Not illustrated. 1879 Excerpt: ...On watching the hair, it was seen to become covered with an adherent clot so long as the coagulation is going on, whilst the part which is withdrawn after coagulation is ended is free from any such clot. This point is noticed, as well as the time of drawing the blood, and the interval between the two is assumed by M. Vierordt to be the period of coagulation. From 262 individual observations the author has found the mean time of coagulation to be 9.28 minutes, a result which is in dose agreement with that given by H. Nasse, who stated that ten minutes is the ordinary time. Venous blood obtained from the finger after a ligature had been applied coagulated much more rapidly, differing from arterial blood by an average time of three minutes. A similar acceleration was found in animals which were starved, or which had been previously bled. Numerous observations on the sick gave as a general result that in diseases which chronically affect nutrition, as phthisis, scurvy, and anamiia, there was an increased r;ite of blood coagulation; whilst improvement in nutrition frequently caused a more lengthened period to elapse before the coagulation took place, as in convalescence after croupous pneumonia. One set of observations, however, did not agree with this rule, as in convalescence after typhus fever an increase in the time of coagulation w'as not observed, and this was also the case in the increase of the nutritive powers after gastrectasia.--London Med. Record, May 15, 1879. Physiological Morcments of the Membrana Tympani, M. Gelle (Societe de Biologie, reported in Le Progres M&dicale, Oct. 26, 1878) has studied the movements of the entire tympanum by means of the graphic method. In ordinary deglutition, as in Valsalva's experiment, the tympanum is displaced. ...
