hypothetic or come about with great difficulty. He succeeded in 

 keeping human and also bovine types of tubercle bacilli alive in 

 tortoises for twelve months, at the end of which period each was 

 found unmodified and possessed of its original characteristics. 



It was Koch's hope to be able to finally settle the whole matter, 

 and to this end he asked the cooperation of many laboratories 

 throughout different parts of the world. Unfortunately he died 

 before the results could be compiled, but much work had been done 

 and much support thereby given his views. A most fertile research, 

 the results of which form a valuable addition to our knowledge of 

 the problem has been published by Park and Krumwiede,* who, 

 basing their opinions upon the following tabulation of 1224 cases, 

 come to the following conclusions :

Conclusions. — Bovine tuberculosis is practically a negligible 

 factor in adults. It very rarely causes pulmonary tuberculosis 

 or phthisis which causes the vast majority of deaths from tuber- 

 culosisln man, and is the type of disease responsible for the spread 

 of the virus from man to man.
