"Dr. Koch's main theme was the best method for fighting tuberculosis 

 in the light of his experience gained in combating the bubonic plague, 

 cholera, hydrophobia, and especially leprosy, which he described as 

 caused by a parasite closely resembling the tubercle bacillus. 



"He pronounced hereditary consumption to be extremely rare, and 

 considered the sputum of a consumptive patient the chief source of in- 

 fection. He gave an account of recent experiments in Berlin, which 

 served to prove that human tuberculosis could not be transferred to ani- 

 mals. Lord Lister subsequently admitted that the evidence seemed satis- 

 factory, and Dr. Koch had also satisfied himself that the converse propo- 

 sition was also true and that human beings were not susceptible to bovine 

 tuberculosis communicated through milk, butter, and meat. This con-

 Koch, and several experts from the continent talked over the matter with 

 various results.

 tubercular cattle was hardly greater than by hereditary transmission, 

 and that measures against it were inadvisable.

 measures, and explained how much good work had been done by the 

 consumptive hospitals in England. He also highly praised Dr. Briggs' 

 system and organization in New York as worthy of study and imitation 

 by all municipal and sanitary authorities.

"The feature of today's session of the British congress on tubercu- 

 losis was Dr. Robert Koch's paper, which was listened to with the deep- 

 est interest by a big gathering in St. James' hall. Lord Lister (professor 

 of surgery in the Glasgow and Edinbrugh universities and one of the 

 British vice presidents of congress) introduced the noted German pro- 

 fessor to the assembly with highly complimentary words. 



"During his address Dr. Koch said his experiments had satisfied him 

 that human tuberculosis and bovine tuberculosis were radically different
