The formula— 
C,, H, N, HCl, + (Ur, 0,) Cl, 
appears, therefore, to be the correct expression of the analysis, and it ‘agrees in 
constitution with the anhydrous ammoniochloride of uranyl of Prticor. It is 
my intention to examine the double compounds of uranium with other organic 
bases. 
Binoxalate of Chinoline.—The great discrepancy in the results of Runer and 
HorMann with regard to the oxalate of chinoline, made me desirous of ascertain- 
ing the nature of this salt. According to the former chemist, leukol (chinoline) 
has such a great tendency to form a crystalline oxalate, that this property is its 
marked characteristic; Hormany, on the other hand, could only obtain it in the 
form of a confused, radiated, glutinous mass, deposited when the solution had 
reached a certain state of concentration. I found, however, that if 24:3 parts of 
chinoline are added to 16:5 parts dry oxalic acid, dissolved in a small quantity of 
water, the whole solidifies to a white crystalline mass, of the consistence of soft 
cheese. The salt cannot be obtained pure by a random admixture of the ingre- 
dients, as, although the chief tendency appears to be to form the binoxalate, yet 
other compounds are also formed in sufficient quantity to prevent constant ana- 
lytical results from being obtained, unless the above proportions are used. The 
salt, before being employed for analysis, must be recrystallized from alcohol once 
or twice, when it forms fine silky needles. It is partially decomposed by expo- 
sure for two days to 212°, with evolution of chinoline, a salt being formed inter- 
mediate in composition between the binoxalate and quadroxalate. It is necessary, 
therefore, to dry it for analysis im vacuo over sulphuric acid. 
6:995 grains of binoxalate of chinoline, dried in vacuo, gave 
15,407  ~... ~~ carbonic acid, and 
2,798 .... water.
