This chemically fixed ammonia is in proportion to 

 the amount of blood, as appears from a special experi- 

 ment tabulated below, which shows the greatest amounts 

 of 1/27 n ammonia and of 1/20 n sodium hydrate which 

 can be added to various amounts of blood without hae- 

 molysis occurring.

The calculated amounts af NaOH and NH 3 correspond 

 almost completely to the observed figures and the diffe-
