Abstract
LONDON Chemical Society, Febrùary 1.—Dr. Gilbert, president, is the chair.—The following were elected Foreign Members:—F. Beilstein, P. T. Cléve, H. Debray, E. Erlenmeyer, R. Fittig, H. Helmboltz, D. Mendeleeff Victor Meyer, Lothar Meyer. The following were elected ordinary Fellows:—H. C. Bond, C. Basu, J. Brock, A. M. Chance, J. T. Donald, H. C. Foote, W. Fox, W. R. Flett, J. A. M. Fallon, E. C. Gill, F. Guthard, J. Hunter, H. Jones, B. R. Lee, A. H. Jackson, Joowansinghi, T. Jenner, J. E. Johnson, W. W. J. Nicol, F. W. Richardson, E. S. Spencer, C. A. Serré, T. Turner, J. E. Tuit.—The following papers were read:—On derivatives of fluorene, by W. R. E. Hodgkinson and F. E. Matthews. The fluorene was crystallised five or six times from alcohol; it melted 113°; when pure, it does not fluoresce. A dibrom and monobrom derivative were obtained, and a fluorene sulphonic acid; by the action of caustic potash on the potassium sulpbonate, a trihydroxy-dipbenyl was formed; and by dropping the hydrocarbon into fused caustic potash, a dihydroxy-diphenyl was proenred.—On the action of chlorine on certain metals, by R. Cowper. As observed by Wanklyn, dry chlorine has no action upon melted sodium; the author finds that dry chlorine has no action upon Dutch metal, zinc, or magnesium; it acts veey sluwly upon silver and bismuth; tin, arsenic, and antimony are attacked rapidly, with evolution of hest.—Some notes on hydrated ferric oxide, and its behaviour with sulphuretted hydrogen, by L. T. Wright. The author found great difficulty in obtaining ferric hydrate, by precipitating the chloride with am monis, free from basic chloride. Having poured sonic ferric chloride into an excess of ammonia, he evaporated to dryness at 100°. The residue, when treated with water, gave a reddish solution which would not yield a clear filtrate, some of the iron being probably in the so-called “colloidal” condition. Such ferric hydrate is not turned black by sulphuretted hydrogen; ordinary ferric hydrate is turned black at once, and the sulphide of iron dissolves in excess of potassium cyanide, forming potassium sulphide and ferrocyanide.—On alpha cyanonaphthalene sulphonic acid, by W. K. Dntt. The author first prepared the naphthalene sulphonic acid, then distilled tbe potassium salt with dry potassium ferrocyanide, and converted the cyanonaphthalene by sulphuric hydrochlaride into the above substance.
