COMBINATIONS OF OXIMURIATIC ACID AND METALS. 17 



Staonane is fusible at a heat below that of dull redness; it 1st conaponrsd 

 bears ttiis tea>peratiire, if uir be nearly excluded, without 

 undt-rgoing any change; but when subjected to a heat as 

 stroiiif as glass will bear without being fused, it appears 

 to be, from the slight fume produced, partially decomposed. 

 It aifords the hquo.r of Libavius when heated with cor- 

 rosive sublimate, nilrt, red oxide of mercury, or with the 

 hy pel oxi muriate of potash. In the last three instances, oxide 

 t)f tin is also formed; and with the hyperoximuriaxe, the 

 action is so violent, that intlammatiou is actually produced. 



The liquor of Libavius and aurum musivum are formed 

 wlien stannaue is heated with sulphur. 



fellaimaue, by the action of water, appears to be converted r 



into the insoluble subaiuriate of tin, and the acidulous 

 muriate. 



The vstannanea, or liquor of Libavius that I have examined, 2(\ compound 

 was made by heating togetlier an amalgam of tin and cor- o^^'quor of 

 rosive sublimate, m the proportions commonly recommended. 

 I have obtained this compound in another way, by treating 

 the cpacentrated solution of the peroxide of tin in muriatic 

 acid, with strong sulphuric acid ; a gentle heat applied to 

 this mixture contained in a retort, expels the fuming liquor, 

 which may be condensed, as usual, in a cold receiver. 



The only new and remarkable property, which I have ob- itsactionon 

 served the liquor of Libavius tc possess, is its action on oil of °'' of lurpen- 

 turpentine. I was led to make trial of it from an idea of 

 sir Humphry Davy, thai ihe combinations of the metals and 

 chlorine might be soluble in oils.. In the first experiment, 

 when I poured the fuming liquor into the oil, inflammation 

 immediately took place, with violent ebullition and pro- 

 duction of dense reddish fumes. I have used other speci- 

 mens of oil of turpentine, expecting a similar inflammation, 

 but without its occurrenre, though there has been in every 

 instance a considerable action. The mixture of the two 

 being made in a retort connected with mercury, no gas was 

 generated, oxide of tin appeared to be formed, and a viscid 

 oil was produced, which, like the fat oils, left a permanent 

 stain on paper, and had little smell or taste, and which, di- 

 gested with alcohol, imparted something which occasioned a 

 permanent clondiness on the admixture of water, and an
