    Abstract: The late Professor S. I. Malyshev, who died from a cerebral haemorrhage on 9 May 1967 at the age of 83 in the train while travelling to field work, was one of the foremost European students of the Hymenoptera, in particular of the habits of solitary bees, a subject on which he had published many papers since 1908, mostly in Russian. In 1935 he published an important paper on part of his work, and I helped to edit the publication, which was in English. A few years ago some of my friends in California asked me if I could not persuade him to complete his early paper on solitary bees, offering if necessary to arrange for a translation. When I wrote to Professor Malyshev making this suggestion he no longer had the health to produce a new work, but he sent me a copy of his recent book on the evolution of the Hymenoptera which he thought might be worth trans­ lating. Sir Boris Uvarov was good enough to translate for me the chapter and section headings, and it seemed to both of us that a lot of new ground was covered in a highly original way. The explanation of the changes in behaviour that must have taken place when the simple, plant-feeding saw­ flies developed into highly specialized parasites or into industrious, food­ collecting, social insects such as the ants, bees, and wasps can well be regarded as one of the major challenges to zoologists.

    Abstract: In this book we attempt to develop the fundamental results of resistive network analysis, based upon a sound mathematical structure. The axioms upon which our development is based are Ohm's Law, Kirchhoff's Voltage Law, and Kirchhoff's Current Law. In order to state these axioms precisely, and use them in the development of our network analysis, an elaborate mathematical structure is introduced, involving concepts of graph theory, linear algebra, and one dimensional algebraic topology. The graph theory and one dimensional algebraic topology used are developed from first principles; the reader needs no background in these subjects. However, we do assume that the reader has some familiarity with elementary linear algebra. It is now stylish to teach elementary linear algebra at the sophomore college level, and we feel that the require­ ment that the reader should be familiar with elementary linear algebra is no more demanding than the usual requirement in most electrical engineering texts that the reader should be familiar with calculus. In this book, however, no calculus is needed. Although no formal training in circuit theory is needed for an understanding of the book, such experience would certainly help the reader by presenting him with familiar examples relevant to the mathematical abstractions introduced. It is our intention in this book to exhibit the effect of the topological properties of the network upon the branch voltages and branch currents, the objects of interest in network analysis.
