Alcohol. — One table, made for the purpose of determining how 

 long the minimum quantity of alcohol used in some of the cultures 

 could provide sufficient food for an increase in growth, may not be 

 without interest and is here given as table I. The yield is given in 

 milligrams in all cases. 



TABLE I 

 Each flask received 0.46^ alcohol = concentration of o. 2 GM. per liter. 



All the cultures in each horizontal row are duplicates. An increase 

 in weight took place up to the tenth day, after which there was a 

 gradual loss, due to respiration. 



TABLE II 

 Each flask received 0.695m alcohol = concentration of 0.3 GM. per liter. 



TABLE III 

 Each flask received 0.468™ alcohol = concentration 0.2 GM. per liter.
