Abstract
THIS volume contains a brief account of the three types of valency which are now generally recognised as definitely distinct in character. The descriptive portion is followed by thermochemical data on the heats of formation of compounds from which the thermal values for the energy required to rupture different bonds in complex molecules are calculated. These in turn are employed to elucidate the structure of numerous compounds. Some of the formulae proposed, for example, H2-C H H. for methane, H2-N-.H for ammonia, and NH-CO-NH3 for urea, are so different from those usually accepted, and the evidence advanced in favour of them is so problematical in character, that the book must be regarded as one which might be somewhat unsafe as a text-book. It does, nevertheless, contain many interesting observations on reactivity of organic compounds.
