where these latter cross each other, thus keeping its mean position on both 
sides of the maximum point. 
Cobalt and Sodium Chlorides.—Chlorine hydrate ae Ue at —4°, and was 
completely decomposed at +4. The curve in this case also runs between 
those of the single salts, crossing as in the preceding case.

Calcium and Sodium Chlorides.—No chlorine hydrate was formed at —5*, 
and the solution caused decomposition of the hydrates with effervescence, as in 
previous cases, The curve lies between those ‘of the single salts, but is below 
both after passing the maximum.

Cadmium and Sodium Chlorides.—Hydrate of chlorine formed easily. An 
accident happened at an early stage, but sufficient results were obtained to 
show that the curve lies between that of the single salts, at least before the 
maximum is reached.
