60 Analyses of Bookf» [J AH, 



Ferrane has a greyish but variegated colour, metallic splen- 

 dour, and a lamellated structure. It dissolves in water, and 

 4brms the green muriate of iron. 



Ferranea is a volatile substance, vi^hich condenses in the form 

 of small irridescent plates. It dissolves in vv^ater, and forms red 

 muriate of iron. 



4. A compound of manganese and chlorine may be obtained 

 by evaporating to dryness the white muriate of that metal, and 

 heating the residue to redness in a glass tube with a very small 

 orifice. It is a beautiful substance, of a pink colour, great 

 brilliancy, and a lamellar texture. By forming this compound, 

 and dissolving it repeatedly in water, the manganese may be 

 freed from iron, as the compound of the latter metal with iron 

 is volatile, 



5. The compound of chlorine and lead may be obtained by 

 fusing muriate of lead in a glass tube with a narrow orifice. Its 

 properties are sulBciently known. 



. 6. The compound of chlorine and zinc was obtained by eva- 

 porating to dryness the muriate of zinc, and heating the residue 

 to redness in a glass tube. Like piumbane, it does not sublime 

 at a red heat. It melts before it is red hot ; and on cooling 

 becomes viscid before it acquires hardness. It is very deli- 

 quescent. 



7. The compound of chlorine and arsenic, or arsenicane, has 

 been long known, under the name of the fuming liquor of 

 arsenic. It may be made by burning arsenic in chlorine gas, ot 

 by distilling a mixture of six parts of corrosive sublimate, and 

 one part of arsenic. Its properties are pretty well known. It 

 dissolves sulphur and phosphorus while hot, but lets them fall 

 again as it cools. It dissolves resin, and combines with oil of 

 turpentine and olive oil. 



8. Butter of antimony, by which name the combination of 

 antimony and chlorine was formerly known, may be obtained by 

 distilling a mixture of 2i parts of corrosive sublimate, and one 

 part of antimony. Its properties are well known. 



9. Bismuthane may be obtained by distilling a mixture of 

 two parts of corrosive sublimate, and one part of bismuth. It 

 is of a greyish white colour, opake, uncrystaliized, and of a 

 granular texture. In a glass tube it bears a red heat without 

 subliming. 



The following table exhibits the result of Mr. Davy's experi- 

 ments on the combinations of dilFerent metals with chlorine, 

 oxygen, and sulphur. I have added a column indicating th$ 

 proportions of these bodies from theory, that it may be seen how 

 nearly Mr. Davy's experiments approach to it.
