SYSTEMATIC AND DESCRIPTIVE. 2OI 



A beneficial result was obtained in cases of lupus, 

 cancer, and sarcoma, this being the object for 

 which the latter inoculations were undertaken.* 



The appearances of cultivations very strongly 

 resemble those already described in Streptococcus 

 pyogenes. There is less tendency, however, to the 

 formation of terraces, the edge of the growth is 

 thicker and more irregular, and the appearance of 

 the streak is more opaque and whiter.t 



Streptococcus toxicatus, Burrill. Globular 

 cells, '5 //, in diam., singly, in pairs, and rarely in 

 chains. They occur in species of R'hus (Sumacli), 

 and have been credited with being the cause of the 

 inflammation which is produced by the poison of 

 the plant. 



Streptococcus in puerperal fever. Cocci in 

 zooglcea, and sometimes in chains, have been ob- 

 served in all organs affected in puerperal fever, and 

 especially in the endocardium, lung, spleen, kidney, 

 and brain. 



Streptococcus in endocarditis, Klebs Cocci 

 i [L and '5 p. in diam., and chains. They have been 

 observed in masses upon the altered valves and in 

 the detritus of the ulcerations of the endocardium

\ In this and many similar cases the cocci are given as distinct 

 species from their association with particular diseases, not because 

 they are believed to be causally related, for there is very little 

 evidence in favour of that belief as yet, but purely for convenience 

 of reference. In many cases they are probably only septic organisms, 

 which have found a pabulum in the dead tissue ; others appear to be 

 identical with organisms which have been found in pus.
