Table A' shows that quahtatively the two organisms behave 
aHke in their abihty to use all the carbon compounds tested. 
Quantitatively there is considerable difference, both as to rate of 
consumption and total growth after 12 days. F. oxysponim in 
general shows the greater speed of growth and greater growth after 
twelve days. In some cases F. trichothecioides shows the greater 
growth after 12 days.

Table \'III gives the dry weight formed by the organisms when 
carbon acids were furnished as carbon sources. X 100 solutions 
were used, excepting for asparagin and asparagenic acid, whose solu-
