LIFE OF ELIE METCHNIKOFF 129 



And then he studied relapsing fever in order to 

 answer Baumgarten's objections, affirming that there 

 was no phagocytic reaction in that disease, though it 

 almost invariably ended in recovery. Experiments 

 on man not being possible, MetchnikofE procured

These researches on erysipelas and relapsing fever

 there no longer.

 burg, invited MetchnikofE to take charge of it. He

 opposition coming from all sides and devoid of 

 reasonable causes, I preferred to go abroad to look 

 for a peaceful shelter for my scientific researches."
