Chloride of Calcium . — The diffusion of chloride of calcium in open vessels has 
been observed to fall below that of chloride of barium as 7*5 to 6'5*. But in 
membrane, judging from the following observations, the diffusion of chloride of 
calcium is the more rapid of the two. The osmose has also a tendency to rise, 
particularly in the larger proportions of chloride of calcium. The replacing water 
often exceeds twice the weight of the salt diffused.
