lysis is rather too small ; but similar errors are inevitable with bodies 

 which are uncrystallizable and difficult to burn. M. Arppe ob- 

 tained still less carbon (61*2) than the authors. 



Boiling nitric acid attacks sulphomoqmide and forms sulphuric 

 acid ; water added to the solution precipitates a yellow flocculent 

 matter, soluble in ammonia. As no gas is liberated during the for- 

 mation of sulphomorphide, and as the sulphuric liquid contains no 

 other substance, the formula given seems sufficiently controlled by 

 the preceding analysis. 



Sulphonarcotide. — When narcotina moistened with water is heated 

 with a slight excess of sulphuric acid, a solution is obtained which 

 becomes of a deep brown colour when more strongly heated, and 

 eventually thickens. No gas is liberated during this reaction ; the 

 mixture is to be diluted with water and boiled, thrown on a filter 

 and washed with cold water, in which it appears to be insoluble. It 

 dissolves in alcohol, but it is not deposited from it in crystals. 



This product behaves like sulphomorphide ; when calcined on 

 platina foil, it yields much charcoal very difficult to burn ; subjected 

 to distillation, it yields water and oily matter of a foetid odour. By 

 analysis 100 parts yielded

These correspond to a formula represented by neutral sulphate of 

 narcotina, minus two equivs. of water, SO 4 (H 2 , 2C 23 H 25 N07)— 20H 2 . 

 This formula requires —

H 4 s 48 5-2 



N 2 28

Ammonia does not act upon sulphonarcotide, potash dissolves it 

 with a brown colour, and acids separate in the green state. When 

 boiled with nitric acid, sulphonarcotide gives sulphuric acid, and also 

 a yellow matter soluble in ammonia. 



Sulphomorphide and sulphonarcotide evidently belong to the same 

 class of bodies as the amides and the anilides ; they are to the sul- 

 phates of morphia and narcotina, what sulphamide and sulphanilide 

 are to the sulphates of ammonia and aniline. Certainly it has not 

 been possible to separate morphia and narcotina from them ; but it 

 must be remembered, that with respect to the anilides this regenera- 

 tion requires the intervention of a high temperature, and that this ne- 

 cessarily acts destructively on non-volatile alkaloids, like morphia 

 and narcotina. — Ann. de Ch. et de Phys., Septembre 1848. 



COMPOSITION OF URANITE AND CHALKOLITE. 

 BY M. WEItTHER. 



The specimen analysed by M. Werther was from Gunnislake 

 Mine, Cornwall. He operated on a well-crystallized specimen. His 

 results were as follows : —
