LIFE OF ELIE METCHNIKOFF 133 



On our way back we passed through Berlin, where 

 Metchnikoff wished to see Professor Koch and to 

 show him some interesting specimens of phagocytosis. 

 The great savant received him very coldly. For a

 During that time, Drs. Gamaleia and Bardach were 

 making anthrax vaccinations on a large scale in a 

 vast private property in the province of Kherson. 

 When we were settled in our country home, Metch- 

 nikofi received a telegram announcing that the first
