Excerpt from Journal of the Portland Society or Natural History, Vol. 1: No; 1 Nothing can be more artificial than a classification of mollusca based on the shell alone, or even on any single organ or portion of the animal. Now, true classification is not artificial; it is the revelation of a natural order. All minor peculiarities play their part only in the grand whole, and therefore we have no right to cull out special points here and there for the arbitrary establishment of convenient groupings. In the following synoptical table I have grouped the species together under certain generic, sub-family. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Over centuries, discoveries of fossil bones spawned legends of monsters such as giants and dragons. As the field of earth sciences matured during the 19th century, early fossilists gained understanding of prehistoric creatures such as Tyrannosaurus, Triceratops and Stegosaurus. This historical study examines how these genuine beasts morphed in the public imagination into mythical, powerful engines of destruction and harbingers of cataclysm, taking their place in popular culture, film, and literature as symbols of "lost worlds" where time stands still.
How do you tailor education to the learning needs of adults? Do they learn differently from children? How does their life experience inform their learning processes? These were the questions at the heart of Malcolm Knowles’ pioneering theory of andragogy which transformed education theory in the 1970s. The resulting principles of a self-directed, experiential, problem-centred approach to learning have been hugely influential and are still the basis of the learning practices we use today. Understanding these principles is the cornerstone of increasing motivation and enabling adult learners to achieve. The 9th edition of The Adult Learner has been revised to include: Updates to the book to reflect the very latest advancements in the field. The addition of two new chapters on diversity and inclusion in adult learning, and andragogy and the online adult learner. An updated supporting website. This website for the 9th edition of The Adult Learner will provide basic instructor aids including a PowerPoint presentation for each chapter. Revisions throughout to make it more readable and relevant to your practices. If you are a researcher, practitioner, or student in education, an adult learning practitioner, training manager, or involved in human resource development, this is the definitive book in adult learning you should not be without.
Excerpt from Bulletins of the Zoological Society of San Diego, October 15, 1941, Vol. 17: Four Papers on the Application of Statistical Methods to Herpetological Problems The tapering bodies of most species of snakes are usually correlated with changes in the number of dorsal scale rows. In order to discuss the Shape of the dispersion curve of this character it is necessary to define the particular count which is to be used as a basis of investigation. In most taxonomic work either the number of rows at mid-body is cited, or the number at the neck, at mid-body, and just before the vent. There are four types of suppression (or lack of suppression) of scale rows between the neck and the vent: (1) a constant number; (2) a con stant number from neck to mid-body, followed by a decrease to the vent; (3) a continuously decreasing number from neck to vent; (4) an increase from neck (at its point of least diameter) to mid-body, followed by a decrease toward the vent. While many species, and even genera, adhere to only one of these methods, others may follow two or more, since, after all, there is no very sharp line between them. In fact, there is not entire agreement as to the definitions of the three points at which the rows are to be counted; usually they are (1) on the neck one head-length posterior to the hinge of the jaw; (2) at mid-body half-way between the head and vent; and (3) a short distance anterior to the vent, to avoid the irregularities involved in the considerable diminution in body diameter at that point.
