and green fluoreaoent solution was formed, though much tar 

 was left apparently unchanged. The aloohol was evaporated 

 off and the solution was filtered from tar. The fluorescent 

 filtrate was shaken with ether, by which the green substance 

 was roi^.oved, leaving the solution purple. The ether left, 

 on evaporation, a srrall quantity of a green substance having 

 a pleasant ester od©r. It was not examined* A portion of 

 the purple solution was exactly neutralized vath sodium car- 

 bonate. This solution gave a blue-black color with ferric 

 chloride which becarce red on addition of another drop of sodium 

 carbonate, indicating gallic acid. It also reduced Fehling 

 solution. 



Another portion of the purple solution was made alkaline 

 with sodium carbonate. A reddish-brown flocoulent precipi- 

 tate was formed and was filtered off. The filtrate did not 

 give any color with ferric chloride, but it reduced Fehling 

 solution* It also gave the test for rhannose with d-naph- 

 thol. 



The main portion of the purple solution was made alkaline 

 with sodium carbonate; the precipitate was filtered off and 

 dissolved in acetic acid. This solution was yellow and gave 

 a reaction with ferric chloride simmilar to that of gallic 

 acid. The filtrate from the precipitate by sodium carbonate 

 was concentrated by evaporation until sodium sulphate began 

 to crystallize out. Alcohol was added to precipitate the 

 sodium sulphate completely, the mixture was heated and filtered.
