"It is difficult to prai=e too highly the selection of materials and their arrangement, or the 

 wealth of illustrations which explain and adorn the text. Whatever tests of accuracy as to figures 

 and facts we have been able to apply have been satisfactorily met, while in clearness of statement 

 this third volume leaves nothing to be desired." London Academy.

"Mr. Maeleod's works on economic science bave one great merit, they belong to the class of 

 books that assist inquiry by setting their readers thinking. The views they set forth are net only 

 often valuable in themselves, but they are the generative cause of ideas which may also be valu- 

 able in their readers. His books, moreover, are written in the proper way. The subject is divided 

 carefully in accordance with the opinions held by the author; all classifications when made are 

 adhered to, and the descriptions and definitions adopted are admirable from his point of view, and 

 in some cases from a wider 6taud-point." The Statist.

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

 thing 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 repre- 

 sent the pre-ent condition of the science in it main facts and leading principles, as demanded by 

 the systematic chemical student. We have here, probably, the best extant textbook 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.
