41 8 "Tannin Masses" in Fruit of the Persimmon [April 



A study of the conditions necessary for the formation, and also 

 the hydrolysis, of the phloroglucinol-tannin combination might help 

 to explain the nature of the ripening- process in persimmons. 



This work resulted from a Suggestion by Prof. F. E. Lloyd to 

 Prof. Wm, J. Gies, that material would be supplied in abundance 

 for a study of the "tannin mass." I am indebted to Professor 

 Lloyd not only for the material but also for many suggestions. To 

 Professor Gies I am likewise indebted for helpful advice.
