SUMMARY OF CURRENT RESEARCHES RELATING TO 



growth was scanty and the medium was not liquefied. On egg-yelk and 

 blood the growth was very good, but the bacilli were very short and re- 

 sembled diplococci. On other media the bacilli were like those found 

 in the living body, beiug slightly bent, one end often thicker than the 

 other, and undoubtedly motile. 



Medium for Isolating Bacillus Typhosus in presence of Bacillus 

 coli communis.* — E. Cambier uses a freshly made bouillon prepared by 

 mixing cold 50 ccm. of a 3 p.c. pepton solution, 4-6 ccm. of 1 p.c. soda, and 

 4-6 ccm. of sea salt, all sterilised at 115°. With this nutrient medium 

 and the bougie method he has been able to isolate in pure culture the 

 typhoid bacillus from a liquid consisting of equal parts of coli and 

 typhoid bouillon cultures, and under even more difficult conditions. 

 The method appears to be specially adapted for seeking the typhoid 

 bacillus in stools.

Apparatus for Anaerobic Cultures.f— E.Turro claims that his simple 

 apparatus is an improvement on its predecessors for isolating anaerobic 

 bacteria. It consists (fig. 56) of a glass pan on the inside of which are 

 fixed three angular pieces of glass. These serve to support a round plate or
