This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1901 edition. Excerpt: ...of proteid substances. Among these the rate of the rise of temperature is one of some importance. This was clearly shown in the work of Corin and Ansiaux2 on serum, and in that of Hewlett8 on white of egg. These observers found that if the temperature is maintained long enough below the point at which heat-coagulation is usually stated to occur, not merely opalescence, but the formation of flocculi will take place. In performing the process of fractional heat-coagulation with saline extracts of various organs and tissues, I4 have shown that in nearly all of them a proteid is present which coagulates at an extremely low temperature (45 to 50 C). This proteid is a globulin, and it appears to be as characteristic of protoplasmic structure as nucleo-proteid. Whether this proteid is the same in extracts of all tissues is uncertain, but the term cell-globulin may be provisionally employed to designate it. The next question which arises is whether the behaviour of saline extracts of cellular tissues is a trustworthy guide to teach us the condition of the proteids as they actually exist in protoplasm. As a help in answering this question, I must allude to a Bulletin de VAcad. roy de Belgique, xxi., p. 3, 1891.--' Journ. of Physiology, xiii., p. 494, 1893. 1 The papers relating to this subject are numerous, and were all published in the Journal of Physiology. A summary of them will be found in my article on the Chemistry of the Tissues and Organs in Schitfer's "Textbook of Physiology," vol. i. the work of Brodie and Richardson,5 and Vernon.6 These investigators show in the case of muscle that the shortening which occurs during heat-rigor takes place in a series of steps; the temperatures at which these steps occur are the same as those...
