    These radicals also enter into the composition of the normal series of fatty acids. The following list contains all the radicals of this section that have been hitherto obtained :— CtL ' Methyl Ethyl ., Propyl. Butyl Amyl ., f Me I hie’ CIL Boiling- points. not known.

By the action of zinc on the iodides of the normal radicals:— 2C(0.H„.)H.I + Za = Znl. + { Part of the liberated radical is at the same time decomposed into the hydride of the radical and the corresponding dyad radical:— /C(C„H,„+0H3 _ fC(C„ir,„+0H3 , rcfCTf M-ll [ C(c„h,„+i)H, ~ 1 h + LC(t„H„.+on] . A remarkable special method for preparing ethyl consists in exposing mercury and cthylic iodide to tlie influence of sun¬ light : Ilg = 2EtI + Ethylic HgT^ + Et^. Morcuric Ethyl,
