2i8 THE JOURNAL OF PHARMACOLOGY. 



In this the last two lieferungen Belladonna, root and leaf, Cubebs, Stro- 

 phanthus, Kola and Aspidium are considered. Certain addenda are in- 

 cluded and a complete index of the whole work. It will remain a classic 

 for years. 



While Koch's work on the microscopical analysis of drug powders will 

 prove very interesting and suggestive we do not believe it can ever occupy 

 the high place taken by Tschirch's "Atlas." 



The author purposes publishing a complete list of powdered drugs, illus- 

 trated with full-sized plates, three quarto parts have now been issued. 

 After a general introduction of the methods of analysis of powders, mode 

 of examination and preparation, reagents, etc., the characteristics of bark 

 are taken up in much detail and there then follow a series of analytical 

 tables in which a number of powdered drugs are distinguished. There are 

 considered in the first volume. Cortex atiranti, Cascarilla and Cinchona 

 rubra. The descriptive text is almost too complicated for use — the ana- 

 lytical keys being somewhat cumbersome. The illustrations are excellent 

 and taken as a whole the book is a splendid addition to our literature on 

 the subject. 



O' i^>.li:*mper's second edition it may be said that it is rewritten and en- 

 larged and is one of the very best of the shorter descriptive works on the 

 microscopical examination of the vegetable foods, spices, etc. We com- 

 mend it heartily even to those of our readers who may have the first 

 edition. 



Hanausek's Text-book is entitled to more than passing mention. Since 

 the appearance of Wiesner's "Introduction to Technical Microscopy," 

 published in 1867, no complete work of the kind has appeared. If we ex- 

 cept Carpenter's work on the " Microscope," which is a much more heter- 

 ogeneous piece of work, there is nothing in the literature of anj' country 

 that so adequately fills the gap as this present work of Hanausek's. It is 

 an Index reruni of the natural products used in technical manufactures and 

 merits a wide distribution. 



Wiesner's Rohstofife has been a classical work of reference for so many 

 3'ears that the younger generation of workers are to be congratulated on 

 having such an excellent work brought up to date. It has been entirely 

 rewritten and fully illustrated. Such a work should have been in English 

 form years ago. It is to be hoped that the public demand for it would 

 stimulate the wary publisher into putting it into English dress.
