also collected and a very complete resume of the whole subject was 

 presented. 



Mr. Mills thought that the experiments with rabbits, upon 

 which Dr. Koch placed so much stress, were scarcely conclusive, in- 

 asmuch as they are extremely liable to lung diseases. 



Dr. Hubbell agreed with Mr. Mills and said it was well 

 known that both rabbits and guinea pigs are very susceptible to all 

 scrofulous disorders. He believed that healthy people were fre- 

 quently inoculated by inhalations of infectious matter from tuber- 

 culous invalids. 



Mr. Pohlman had experimented with rabbits and had examined 

 their lungs and had never found them affected with tuberculosis. 



Dr. Ailing had verified every one of Dr. Koch's conclusions, 

 having followed his experiments, and had made repeated observa- 

 tions upon the bacilli of tuberculosis. 



Dr. Fell had examined the sputa of people afflicted with pul- 

 monary diseases, but had failed to recognize the bacillus, though in 

 the light of subsequent reflection he has little doubt of its presence. 



Dr. Barrett said it was yet a disputed question whether organ- 

 isms found in diseased tissues were the cause or effect of the malady. 

 It was persistently urged by good authorities that they were mere 

 scavengers accompanying and finding their proper pabulum and 

 habitat in the products of abnormal function. 



Prof. Kellicott said the same objections were urged against the 

 modern theory of fermentation, but they had been disproved and he 

 doubted not they would be in this case. 



The customary resume of current literature was presented by 

 Prof. Kellicott. 



Reports of personal work were made by a number of members, 

 but no abstract, as required by the society rules, was presented to 

 the secretary,

Meeting of November loth, 1882. 

 Dr. Wm. T. Belfield gave the history of several cases of para- 

 sitic diseases and showed and described their respective parasites, 

 among which were filaria sanguinis hominis, actinomyces bovis, and 

 bacilli of leprosy, splenic fever and tuberculosis and micrococci in 

 ulcerative endocarditis.
