    XIII, —Extract from the “Preliminary Report on the Recent Progress and Present State of Organic Chemistry,” by George C. Foster, B.A., F.C.S., read before the Meeting of the “ British Association for the Advancement of Science” held at Aberdeen, in September, 1859. “ In conclusion of our account of the recent advances of Organic Chemistry, we may enumerate some of the most important reactions, or methods of transformation, which, within the last four or five years have been shown to be applicable to the compounds of various groups, or which, from their nature appear to be capable of such a general application. They may be divided for this purpose into —(I.) Heterologous transformations, . . . (II.) Homolo¬ gous transformations, . . . (III.) Isologous transfor¬ mations. (I.) Heterologous transformations, . . . (E) The sub¬ stitution of potassium and sodium for zinc in combination with methyl or ethyl (Wanklyn) . . . (II) Homologous transformations. (A) The combination of carbonic anhy¬ dride with the compounds of the alcohol-radicals with alkali-metals, e. g. C H Na -h CO = C H Na 0 (Wanklyn) 3 2 2 3 2 j Sodium-methyl Acetate of Sodium. XIV. —Extract from the “ Lehrbuch der Organischen Chemie von Dr Aug. Kekule,” o. Professor der Chemie, an der Staats- universitat zu Gent. ( Translation) “ The remarkable discovery just made by Wanklyn, of the formation of Propionic Acid by the action of Carbonic Acid upon Sodium-ethyl shows plainly that in both acids (acetic and propionic) the radicals of Carbonic Acid must exist along with the radical methyl or ethyl.” See Erste Lieferung, paragraph 260.
