    undergoing great change of properties, was converted into a peculiar acid called the sulphovinic, consisting of Two equivalents of Sulphuric Acid. 40x2 = 80 Two equivalents of Alechol...... 23x2 = 46 Equivalent... 126 or, what is the same, of Two equivalents of Sulphuric Acid. 40x2 = 80 Six equivalents of Hydrogen ..... 1x6= .6 Four equivalents of Carbon ...... Ox4 = | 24 Two equivalents of Oxygen ...... Six.) 16 ——— Equivalent... 126 When an equivalent of this acid is heated it is decomposed ; the two equivalents of sulphuric acid, and one equivalent of water, remain in the retort, while the other elements combine to form an equivalent of ether, which is distilled ; thus : Sulphuric Acid. Gxygen. Hydrogen. Carbon. 1 eq. Sulphovinic Acid=80 + 16 +6 +4 24 Remain in the retort 80+ 8 +1] 126 89 i Il a ee Distilled... 8 +5 +24 = $7, ether. In the mode in which its constitution is here stated, ether is a mere ternary compound of its elements; it has however with great plausibility been supposed that two of these elements exist as a binary compound, and that it is united with the other to form ether. Thus it may be shown that the elements of ether are equivalent to, and have been supposed to exist as a dihydrate of olefiant gas; as a hydrate of etherine, that is of a peculiar carburetted hydrogen to which the name of etherine has been given ; lastly, it has been proposed by Dr. Kane (Dublin Journal of Medical Science, &c., January 1833,) to consider ether as a protoxide of etherewm, the name he gives to asupposed compound, consisting of the 4 eqs. carbon and. 5 eqs. of hydrogen which are contained in the ether. A similar view was soon afterwards promulgated by Berzelius, who gave the theoretic carburetted hydrogen the name of ethule. Preferring this to the other theoretical opinions, I shall exhibit the composition of ethereum, ether, alcohol and sulphovinie acid in accordance with it, referring to Turner’s Chemistry, and Brande’s Manual for further information, and for an explanation of the other opinions alluded to.
