Dr. Stickler then gave a list of the different bacteria which had been 

 found in pus. It included : 



1. A streptococcus (in pus from acute abscesses, which, upon inocu- 

 lation, will cause the death of lower animals in from two to ten days). 



2. Micrococcus pyogenus aureus found in pus from puerperal fever, 

 boils, osteo-myelitis, etc., and is very poisonous. 



3. Strephalococcus, not as poisonous as the last. 



4. Bacillus of fetid pus ; very poisonous. 



Following the paper a specimen of urine from a patient suffering 

 with cystitis, was exhibited by Dr. Runyon, and the pus cells examined.

 Introduction by Prof. J. W. Spencer. The Humboldt Publishing 

 Co., 28 Lafayette Place, New York. 



The rapid progress of the science of Geology at the present day justi- 

 fies the reproduction of this series of papers contributed at various times 

 by the distinguished writers whose names are given. No one desirous 

 of being well-informed can afford to neglect this important study of 

 Geology, which many scientists claim disproves the Mosaic cosmog- 

 ony. The present work is in two parts, a double number and a single 

 number. (Price for both, 45 cents.) 



Chemical Reagents and Spectroscope. By Chas. O. Curtman, M. D.

It was to obviate the difficulty experienced by all engaged in analyt- 

 ical work of obtaining some of the rarer reagents, or in procuring those 

 on the market of the necessary degree of purity, that prompted Dr. 

 Curtman to compile the present volume. This book, as the author 

 says, is not intended to be a guide to analysis, or to compete in any 

 way with the standard works upon the subject, but rather to serve as a 

 supplement to them to aid the analyst in selecting, testing, and prepar- 

 ing the reagents he needs, and to gather into a single volume informa- 

 tion now scattered over a vast extent of chemical literature. 



In most cases the tests for the absence of all impurities are given, and 

 from these may easily be selected only those which are essential to a 

 special purpose, as it rarely happens that absolutely pure reagents are 

 necessary ; generally it is the absence of certain impurities only that is 

 required to render the reagent serviceable. The arrangement of the
