" Determined as phytin phosphorus. These inositol weights were calculated from Courtois and Perez 

 values for phytin phosphorus, assuming a formula Ca5Mg(C6Hi2024P6-3H20)2 for phytin. 

 This included 1340 7 of free inositol and 1860 7 of bound (phytin) inositol. 



hexane which is an analog of either the scylHtol structure (1)" or the myo- 

 inositol structure (11).'- It has been observed'^ that lipositol from brain

inhibited the action of streptomycin on Staphlococcus aureus, and a con- 

 firmation of this observation has been reported.'^ However, it has been 

 found'^ that hpositol has no antistreptomycin effect on Escherichia coli. 

 Another relationship between inositol and streptomycin has been re- 

 ported.'^ The yeast Torula utilis was adapted to grow on a medium con- 

 taining inositol in place of glucose. In contrast to the parent strain, this 

 yeast which had been adapted to inositol was sensitive to streptomycin.
