This early work by Alfred Russel Wallace was originally published in 1858 and we are now republishing it with a brand new introductory biography. 'On the Tendency of Varieties to Depart Indefinitely From the Original Type' is a short article on variation and evolutionary theory. Alfred Russel Wallace was born on 8th January 1823 in the village of Llanbadoc, in Monmouthshire, Wales. Wallace was inspired by the travelling naturalists of the day and decided to begin his exploration career collecting specimens in the Amazon rainforest. He explored the Rio Negra for four years, making notes on the peoples and languages he encountered as well as the geography, flora, and fauna. While travelling, Wallace refined his thoughts about evolution and in 1858 he outlined his theory of natural selection in an article he sent to Charles Darwin. Wallace made a huge contribution to the natural sciences and he will continue to be remembered as one of the key figures in the development of evolutionary theory.

Alfred Russel Wallace is best known as the co-originator of the theory of evolution by natural selection, an honor he shares with his contemporary Charles Darwin. Among the ten essays in this volume is his seminal paper on natural selection, "On the Tendency of Varieties to Depart Indefinitely from the Original Type," which was presented with Darwin's "On the Origin of Species" at a meeting of the Linnean Society of London in July 1858. This edition of Wallace's "Contributions to the Theory of Natural Selection" is the first entry in the Foundations of Biological Thought series published by Briar Bird Press. The series presents the pivotal works of 19th century naturalists remastered for modern readers. Meticulously edited, these volumes preserve the author's intent in design and content, including the manuscript's original annotations and amendments. In addition, revised page references and editor's notes are included throughout to retain the utility of the works for both study and reference.

The present Depression of Trade is remarkable, not so much for its intensity or for its extent—in both of which respects it has been equalled or surpassed on previous occasions, but for its persistence during the long period of eleven years. The late Professor Fawcett, in his Free Trade and Protection (p. 151), says: “The industrial depression is generally thought to have commenced in the closing months of 1874;” and during every succeeding year it has continued to be felt with more or less severity, and its remarkable persistence has been commented on by politicians and public writers. Usually a period of depression is quickly followed by one of comparative prosperity. Such a reaction has been again and again predicted in this case; but up to the present time there are no satisfactory indications that the evil days are passing away. It is evident, therefore, that we are suffering in an altogether exceptional manner, that the disease of the social organism is due to causes or combinations of causes which have not been in action on former occasions, and that the remedial agencies which have been effective on former occasions of depression have now failed us. We thus find ourselves confronted with a problem of vital importance to our well-being as a nation. We are called upon to explain why it is that, notwithstanding the exceptional advantages we possess, in an ever-increasing command over the more recondite powers of nature, an ever-increasing use of labour-saving machinery, a body of labourers whose industry and skill are proverbial, and far more complete and perfect communication with the whole world than was possessed by any previous generation—notwithstanding all these favourable conditions, which would seem to render prosperity certain, we yet find trade crippled and labour paralysed, goods of all kinds selling at unremunerative prices, yet the masses too poor to buy, and universal complaints of diminished profits and restricted markets. So long as these questions are not fully and completely answered, so long as a remedy is not found for the widespread and persistent evil which afflicts the mass of our people, our whole system of social economy, even our civilisation itself, must be accounted to be failures. It will undoubtedly be admitted that a system of society under which willing hands cannot find profitable work, and countless shops and warehouses overflowing with every necessary, comfort, and luxury, mock the longing eyes of insufficiently-clad and half-starved millions, is neither a sound nor a safe one. We may therefore expect to find that the problem of trade-depression is fundamentally the same as that of the persistence of widespread poverty and pauperism notwithstanding our rapid and continuous growth in wealth; and if this be so, its solution will assuredly furnish us with some important principles to direct the course of future legislation. The main points of a sound political programme may be one of the important results of a successful investigation into the causes which have brought about the present depression of trade.

Charles Darwin's years as a student at the University of Cambridge were some of the most important and formative of his life. Thereafter he always felt a particular affection for Cambridge. For a time he even considered a Cambridge professorship as a career and sent three of his sons there to be educated. Unfortunately the remaining traces of what Darwin actually did and experienced in Cambridge have long remained undiscovered. Consequently his day-to-day life there has remained unknown and misunderstood. This book is based on new research, including newly discovered manuscripts and Darwin publications, and gathers together recollections of those who knew Darwin as a student. This book therefore reveals Darwin's time in Cambridge in unprecedented detail.
