The Hague, The Netherlands: Mouton & Co., 1972 Printed Pages: 52. Janua Linguarum Series Minor: 152.. First Edition. Paperback. Fine/Fair. 15 Cms x 23 Cms., Mouton & Co., 1972, 3.5, North Melbourne: Australian Scholarly Publishing. 2020. MINT - a NEW copy. Illustrated with Black and White Photographs. xiv, 295 pages. The 20th-century anatomists Grafton Elliot Smith, Frederic Wood Jones and Arthur Keith travelled the globe collecting, cataloguing and constructing morphologies of the biological world with the aim of weaving these into a new vision of bio-ecology that links humans to their deep past as well as their evolutionary niche. Their version of human development and history profoundly influenced public opinion as they wrote prolifically for the press; they published bestsellers on human origins and evolution; they spoke eloquently at public meetings and on the radio. They wanted their anatomical insight to shape public policy. And by changing popular views of race and environment, they moulded attitudes as to what it meant to be human in a post-Darwinian world—thus providing a potent critique of racism. Robust, professional packaging and tracking provided for all parcels. . New. 1st Edition. Trade Paperback., Australian Scholarly Publishing, 2020, 6, Discovery Publishing House Pvt. Ltd., 2005. Hardcover. New. The present title ""Biology of Coelenterata"" A is a compilation work and embodies a fairly comprehensive treatment of the fundamental facts and aspects of morphology, anatomy, and Psychology of various types of coelenterates. It is an indispensable text meeting complete requirement of undergraduate and postgraduate students of Biology. The Purpose of this book is to provide students an authoritative and upto date text in a very simple way, easy to grasp by those who do not have strong background of this subject. Much emphasis has been given on the Anatomical studies of selected coelenterates. Ecological aspects have also been dealt with in sufficient details. Contents, 1.

Stanford.: Stanford UP. 1990.. Five black and white line maps, several black and white photographic illustrations and line illustrations, xiii + 366 pp, appendices, index, dustjacket. "In this ethnographic study of the small mountain village of Huta Ginjang in the Samosir area of northern Sumatra, the author pursues three main themes: the role of rice in the Batak economy, the ritual significance and political economy of feasting, and the cultural ecology of dry- and flooded-field rice-growing. After introductory chapters present the environmental and historical background of the Samosir region, the author describes the socio-cultural base on which its agricultural economy rests: indigenous political and religious institutions, concepts of patrilineal descent and marriage alliance, and, most importantly, the ideology of the feasting system."
