growth. The varioiis functions as thus outlined are probably over- 

 estimated, but those who have worked in this field seem to be 

 strongly of the opinion that inosite-phosphoric acid is more than 

 a reserve material. It is attracting considerable attention and as the 

 necessary analytical methods are perfected, we may expect to 

 see, in increasing number, valuable contributions that will eluci- 

 date in detail the part which this interesting Compound plays in 

 nature.
