advantageously employed, to determine by a simple proof the pre- 

 sence of one of these substances in a coagulated state. 



If the elementary composition of these three bodies be regarded 

 independently of the ashes, it will be observed that their composition 

 is almost exactly the same ; this is shovv^n by the follow^ing table : 



Albumen. Fibrin. Caseum.

 M. Vogel expresses his belief that the numerous analyses which 

 have been cited, lead to the important conclusion already drawn by 

 M. Mulder respecting albumen and fibrin, namely, that albumen, 

 fibrin, and caseum have in the animal kingdom, the same intimate 

 relation that sugar, starch, and gum have in the vegetable kingdom ; 

 this observation if followed out, promises to give the most interest- 

 ing and important explanations respecting a great number of the 

 phaenomena of animal organization. — Journal de Fharmacie, Sep-

ON SULPHATE OF CHLOUIDE OF SULPHUR. BY H. ROSE. 



Some attempts which were made to convert the sulj)hate of chlo- 

 ride of sulphur, S Cl^-f 5S, by taking sulphuric acid from it, into a 

 compound analogous to the chromate of chloride of chromium, 



Cr Q3 + 2Cr, did not yield satisfactory results. 



If chloride of sodium be treated with sulphate of chloride of sul- 

 phur, they unite to form a solid transparent mass, which does not 

 emit fumes, but which when heated yields a vapour having a 

 strong smell of chlorine, and which nevertheless is undecomposed 

 sulphate of chloride of sulphur, containing free chlorine. If it be 

 submitted to distillation, the latter escapes as soon as ebullition 

 occurs. By the decomposition of the chloride of sodium sulphurous 

 acid is eventually disengaged, and there remains a mixture of super- 

 sulphate of soda and undecomposed chloride of sodium. 



The sulphate of chloride of sodium [sulphur?] decomposes at a 

 temperature much above its boiling point. If the vapour be con- 

 veyed through a glass tube heated to redness, chlorine gas as well 

 as sulphurous acid are evolved, but the presence of the latter is not 

 discoverable on account of that of the former. The liquid obtained, 

 after numerous researches into its nature, appeared to be a solution 

 of anhydrous sulphuric acid in sulphate of chloride of sulphur, 

 in which the first partly crystallizes by cooling. It is not possible to 

 procure by this process, a definite compound of chloride of sulphur 

 and sulphuric acid. 



The specific gravity of the vapour of sulphate of chloride of sul- 

 phur, was found by a mean of five trials to be 4*481. Supposing it to 

 be a compound of 6 volumes of chlorine representing 3 double 

 atoms, and 2 volumes of vapour of sulphur, corresponding to 6
