TEE MICSOOnOANISM CAUSING EPIDEMIC 

 POLIOMYELITIS^ 



From the facts presented it follows that by 

 employing a specially devised method there 

 has been cultivated from the central nervous 

 tissues of human beings and monkeys the sub- 

 jects of epidemic poliomyelitis a peculiar mi- 

 nute organism that has been caused to repro- 

 duce the symptoms and lesions of experi- 

 mental poliomyelitis. The microorganism 

 consists of globoid bodies measuring from 0.15 

 to 0.3 of a micron in diameter, and arranged 

 in pairs, chains and masses, according to the 

 conditions of growth and multiplication. The 

 chain formation takes place in a fluid me- 

 dium, the other groupings in both solid and 

 fluid media. Within the tissues of infected 

 human beings and animals the chains do not 

 appear. 



No statement is ventured at present as to 

 the place among living things to which the
