1916] LINK—FUSARIUM 203 
bility permitted only N/200 solutions. In the case of the higher 
fatty acids and oils, the material was weighed out as though N/ 100 
solutions were being prepared. With these no weighings of the 
material formed were attempted, but merely differences in luxuri- 
ance of growth were recorded. To those acids which showed no 
growth with N/too solutions, 5 cc. of ro per cent glucose solution 
was added, making the sugar concentration 1 per cent, so as to 
determine whether the acid was merely non-usable, or whether 
it was toxic. Since it was found that some were toxic at N/100 con- 
centration, lower concentrations were made up also. The results 
are given in table
