Sinopsis
Excerpt from Science Progress, Vol. 2
Martin made most of his observations on dogs, but obtained confirmatory results on other animals (cats and rabbits). He found that different doses produced different results. Immediately after the introduction of the venom the coagulability of the blood increases; and this increase in the case of moderate or large doses (more than 00001 gramme per kilo. Of body weight) culminates in intravascular clotting of greater or less extent. The injection of smaller doses produces a transient phase of increased coagulability, but after two minutes this is succeeded by a negative phase the blood drawn either fails to clot at all, or does so only after the lapse of several hours. The thrombosis occurs more readily in venous than arterial blood, and is frequently confined to the portal area.

Excerpt from Science Progress, Vol. 2
The most important class of chemical substances with which the physiologist has to deal is that of the proteids. Their importance arises from the fact that they form the most essential of the constituents of a diet, and the most constant and abundant of the materials obtainable from protoplasm and living structures generally. In spite of this, however, we know practically nothing of their chemical constitution. The physical properties of the proteids, their identification by chemical tests, their subdivision into classes according to their solubilities, and the products of their decomposition have all been pretty thoroughly studied; there also exist various theories of the way in which their molecule is built up; but there is nothing certain at present. One of the greatest feats in chemical science will be the synthesis of albumin; but until this is done our knowledge of that overwhelmingly important substance must remain nebulous, and advance in physiological chemistry be hindered.
Not the least strange of the many puzzling facts in connection with the proteids is that many of them are poisonous. The poisonous proteids are not distinguishable by any well-marked chemical or physical properties from the non-poisonous or food proteids.

Paperback. Condición: New. Print on Demand. This book explores the pivotal role of algae in constructing and shaping rock formations throughout geological history. The author uncovers the surprising fact that many rock structures once thought to be inorganic are actually the result of algal growth and accumulation. Expanding our knowledge of these ancient rock-building organisms, the book examines various types of algae, including calcareous and non-calcareous forms, and discusses their impact on the formation of oolites, limestones, and other geological features. By shedding light on the hidden world of algae in rock formation, the author reveals the remarkable contributions of these humble organisms to the shaping of our planet's geological foundations. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781330382110_0
