Introduction and Notes by R.T. Jones, Honorary Fellow of the University of York. Although the shortest of George Eliot's novels, Silas Marner is one of her most admired and loved works. It tells the sad story of the unjustly exiled Silas Marner - a handloom linen weaver of Raveloe in the agricultural heartland of England - and how he is restored to life by the unlikely means of the orphan child Eppie. Silas Marner is a tender and moving tale of sin and repentance set in a vanished rural world and holds the reader's attention until the last page as Eppie's bonds of affection for Silas are put to the test.

With an Introduction and Notes by R.T.Jones, Honorary Fellow of the University of York. The novel follows the life of its eponymous heroine, Moll Flanders, through its many vicissitudes, which include her early seduction, careers in crime and prostitution, conviction for theft and transportation to the plantations of Virginia, and her ultimate redemption and prosperity in the New World. Moll Flanders was one of the first social novels to be published in English and draws heavily on Defoe's experience of the topography and social conditions prevailing in the London of the late 17th century.

Introduction and Notes by R.T. Jones, Honorary Fellow of the University of York. This edition of the poetry of Rudyard Kipling (1865-1936) includes all the poems contained in the Definitive Edition of 1940. In his lifetime, Kipling was widely regarded as the unofficial Poet Laureate, and he was awarded the Nobel Prize for Literature in 1907. His poetry is striking for its many rhythms and popular forms of speech, and Kipling was equally at home with dramatic monologues and extended ballads. He is often thought of as glorifying war, militarism, and the British Empire, but an attentive reading of the poems does not confirm that view. This edition reprints George Orwell's hard-hitting account of Kipling's poems, first published in 1942, and generally regarded as one of the most important contributions to critical discussion of Kipling.

Sulfonium compounds have been known to the organic chemist for almost 90 years. During most of this period they remained curiosities, well suited for didactic purposes to illustrate certain similarities to ether adducts and to organic ammonium compounds. Their exploration remained largely in the academic realm, because no unusual practical applications were found in spite of a steady increase in the attention paid to them. An event that occasionally puts a class of compounds into the center of interest is the recognition of its occurrence in nature and of special biological significance. The first natural sulfonium compound was discovered less than 20 years ago, somewhat by chance rather than as the climax of some coveted biochemical problem. Gradually, however, the unique role of sulfonium compounds, especially of S-adenosyl- methionine, in enzymatic group transfer reactions such as trans- methylation was recognized, and the recent upsurge of interest has been exceptional. The present review is directed toward an interpretation of the properties and functions of biological sulfonium compounds with frequent reference to their structural chemistry. The data presented here may suggest novel or improved analytical techniques and new interpretations of the mechanism of group transfer. Furthermore, a stimulus may be derived for the design of sulfonium compound analogues. The availability of competitive analogues of biochemical key compounds has aided in the understanding of the function of virtually all metabolic intermediates, prosthetic groups of enzymes, vitamins, amino acids, and other compounds. The pattern will be similar in sulfonium biochemistry.

Mr Jones treats the main novels in chronological sequence examining with the aid of extensive quotation George Eliot's means of description and characterisation and the moral purpose of her fiction. He emphasises her appeal to the inner life of her readers, as exemplified in her frequent use of such phrases as 'Have we not all...' George Eliot assumes that no human act or emotion is entirely unconnected with what we have all done or felt at some time. Her sympathy with human weakness often carries her to the point where she has difficulty in reconciling her tolerance with her moral purpose. This book gives a useful introduction to George Eliot's novels. As in the other books in the series British Authors: Introductory Critical Studies, the author assesses his subject simply and clearly, using as a basis the internal evidence of the novels themselves rather than biographical detail.

Aerodynamic theory was not prepared to offer assistance in the early development of the airplane. The scientific community, most qualified for action at the forefront of human endeavor, often turns out in practice to be surprisingly conservative. It is recorded that Lord Rayleigh expressed "not the smallest molecule of faith in aerial navigation, except by balloon." It was not until experiments such as those of Lilienthal and Langley and the successful powered flights of the Wright brothers that correct theories for the aerodynamic action of wings were developed. Following the successful demonstrations of the Wright brothers, aerodynamic theory developed rapidly, primarily in European laboratories. These developments we associate with the names Joukowsky, Kutta, Prandtl and his students, Munk, Betz, and Von Karman. It should not be forgotten that the writings of F. W. Lanchester provide many of the physical insights that were elaborated in these mathematical theories. Throughout World War I, these developments in aerodynamic theory remained virtually unknown in the U.S. However, in the early 1920's, the U.S. National Advisory Committee for Aeronautics undertook to translate or otherwise make available important works on aerodynamic theory in the form of NACA Technical Reports, Notes, and Memoranda, and to encourage similar effort in its own laboratory. At the present time, many of these old NACA documents are no longer readily available and it seems worthwhile to collect the most important early works under the title "Classical Aerodynamics." In most cases, the theories are explained in the author's own words and often with a degree of clarity unequalled in later interpretations. R. T.
