To these I add a series of observations of the osmose of the same salt in albumen, 
with the view of exhibiting the phenomenon in septa of that material. The well- 
preserved proportionality of the diffusate is remarkable.

Chloride of Barium . — Chloride of barium in its rate of diffusion from open vessels 
much resembles the chloride of sodium. Considerable analogy between the same 
salts is also observed in osmotic experiments.
