    cold, coagulates; one part of it adhering together in a folid mafs, and, the other feparating there¬ from, remains fluid. If you cut off the mucro of a live heart, and turn the fmall end upwards, the blood is drove into the ventricles of the heart, upon the contradion of the auricles, but without any ebullition, or fermentation. This is more confpicuous a little before the death of the part; and the fame phenomena appear in the blood contained in the left ventricle. If a thermofcope be put into a live heart, it difcovers no more heat there than in another part. The chyle, in the thoracic dud, appears to have a fea-falt taft, or that which was moft predominant in the food. If received in a veffel, and mixed with different falts, it feldom, or never ferments; and, by it felf, it neither fer¬ ments, nor bubbles ,• neither is it perceived to do fo in the thoracic dud, when mixed with the blood, whether in the fubclavian vein, the auricles or ventricles of the heart; nay, if a ligature be applied to the axillary vein, be¬ fore it reaches the cava, and another betwixt that and the valve, there is no fermentation in the intermediate fpace. The lympha of the conglobate glands, fepara- ted from the arterial blood, mixed with the chyle, appears, by the fame experiments, to be homoge¬ neous, and of the fame nature and difpofl- ticn therewith. It, therefore, makes no ebul¬ lition, fermentation, or effervefcence in the heart. In regard of which mufcle, or the fluids therein contain’d, there are no confidera- ble effeds perceivable; no ebullition, fermenta¬ tion, or effervefcence: neither can the heat of the heart, as a /lew caiife, work any alteration in
