These preparations were found to have the following compositions 



Preparations 62 and 6j.

Preparations 64 and 65. 



The residues which remained after treatment with alcohol of 0.820 sp. gr. 

 were then dehydrated with absolute alcohol and digested with ether. From 

 extract i preparation 66 was obtained, weighing 63 grams ; from extract 

 2 preparation 67, weighing 2.1 grams, and from extract 3 preparation 68, 

 weighing 41.2 grams. 



Preparation 66, which constituted the principal fraction of the protein 

 extracted, was further treated in the following manner : 20 grams were 

 dissolved in 250 cc. of 0.90 sp. gr. alcohol and found to yield a clear solu- 

 tion, which was then poured into 800 cc. of absolute alcohol, whereby a 

 considerable precipitate was at once separated, leaving the solution milky. 

 This substance was dehydrated with absolute alcohol and digested with 

 ether, yielding preparation 69. The filtrate was then treated with a few 

 drops of 10 per cent sodium-chloride solution, causing a heavy precipitate, 

 which on stirring rapidly agglutinated and adhered as a mass to the stirring-
