Combination takes place in a few minutes with the formation of compounds which are crystalline, bard, of a high specific gravity, not easily attacked by acids, and having very high melting points. The compounds thus prepared have the following formulae Zr3B4, CrB, WB2, and Mo3B4. The authors were unable to produce the borides of copper and of 91. "The chlorine derivatives of pyridine. Part VII. Some condensation products." By W. J. Sell, M.A., F.B.S., and F. W. Dootson, M.A. A series of experiments having for their object the determination of the orientation of a compound, C10HC1UN2, which has been obtained by the action of chlorine on pyridine hydrochloride, together with certain of its derivatives (Trans., 1899, 75, 980) was described. This substance, which is the principal product of the chlorination, may be crystallised unaltered from chloroform or acetone, but if the solvent contains the hydroxy group the compound is decomposed. With benzoic and other acids it reacts, giving a theoretical yield of the acid chloride in accordance with the equation C10HC11N2 + C6H5C02H = C6H6C0C1 + C10HCl9N2O + HC1. The following formulse exhibit the relationship between the parent compound and certain of its derivatives: 92. "The diazotisation of dinitroanisidine and the constitution of the resulting product." By R. Jteldola, F.R.S., and J. V. Eyre. A Papek just published by Preyss (Bull. Soc. Ind. de Mulhouse, 1901, 70, 375) anticipates some conclusions at which the authors have arrived as the outcome of an investigation upon which they have been engaged since last October. They ar...
