Brill: Infusorial Earth Extract 



203 



In order that a check might be kept on the activity of the 

 original extract of rice polishings, two chickens were treated 

 with 3 cubic centimeters of A on alternate days.

Three cubic centimeters of extract of rice polishings on alter- 

 nate days were insufficient to prevent the onset of polyneuritis 

 in chickens 1 and 4, but the extract prolonged the period of 

 good health. Two cubic centimeters of A given daily for several 

 days improved the condition of the chickens to such as extent 

 that they could be again placed on the original treatment. 



To determine if 50 grams of infusorial earth would extract all 

 the active substance from 500 cubic centimeters of hydrolyzed 

 extract of rice polishings, the experiments recorded in Tables 

 V and VII were planned.
