The Action of Sodium Chloride on the Coagulation Point 
of Vitellin. 
Some vitellin was dissolved in 5 per cent, solution of common 
salt. It was saturated with the salt, and a precipitate of globulin 
filtered off. 
(a) Vitellin, dissolved in saturated solution of common salt, 
became opalescent at 70° C., and coagulated at 76° C. 
(b) Vitellin, dissolved in 20 per cent, solution of common salt, 
became opalescent at 83° C., and coagulated at 89° C.
