Dr. Kane found the ammoniacal chloride of copper to 
be cucl +2 Nu, + Ho. or correctly, NH3.H cl + NH;. CuO. 
By heat nu; uo is lost, and there remains NH3.Hcucl. By 
water there is generated a new basic chloride of copper, 
having the formula cw cl + 4cuo+6uno. The common 
Brunswick green cu cl + 3 cu o+4no. Dr. Kane has ob- 
tained with6 no in place of 4 no. and these oxychlorides he 
considers as formed on the type of the ordinary chlorides, 
combined with water, or with metallic oxides in other groups. 
1—cu. cl +cuo +2 (cwo + 2 Ho) 
2—cu cl + 3 (cu 0 + 2 HO) 
3—cu cl +cuo + 3(cuo +2 HO). 
When No. 2 is heated, it loses all water, but if then put 
into contact with water, it regains 4110, and becomes perfect 
Brunswick green No. 1. cucl.cuo +2 (cuo + 2H). 
The second equivalent of oxide is, in these chlorine 
bodies, much less forcibly held than in the sulphates, but 
that it is differently related to the acid than the remaining 
equivalents of oxide or of water is proved by a great variety 
of facts. 
The ammoniacal nitrate of copper has the formula cuo 
No; + 2 NH3. or (NH3.-HO.) NOs + CU NH2. hence this body 
contains, united with the copper, amidogen ; when heated it 
explodes, the copper and amidogen burning in the nitrous 
oxyde yielded by the nitrate of ammonia. To obtain some 
analogical evidence regarding this body, Dr. Kane re-ex- 
amined the ammonia-sulphate and nitrate of silver, and found 
George Mitscherlich’s results good. Dr. Kane, however, 
writes the formule . 
1 — (NH3.HO>, RO; + Ag.NH2 
2 — (NH3.HO) NO; + Ag NHp. 
This last salt, when heated, gives a beautiful decomposition ; 
the nitrate of ammonia fuses readily, and at a temperature 
below that at which it decomposes, the amide of silver is 
resolved into ammonia, nitrogen, and metallic silver, which
