Amphibians and Reptiles in Captivity
In recent years the number of people interested in keeping amphibians and reptiles in captivity has grown rapidly. All too often, these same people have little knowledge of the proper care needed for their captives, nor do they know where to turn in order to learn the needs of their animals. It is the intent of the authors of this special issue to offer the proper information needed to successfully keep amphibians and reptiles in captivity. We are by no means THE experts on the subject, nor do we claim to cover all the facts. However, we do hope that enough information is furnished to answer most of the common questions asked by people. - Summary by Tom R. Johnson
Animals of the Past
Prior to the emergence of paleontology and comparative anatomy as scientific disciplines at the end of the 18th century, it was generally known that there were species of animals that had disappeared completely. The term "extinction" originally applied to the extinguishing of fires or erasing of one's debt. It was not until 1784 that the term extinction was used to denote the complete eradication of a species of living being. In 1901, Frederic A. Lucas penned an overview of vertebrate animals whose only evidence of being remained in fossil records. The book focuses primarily on vertebrate animals, from fish to mammals. - Summary by Jeffery Smith
Bird Stories From Burroughs – Sketches of Bird Life Taken From the Works of John Burroughs
This is John Burroughs' 1871 work, "Bird Stories from John Burroughs". It is a fantastic collection of short descriptions - or, sketches - of the lives and habits of many birds commonly found in the U.S.. Profusely illustrated and written in simple but beautiful language, "Bird Stories from John Burroughs" will appeal to all lovers of nature writing, and is not to be missed by fans and collectors of Burroughs' wonderful work. Contents include: "The Bluebird", "The Robin", "The Flicker", "The Cowbird", "The Chipping Sparrow", "The Chewink", "The Brown Thrasher", "The House Wren", "The Song Sparrow", etc. John Burroughs (1837 - 1921) was an American naturalist, essayist, and active member of the U.S. conservation movement. Burroughs' work was incredibly popular during his lifetime, and his legacy has lived on in the form of twelve U.S. Schools named after him, Burroughs Mountain, and the John Burroughs Association-which publicly recognizes well-written and illustrated natural history publications. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially commissioned new biography of the author.
