Book excerpt: Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1904-1906, Vol. 46 The literature of Bolca fishes is extensive, and material from the typical locality has become distributed throughout the principal museums of the world. Nevertheless, the authentic specimens which have served either for the establishment of Species, or for extending our knowledge in regard to them, are preserved in comparatively few in stitutions. These are the only reliable standards we have to refer to in cases where the synonymy is confused; and as such cases are numerous, it is of importance to systematists to know where these standards are preserved and may be consulted for study. In the sequel, therefore, a list is given of all the type and figured specimens belonging to the largest single collection of Bolca fishes which at present exists. III the following brief historical summary it is hoped that some facts have been brought together relating to the study of this fauna which shall be of service to investigators.

Book excerpt: Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1890-1891, Vol. 20 The method of staining nerve-fibres which I have employed consists of a modified use of Weigert's haematoxylin. The tissue which was stained by this method was for the most part killed in hot water, although I have also successfully stained nerve-fibres which were killed in chromic acid and Kleinenberg's picro-sulphuric acid. Sections of the optic nerve which had been mounted on the slide and carried into water were treated for about half a minute with an aqueous solution of potassic hydrate 11670. They were then thoroughly rinsed in distilled water and transferred to Weigert's haematoxylin. Here they remained for about three hours at a temperature of 50 C. They were then rinsed again in distilled water, carried through the grades of alcohol, and after being dehydrated with alcohol of about they were cleared in turpentine and mounted in benzole balsam. Each nerve-fibre when so treated had a distinct blue-gray outline. The sections do not over stain even when they are kept in the dye for a prolonged period, and there is of course no subsequent decoloring. This method yields fair results when applied to nerves from any part of the lobster's body, but it is especially successful in treating that portion of the optic nerve which intervenes between the retina and the optic ganglion.

Book excerpt: Excerpt from Bulletin of the Museum of Comparative Zoölogy at Harvard College, in Cambridge, 1898-1899, Vol. 32 Clusters of nematocysts are found in the numerous wart-like pro tuberances (figs. 24 and 29, Plates X. And XI.) which are thickly scattered over the exumbrella surface of the disk, the palps, and the tentacles. These protuberances are thickly clustered near the centre of the disk, where they appear as little hemispherical projections above the general surface near the outer edges of the disk, however, they are elongate in' shape, and at the extreme edge they are again hemispherical (see Figs. 19, 26, 28, and If a weak solution of picric acid in 50% alcohol is allowed to permeate the sea water in which the medusa is living the nematocysts are exploded with great energy. Ordinarily they then present the appearance shown in Figure 21, Plate IX., but occasionally one finds one resembling that shown in Figure 22, where the main shaft of the thread is tightly coiled in a right-handed helix, and a small ellipsoidal mass of protoplasm (p) is borne upon the free extremity. It is very difficult to imagine how such a thread could be turned outward in the ordinary manner, and it is probable that the extreme stimulation caused by the picric acid produced an abnormal discharge of the nematocysts. The nematocysts which exhibited this peculiar structure were invariably immature in development, and were only about one tenth as numerous as the ordinary normal ones.

Download or read book Resurrection Science written by M. R. O'Connor and published by Macmillan + ORM. This book was released on 2015-09-15 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: **A Library Journal Best Book of 2015 ** **A Christian Science Monitor Top Ten Book of September** In a world dominated by people and rapid climate change, species large and small are increasingly vulnerable to extinction. In Resurrection Science, journalist M. R. O'Connor explores the extreme measures scientists are taking to try and save them, from captive breeding and genetic management to de-extinction. Paradoxically, the more we intervene to save species, the less wild they often become. In stories of sixteenth-century galleon excavations, panther-tracking in Florida swamps, ancient African rainforests, Neanderthal tool-making, and cryogenic DNA banks, O'Connor investigates the philosophical questions of an age in which we "play god" with earth's biodiversity. Each chapter in this beautifully written book focuses on a unique species--from the charismatic northern white rhinoceros to the infamous passenger pigeon--and the people entwined in the animals' fates. Incorporating natural history and evolutionary biology with conversations with eminent ethicists, O'Connor's narrative goes to the heart of the human enterprise: What should we preserve of wilderness as we hurtle toward a future in which technology is present in nearly every aspect of our lives? How can we co-exist with species when our existence and their survival appear to be pitted against one another?
Download or read book Passionate Curiosities written by Lauren Elizabeth Talalay and published by Kelsey Museum Publications. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passionate Curiosities explores the collections held in the University of Michigan's Kelsey Museum of Archaeology through the lens of the people whose intellectual interests, financial backing, and social networks brought artifacts to Ann Arbor from the 1880s to the 1990s. Through purchases and expeditions, these individuals shaped the Museum's internationally recognized antiquities from the ancient civilizations of Greece, Rome, North Africa, Egypt, and the Near East, extensive photographic documentation of these regions from the early 1900s, and significant assemblages of early Christian and Islamic visual culture. An intriguing array of personalities--from archaeologists, missionaries, and diplomats to industrialists, bankrollers, and inventors--weave through these pages. They include Ernst Herzfeld, the eminent Orientalist who helped forge antiquities legislation in Iran; Luigi Cesnola, the rapacious harvester of Cypriot sites; Esther Van Deman, the pioneering feminist and scholar of Roman construction techniques; and Samuel Goudsmit, the renowned nuclear physicist and avid Egyptologist. World-famous dealers who established standards in antiquities connoisseurship likewise populate these sagas. Readers will encounter Edgar J. Banks, a swashbuckling purveyor of Mesopotamian antiquities and entrepreneur of biblical documentary films; Maurice Nahman, the "lion of Cairo"; and the colorful members of the Tano dealer dynasty in Egypt. This copiously illustrated book will interest general readers as well as scholars curious about the holdings of the Kelsey, early collectors and dealers, and the history of museums.

