Book Description
A country uncommonly rich in plants, animals, and natural habitats, the Socialist Republic of Vietnam shelters a significant portion of the world’s biological diversity, including rare and unique organisms and an unusual mixture of tropical and temperate species. This book is the first comprehensive account of Vietnam’s natural history in English. Illustrated with maps, photographs, and thirty-five original watercolor illustrations, the book offers a complete tour of the country’s plants and animals along with a full discussion of the factors shaping their evolution and distribution. Separate chapters focus on northern, central, and southern Vietnam, regions that encompass tropics, subtropics, mountains, lowlands, wetland and river regions, delta and coastal areas, and offshore islands. The authors provide detailed descriptions of key natural areas to visit, where a traveler might explore limestone caves or glimpse some of the country’s twenty-seven monkey and ape species and more than 850 bird species. The book also explores the long history of humans in the country, including the impact of the Vietnam-American War on plants and animals, and describes current efforts to conserve Vietnam’s complex, fragile, and widely threatened biodiversity.

Book Description
Excerpt from The Standard Natural History, Vol. 5: Mammals In the beginning of the third volume of tills series we have a general account of the anatomy and physiology of the branch of Vertebrata; and here, as an introduction to the class of Mammals, we need only to refer very briefly to some of the special diagnostic characters which separate this group from the other divisions of backboned animals. In this account we have intentionally omitted those features which are common to all ertebrates, and all description of physiological phenomena which, as explained in the ordinary school text-books of human physiology, will apply as well to the whole class of mammals as to man. The Mammalia, the highest class of the animal kingdom, is more distinctly marked off from all other groups than are many of the classes considered in the preceding volumes. While there frequently exists a doubt as to the proper boundaries of some of the lower groups, or their relative importance in the scale of perfection, no such hesitancy is felt regarding the limits or the grade of the mammalia. Even within the limits of the class the orders are all well defined, and in most cases their relative rank is pretty well settled. This superiority of the mammalia over all other classes of the animal kingdom does not imply that every organ is more perfect or better adapted to its purpose, or that every individual is really higher; but that when we come to regard the totality of the organization, and the setting apart of portions of the body for some specific purpose, resulting in an increased differention of organs and an increased complexity of the organism, upon which alone the relative rank of animal rests, the higher rank is at once evident. Thus the human eye, far from being the perfect organ described in some works of a teleological tendency, is less perfect than that of the eagle in many respects, and yet no one would think on this account of placing the bird of prey higher than man. Like all vertebrates, the mammals never have more than two pairs of limbs, but with the exception of some of the aquatic forms (whale, etc.), these two pairs are always present, whence the name in frequent use for the class - quadrupeds. The anterior pair of limbs are never absent in the group. Except in a few forms, to be noted below, the body is covered with hair. The mouth is usually armed with teeth. The heart is four-chambered, and the circulation is complete. The blood is warm and contains non-nucleated red corpuscles. The body cavity is divided into two portions by a transverse muscle, the diaphragm, or "midriff," the anterior portion being called the pleural, and the posterior, or abdominal portion, the peritoneal cavity. The young are born alive, and are afterward nourished by milk, secreted by milkglands (mammce), whence the name of the class.

Book Description
Excerpt from The Standard Natural History, Vol. 1 In so far as this is a process of growth, accompanied by the assumption of a defi nite form, it might be compared with the growth of a crystal of salt in brine; but, on closer examination, it turns out to be something very different. For the crystal of salt grows by taking to itself the salt contained in the brine, which is added to its exterior; whereas the plant grows by addition to its interior; and there is not a trace of the characteristic compounds of the plant's body, albumen, gluten, starch, or cellulose, or fat, in the soil, or in the water, or in the air. Yet the plant creates nothing, and therefore the matter of the proteids and amy loids and fats which it contains must be supplied to it, and simply manufactured, or combined in new fashions, in the body of the plant.
