of this substance, Is that of becoming of a very intense blue, when in 

 contact with the persahs of iron. This color disappears when there 

 is an excess of acid, as is the case with morphine. It is not volatiHza- 

 ble, and not even completely fusible by heat, it being decomposed 

 when about to melt. The following are the analyses of these two 

 substances and morphine as made by M. Liebig :

29. A new Carburetted Hydrogen. (L'Institut, No. 114.) — 

 Dumas and Peligot, announce the discovery of a new compound of 

 carbon and hydrogen, which like the carburet C* H" and C^ H*, 

 will unite with two parts of water, and form a peculiar alcohol, and 

 with the various acids, and produce compounds analogous to the 

 common ethers. The composition of this new compound is repre- 

 sented by the formula C^* H^*. Thus there are four compounds 

 of carbon and hydrogen, which contain these elements in the same 

 ratio, but vary in their state of condensation, as the numbers 1 , 2, 

 4, 16. The existence of the compound C' ^ H' ^ has been proved, 

 ■ but its compounds remain yet unexamined. 



The compound C** H^^ is obtained by the distillation of ethal 

 in connection with vitreous or anhydrous phosphoric acid. It is a 

 colorless oily liquid, whose boiling point is about 260° C. 



From the preparation of this substance, as also from the analysis 

 of ethal, it is inferrible that this latter compound is composed of two 

 atoms of water, and one of the new carburet, and may therefore be 

 represented by the formula C*^* H^''+H'' O- ; consequently ethal 

 is a compound analogous to alcohol. To this base the name cetina 

 is applied, as it is obtained during the saponification of spermaceti. 



Dumas and Peligot have obtained a compound of cetina similar to 

 the hydrochloric ether, represented by the formula C"* H^*-j-Ch'^ 

 H^ ; also a substance, analogous in composition to the sulpho-vinate 

 of potash, represented by C^" H«* SO^'+KO, SO^' + H^^ O, and 

 termed sulpho-cetate of potash. This compound resembles much a 

 soap. The sulphoceiic acid may be formed by mingling sulphuric 

 acid and ethal. They have also found that spermaceti is a definite 

 compound, consisting of one atom each of oleic and margaric acids, 

 with three atoms of cetina, and three atoms of water. The hypoth-
