whether it was homogeneous or not but the analytical results agree 

 approximately with inosite triphosphate minus one molecule of 

 water. The substance may therefore be a partial pyrophosphoric 

 acid ester of inosite or it may represent some complex decomposition 

 product of phytic acid. 



In conclusion we present a summary of the analytical results 

 of the preceding crystalline barium salts in comparison with the 

 calculated percentages required for the usual phytic acid formula 

 and inosite hexaphosphate.

Addition of Alcohol. 



Table II. — Barium Salts Crystallized from Dilute Hydrochloric Acid in 



the Presence of Barium Chloride.
