tuents of 1 equiv. ammonia and of 1 equiv. aniline. The action of 

 sulphuric acid is equally distinct, and supports my opinion ; it fur- 

 nishes, in fact, sulphanilic acid and sulphate of ammonia, with disen- 

 gagement of carbonic gas : —

By acting with cyanic acid upon aniline, M. Hofmann obtained 

 a substance to which he likewise assigns the composition of anilamic 

 urea. As this chemist has merely announced the production of this 

 substance vvithout describing its properties, I am not able to assert 

 their identity. 



Carbanilamide possesses the following properties : — It is soluble 

 in water, alcohol and aether: its alcoholic or aethereal solution 

 quickly acquires a dark red colour, and appears to experience some 

 change, but its aqueous solution is not altered, and furnishes on 

 spontaneous evaporation very beautiful, transparent, flattened prisms 

 of considerable size. The crystals have no odour ; they have a cool, 

 very slightly bitter taste, similar to nitre ; they contain 1 equiv. 

 water of crystallization, melt at 161°, and are decomposed at a 

 higher temperature, leaving a large amount of carbon. 



Carbanilamide, like urea, combines with acids and metallic salts, 

 furnishing crystalline compounds. I have analysed the following : — 



The nitrate C^ H^ N^ O, NO^ H 



The argentonitrate C H^ N^ O, NO^ Ag 



The chloride. C^ Hs N^ O, CIH 



I likewise obtained the hydrargyrochloride and the platinochloride. 

 In concluding this extract, I may state that I have also analysed 

 the aethers of nitrobenzoic acid ; that from alcohol crystallizes 

 in right rhombic prisms of 122"; my analyses confirm those of 

 M. Kopp ; that from pyroligneous aether crystallizes in nearly the 

 same form (118° to 120°) ; the two aethers are consequently isomor- 

 phous. — Comptes Rendus, Feb. 26, 1849. 



ON THE COMPOSITION OF STEARIC ACID. 

 BY MM. LAURENT AND GERHARDT. 



According to the most recent analyses which have been made in 

 Germany by the process generally in use, and under the direction 

 of M. Liebig, the composition of stearic and margaric acids came 

 to the support of the theory of organic radicals, by assigning to 

 the-<e acids formulae similar to those of hyposulphuric and sulphuric 

 acids. In a word, these two acids, supposed in the anhydrous state, 

 presented two different stages of oxidation of the same radical,
