Strontium Chloride.—With a solution of this salt of an equivalent strength 
to that of potassium and sodium chlorides, only a very small quantity of 
chlorine hydrate was formed at about 0°. Determinations were made with a 
solution diluted to double its volume for comparison with barium chloride.

An accident here interrupted the experiment. Hydrate formed abundantly 
at 0°, and began to decompose rapidly at about 9°. 
Calcium Chloride.—No chlorine hydrate was formed even at 7°:0, and when 
the solution at this temperature came in contact with some chlorine hydrate 
which had formed in the tube delivering the chlorine, decomposition took place 
with strong effervescence.

The curve constructed from these results is remarkable for its flat summit. 
It shows a maximum point, although there is no formation of chlorine hydrate. 
It might be supposed that this was due to non-saturation, but the same