Download or read book Trust in Numbers written by Theodore M. Porter and published by Princeton University Press. This book was released on 2020-08-18 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: A foundational work on historical and social studies of quantification What accounts for the prestige of quantitative methods? The usual answer is that quantification is desirable in social investigation as a result of its successes in science. Trust in Numbers questions whether such success in the study of stars, molecules, or cells should be an attractive model for research on human societies, and examines why the natural sciences are highly quantitative in the first place. Theodore Porter argues that a better understanding of the attractions of quantification in business, government, and social research brings a fresh perspective to its role in psychology, physics, and medicine. Quantitative rigor is not inherent in science but arises from political and social pressures, and objectivity derives its impetus from cultural contexts. In a new preface, the author sheds light on the current infatuation with quantitative methods, particularly at the intersection of science and bureaucracy.

Download or read book Cultural Techniques written by Bernhard Siegert and published by Fordham Univ Press. This book was released on 2015-05-01 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a crucial shift within posthumanistic media studies, Bernhard Siegert dissolves the concept of media into a network of operations that reproduce, displace, process, and reflect the distinctions fundamental for a given culture. Cultural Techniques aims to forget our traditional understanding of media so as to redefine the concept through something more fundamental than the empiricist study of a medium’s individual or collective uses or of its cultural semantics or aesthetics. Rather, Siegert seeks to relocate media and culture on a level where the distinctions between object and performance, matter and form, human and nonhuman, sign and channel, the symbolic and the real are still in the process of becoming. The result is to turn ontology into a domain of all that is meant in German by the word Kultur. Cultural techniques comprise not only self-referential symbolic practices like reading, writing, counting, or image-making. The analysis of artifacts as cultural techniques emphasizes their ontological status as “in-betweens,” shifting from firstorder to second-order techniques, from the technical to the artistic, from object to sign, from the natural to the cultural, from the operational to the representational. Cultural Techniques ranges from seafaring, drafting, and eating to the production of the sign-signaldistinction in old and new media, to the reproduction of anthropological difference, to the study of trompe-l’oeils, grids, registers, and doors. Throughout, Siegert addresses fundamental questions of how ontological distinctions can be replaced by chains of operations that process those alleged ontological distinctions within the ontic. Grounding posthumanist theory both historically and technically, this book opens up a crucial dialogue between new German media theory and American postcybernetic discourses.

Download or read book Signs and Society written by Richard J. Parmentier and published by Indiana University Press. This book was released on 2016-10-03 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major voice in contemporary semiotic theory offers a new perspective on potent intersections of semiotic and linguistic anthropology. In Signs and Society, noted anthropologist Richard J. Parmentier demonstrates how an appreciation of signs helps us better understand human agency, meaning, and creativity. Inspired by the foundational work of C. S. Peirce and Ferdinand de Saussure, and drawing upon key insights from neighboring scholarly fields, Parmentier develops an array of innovative conceptual tools for ethnographic, historical, and literary research. Parmentier’s concepts of “transactional value,” “metapragmatic interpretant,” and “circle of semiosis,” for example, illuminate the foundations and effects of such diverse cultural forms and practices as economic exchanges on the Pacific island of Palau, Pindar’s Victory Odes in ancient Greece, and material representations of transcendence in ancient Egypt and medieval Christianity. Other studies complicate the separation of emic and etic analytical models for such cultural domains as religion, economic value, and semiotic ideology. Provocative and absorbing, these fifteen pioneering essays blaze a trail into anthropology’s future while remaining firmly rooted in its celebrated past.
