Liebig and Pelouze*, the name CEnanthylous acid. It is not 

 improbable that cenanthylic acid may be identical with the 

 azoleinic acid of Laurenlf; but he did not obtain it in a state 

 of purity. When the oenanthylate of silver is distilled, there 

 pass into the receiver an oil and a solid body, neither of which 

 possesses acid properties. The solid body is soluble in hot 

 alcohol, and on being allowed to cool, it crystallizes in beau- 

 tiful needles. 



Suberic acid is another product of the oxidation of castor 

 oil; it remains in the retort mixed with oxalic acid: it may 

 be purified by repeated crystallizations, and boiling with nitric 

 acid. 



Thus obtained and dried at 100° C, 0*2710 substance gave 

 •5490 carbonic acid, and 0'1990 water, or, in 100 parts. 

 Found. Atoms. Calculated. 



Carbon . . . 55-97 8 55-64) 



Hydrogen . 8-15 7 8-03 



Oxygen . . . 35-78 4 36*33

giving the formula C* H"^ O' + aq. 



The other acids found by Laurent did not appear to have 

 been formed ; but this is not affirmed with positive certainty, 

 as the examination was not proceeded with. A trace of lipinic 

 acid, however, may be obtained during the evaporation of the 

 fluid parts, pressed from the suberic acid. 



LXVIII. On Bleaching Salts. By M. Detmer, Esq.X 



A SHORT time ago a notice was published by M. Millon 

 -^^ on the Bleaching Salts of Chlorine, in which a new view 

 was offered of the constitution of these compounds. They have 

 for some time past generally been considered as compounds 

 or mixtures of a metallic chloride with a hypochlorite of a 

 metallic oxide; bleaching powder or the chloride of lime, for 

 instance, as consisting of chloride of calcium and hypochlorite 

 of lime, in single equivalents, the acid of the last salt contain- 

 ing one atom of oxygen to one atom of chlorine. The reac- 

 tion of chlorine upon lime supposed, may be very simply 

 stated : two atoms of lime lake up two of chlorine ; one atom 

 only of the lime is decomposed, of which the calcium and 

 oxygen respectively unite with an atom each of chlorine, form-
