Pneumo-Enritetis a contagious disease in pigs, and last of 

 all as you know, Koch is at present engaged at Calcutta in 

 investigating the nature of Cholera, and his most recent 

 reports appear to show that he has discovered a Bacillus 

 which is altogether peculiar to cases of this disease. His 

 principal difficulty at present is that he has hitherto been 

 unable to produce Cholera in any of the lower animals, and 

 thus to test the power of this particular organism. 



Had I not already detained you too long, I should have 

 said something about the Bacillus Tuberculosis, the organism 

 found in cases of consumption. I have, however, placed a 

 specimen under one of the microscopes on the table. 



With such evidence as this before us, it seems to me 

 that the advocates of the Bacterial origin of certain diseases 

 have made out a very strong case in their favour. 



In retiring from the office of President it only remains 

 for me to thank you all most sincerely for the kind co- 

 operation and hearty support you have accorded me during 

 my term of office. I must also thank the members of the 

 Council and especially our Honorary Secretaries for the 

 ready and invaluable assistance they have given me on all 

 occasions. In electing my successor you have chosen a 

 gentleman of such high scientific attainments that I look 

 forward confidently to the continued prosperity of our 

 Society, the success of which we all have so much at heart.
