is soluble with effervescence in nitric acid, and without effervescence 

 in muriatic. It consists of 36 chlorine, and 64 copper. 



In the other compound, which the author calls Cupranea (a term 

 that, in the language proposed by his brother, implies a substance 

 containing more acid), the proportions are 53 chlorine, and 47 copper. 

 This compound is also best obtained from the common deliquescent 

 muriate by slow evaporation, carried ultimately to dryness, at a tem- 

 perature not exceeding 400 of Fahrenheit ; for if greater heat be 

 applied, one portion of chlorine is expelled, and what remains is re- 

 duced to the state of cuprane and resin copper. 



In addition to the foregoing, there is also a native muriate of 

 copper, which, by the author's analysis, consists of 73 brown oxide, 

 16' 2 muriatic acid, and 10' 8 water. 



This compound has also been imitated by Proust ; and Mr. J. Davy 

 has also found various methods of making the same combination. 



Tin also forms two compounds with chlorine, one already known 

 under the name of the fuming liquor of Libavius, which the author 

 calls Stannanea, most readily obtained by heating together an amal- 

 gam of tin with corrosive sublimate ; and a second analogous to the 

 former, made by the substitution of calomel, and accordingly con- 

 taining a less proportion of chlorine, and therefore called stannane. 

 The former contains 42*1 tin, with 57'9 chlorine. 

 The latter 62'22 tin, 37' 78 chlorine. 



The only new and remarkable property of the liquor of Libavius 

 observed by Mr. J. Davy, is its action upon oil of turpentine, which 

 in one experiment was so violent as to occasion inflammation. In 

 other instances oxide of tin seemed to be formed, and a tenacious oil, 

 having a smell somewhat like camphor. 



Beside these compounds of tin with chlorine alone, there is also a 

 submuriate observed by Proust, containing about 70'4 grey oxide, 

 19 muriatic acid, and 10' 6 water. 



With iron likewise, as well as with the former metals, there are 

 two compounds with chlorine, which may either be formed by direct 

 union with oxymuriatic gas, or may be obtained by evaporating to 

 dryness the green and red muriates of iron. When thus deprived of 

 water, they receive the name of Ferrane and Ferranea. The former 

 contains 46'57 iron, and 53'43 chlorine; the latter 35' 1 iron, and 

 64-9 chlorine. 



With other metals that have been tried by the author, such as man- 

 ganese, lead, zinc, arsenic, antimony, and bismuth, he has not found 

 that chlorine combines in more than one proportion. 



The compound with manganese bears a red heat, in close vessels, 

 without decomposition ; but when it is heated in an open vessel, mu- 

 riatic acid fumes are evolved, and oxide of manganese remains. It 

 appears to consist of 54 chlorine, and 46 manganese. 



The muriate of lead, known by the name of Horn lead, but called 

 by the author Plumbane, was found to contain 74'23 lead, and 25-77 

 chlorine.
