Pathogenic Bacteria. 67 



which naturally results from this circumstance is increased by 

 the fact thai it has been found impossible to produce the disease 

 in animals. It is possible to inoculate animals and to find that 

 they die, but such cases do not show the characters of the 

 disease as it occurs in the human subject. 



Such difficulties, however, do not gainsay the evidence which 

 we otherwise possess of the connection of the typhoid bacillus 

 with the disease. Since the place of the disease is in the intes- 

 tine, the rule which is observed in public health is to regard 

 any contamination of food or water used for drinking, with 

 intestinal excreta as a possible source of typhoid infection. 



The lecture was illustrated by actual specimens and by lantern 

 views. Mr. Mayne manipulated the lantern, and the slides, 

 which were referred to by the Lecturer as in every way suitable 

 for his purpose and generally approved of, were specially pre- 

 pared by Mr. J. J. Andrew. 



Professor Redfern moved, and Dr. Sheldon seconded, a 

 hearty vote of thanks to Professor Smith for his very instructive 

 lecture. 



The Chairman, in putting the motion to the meeting, said 

 they owed a great deal to such men as Dr. Smith, who put 

 forth such praiseworthy efforts in order to alleviate suffering. 



The motion was warmly passed. 



Subsequently an interesting exhibition of bacteria under the 

 microscope took place in the Library of the Museum.
