in general, and the specialisation of some forms into pro- 

 ducers of disease. The consideration of the occurrence of 

 these bacteria in the surroundings of the sick, and even 

 upon the healthy skin, led up to an account of Lister's 

 institution of methods for preventing their entry into 

 wounds, and its development into the modern system of 

 aseptic surgery and of the principles underlying the hospital 

 isolation of the infectious sick, and disinfection. The 

 means by which infectious bacteria gain access to the sur- 

 face of the body, and the events connected with their 

 entrance to, and development in the internal tissues were 

 dealt with at length. It was pointed out that the mani- 

 festations of these diseases depend upon the injury done to 

 the tissues by the poisons or toxins produced by the bacteria, 

 and that recovery from tliem is consequent on the elabor- 

 ation of neutralising substances or antitoxins by the cells 

 of the body. Reference was then made to the after effects 

 of these diseases, including the immunity against subse- 

 quent attacks, and in this connection attention was called 

 to the use of viruses, vaccines, and prophylactics as pre- 

 ventives and of antitoxic serums as cures for infectious 

 diseases.
