Böcker av Leonard Jenyns

First published in 1842, this vintage book contains part four of Charles Darwin's "The Zoology of The Voyage of H.M.S. Beagle", a fascinating and detailed account of the research he did whilst aboard the HMS Beagle between 1832 and 1836-work that played a key role in the conception of his scientific theories on evolution and natural selection. This part concentrates on the various fish that he encountered and studied around the world. Contents include: "Malacopterygii", "Lophobranchii", "Plectognathi", "Cyclostomi", "Total in the Several Orders", "Percidae", "Mullidae", "Triglidae", "Cottidae", "Scorpaenidae", "Sciaenidae", etc. Charles Robert Darwin (1809 - 1882) was an English geologist, naturalist, and biologist most famous for his contributions to the science of evolution and his book "On the Origin of Species" (1859). Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.

Although devoted to his parish, Leonard Jenyns (1800-93) combined his clerical duties with keen research into the natural world around him. His numerous publications include A Manual of British Vertebrate Animals (1835) and Observations in Natural History (1846), both of which are reissued in this series. This 1858 work is based on nineteen years of meticulous observation of Cambridgeshire weather, including trends in atmospheric pressure and precipitation. Jenyns' careful recording of his surroundings supplies the raw data for the text and many informative tables. The geological position of Swaffam Bulbeck, where most of the observations were made, is briefly discussed along with other factors bearing upon the climate of Cambridgeshire more generally. Throwing light on how meteorological observation was conducted and interpreted, the work reflects a growing interest in the topic in Victorian Britain.

Although devoted to his parish, Leonard Jenyns (1800-93) combined his clerical duties with keen research into natural history. Notably, he was offered the place on the Beagle that later went to Charles Darwin. His numerous works include A Manual of British Vertebrate Animals (1835) and Observations in Meteorology (1858), both of which are reissued in this series. First published in 1846, the present work was originally intended as a companion volume to Gilbert White's acclaimed Natural History and Antiquities of Selborne (1789), which Jenyns had copied out as a student at Eton. The product of two decades of meticulous observation of Jenyns' surroundings in eastern England, the text includes journal entries with careful records on a wide variety of wildlife, including quadrupeds, birds, reptiles, fish, insects and molluscs. Also featuring a detailed calendar of periodic phenomena, this work illuminates the rhythms and quirks of the natural world in England.

John Stevens Henslow (1796-1861), professor of botany at Cambridge University and Anglican clergyman, is best remembered for his role as a mentor to Charles Darwin. First published in 1862, this biography by Henslow's colleague and brother-in-law, Leonard Jenyns, pays tribute to a man he describes as one of the most remarkable of his time. Through vivid accounts of times spent with Henslow both in the university and on travels around Britain, he paints a portrait of a modest and conscientious man, whose pursuits were intended solely for the benefit of others. Recounting Henslow's scientific work and religious endeavours, Jenyns also explores his pioneering contribution to botany and geology, his assistance to the farmers and the poor of his parish, and the role of his faith in his work. Compiled with help from Darwin and other colleagues, Jenyns' memoir provides a unique insight into an important figure in scientific history.

Leonard Jenyns (1800-93; he changed his name late in life to benefit from a legacy), was a clergyman, and a respected naturalist and zoologist. A distinguished member of a dozen scientific societies, he was educated at Eton, and then at St John's College, Cambridge, where he graduated in 1822. During his tenure as vicar in Swaffham Bulbeck, he made important contributions to zoology, becoming one of the original members of the Zoological Society of London. In 1831, unwilling to spend years away from his parish responsibilities, he turned down the chance to travel as the naturalist on-board H.M.S. Beagle. Published in 1889, this is the second edition of Jenyns' autobiography, which he had first had privately printed. It starts with the major events of his life, then shares a series of scientific anecdotes, including his decision to recommend Darwin instead of himself as the naturalist for the Beagle voyage.
