 G., Professor of Theory and Practice of Pharmacy in the Philadelphia Col- 

 lege of Pharmacy, Vice-Chairman of the Committee of Revision and Pub- 

 lication of the United States Pharmacopoeia; Samuel P. Sadtler, F. C. S.,

 $8.00. 



This work is now in its fifteenth edition, and for over half a 

 century has been found wherever the English language is read. 

 The revision has occupied most of the spare time of the editors for 

 three years, and as a result we have a large amount of new matter. 

 In the present index there are more than 16,000 titles, an increase 

 over the last edition of nearly fifty per cent. In completeness it 

 stands unrivaled in its line, and in accuracy it has no superior. The 

 apothecary, the physician and the chemist can feel secure best when 

 provided with a copy. The book is well known and needs no 

 recommendation to insure a large sale. 



Bacteria and the Germ Theory of Disease. By H. Gradle, M. D., Pro- 

 fessor of Physiology, Chicago Medical College. Large Svo. ; pp. 219. 

 Price, $2.00. W. T. Keener, 96 Washington Street, Chicago. 1883. 



This is an exceedingly interesting work of eight chapters. It 

 comprises eight lectures given by Prof. Gradle before the students 

 of the Chicago Medical College this past winter. The first lecture 

 considers many diseases as a struggle between the animal system 

 and the parasites invading it; the false doctrine of spontaneous 

 generation, and the classification of bacteria. The classification 

 adopted is that of Cohn. Lecture second gives the staining methods, 

 the structure of bacteria, their composition, food, vitality, etc. Then 

 follows a discussion of the various surgical infections due to bac- 

 teria, pyaemia, furuncles, erysipelas, etc.; also various diseases, as 

 measles, small-pox, malaria, pneumonia, etc. We could quote page 

 after page of this work that would be of interest to our readers, but 

 we heartily commend the work and add that you can easily read all 

 that is in it for the small price of $2.00.
