94 SUMMARY OF CUliEENT RESEARCHES RELATING TO 



Diplococcus of Rheumatism and Appendicitis.* — F. J. Poynton 

 and A. Paine record some important and interesting experiments made 

 with the micrococcus of rlieumatism. By injecting this organism into 

 the blood-stream of rabbits, they were able to produce acute appendicitis, 

 accompanied by arthritis. The diplococcus used was isolated from the 

 knee-joint of a boy suffering from rheumatic fever. 



Bacillus thermophilus vragnensis.f — P. Georgevitch describes 

 the process of formation and germination of the spores in B. thermo- 

 philus vragnenus. The cultivations were carried on at a temperature 

 of from 56-60° C. The first indications are the presence of chromatic 

 granules, which stain deep red with dahlia. These granules tend to 

 agglomerate towards one pole, and are soon surrounded by a membrane. 

 When the spore attains its definite dimensions the bacillary sheath bursts 

 and sets it free. In its early stage the spore is stained with difficulty, 

 but as the embryo begins to appear the latter is easy to determine, as 

 it is very chromophilous. The embryo increases in size, and eventually 

 escapes by bursting the spore-case.
