, and in some cases from a wider stand-point."— ?%« StaHet. 



ADOIiPH STRECKER'S SHORT TEXT-BOOK OP ORGANIC

**Let ro 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 pTinciples, as demanded by the syBtematic 



chsmlcal 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 



Fopular Science Monthly.
