xi THE ALBUMINOIDS 579 



It gives the biuret-, xanthoproteic-, lead-sulphide tests and the 

 Adamkiewicz reaction, but not that of Millon. When boiled with 

 HC1 it yields lysatinin, much amino-valerianic acid, also ammonia and 

 sulphuretted hydrogen, but little or no glutaminic acid, no tyrosin, and 

 no carbohydrate. Boiled with superheated water, or with caustic- 

 soda solution, it changes into albuminates, albumoses, and peptones. 

 Reticulin differs from all other albuminoids in containing phosphorus. 



Cuticulce of Worms. The cuticula of Lumbricus is, according to 

 Sukatschoff, 1 not chitin, but also an albumoid.
