rAGK 



The streptococcus described by Klein in 1882 is probably the 

 specific cause of scarlet fever — Distribution of the disease-r 

 Mortality greatest in young children — Difficulty of exercising 

 sanitary control owing to the nature of the infective material — 

 Pathogenesis — Epidemics — Successful treatment of cases with 

 Marmorek's antistreptococcic serum. 



SMALL-FOX AND VACCINIA. 



Evidence of the probability of a bacterial agency in vaccine lymph 

 — Besearches of Dr. Copeman — Glyoerised lymph— Successful 

 - culture of the small-pox bacillus in an egg — Experiments by 

 Dr. Copeman as to the production of vaccine with the culture 

 so obtained — Distribution and pathogenesis of small-pox — The 

 infection is air-borne for very considerable distances — Pre- 

 ventive measures. - 



HYDHOPHOBIA. 



The specific organism is not yet discovered — Incubation period — 

 Examination of suspected animals — Post-mortem appearances 

 — Pasteur's method for the production of immunity — Treat-

 has been received — Eeport of the English Commission on
