CHINOLINE AND ITS HOMOLOGUES. 385 
I obtained, however, an accurate result by precipitating with sulphuretted hydro- 
gen, and collecting the sulphide of cadmium on a weighed filter.

It is evident, therefore, that the formula for the salt dried at 212° is— 
y C,, H, N, HCl+2 CdCl. 
Several examples of salts of the same constitution occur in inorganic chemistry, 
some of which have been examined by M. Von Haver, who terms them chloro- 
_ bicadmiates. The chinoline salt, if merely dried by exposure to the air, contains 
two equivalents of water, for at 212° it loses 5:41 per cent.; theory requires 4-91. 
_ The excess arises from a little moisture adhering somewhat tenaciously to the 
crystals. 
_ Hydrochlorate of Chinoline and Chloride of Uranyl._—tIf double carbonate of 
uranium and ammonia, dissolved in hydrochloric acid, is added to a strong 
solution of hydrochlorate of chinoline, the fluid rapidly becomes filled with short, 
| drilliant, yellow needles, and in a few minutes the whole fluid solidifies, so that 
the vessel may be inverted without the contents escaping. From more dilute 
solutions, prismatic crystals are deposited, sometimes of considerable size. The 
salt is of a rich yellow colour, and is very soluble in water. It was quite free 
from any trace of ammonia. The mother liquid was removed by washing with 
probol. The quantity at ony eal was too small to allow of a complete exa- 
6°760 grains of uranium salt of asain dried at 212°, gave
