No coagulation will probably take place. It is more difficult to coagulate boiled milk with rennet than unboiled milk. Experiment 51. Test fresh milk with red litmus paper; it should turn the paper pale blue, showing that it is slightly alkaline. Place aside for a day or two, and then test with blue litmus paper; it will be found to be acid.
If allowed to stand in a test-tube it does not coagulate, but separates into two layers: the upper, transparent, straw-coloured fluid, the liquor puris or pus serum, closely resembling blood serum in its composition, but containing less protein and more cholestrol; it also contains leucin, tyrosin, and certain albumoses which prevent coagulation.
I had not the opportunity to try if this urine would coagulate over the fire, when part of it was evaporated, which I imagine would be the criterion of this kind of diabetes; as the mucilaginous fluid deposited in the cells and cysts of the body, which have no communication with the external air, seems to acquire, by stagnation, this property of coagulation by heat, which the secreted mucus of the intestines and bladder do not appear to possess; as I have found by experiment: and if any one should suppose this coagulable urine was separated from the blood by the kidneys, he may recollect, that in the most inflammatory diseases, in which the blood is most replete or most ready to part with the coagulable lymph, none of this appears in the urine.
Nor has a mind in such a state any way of knowing how preposterous it is. Ancient fears, reinforced by more recent fears, coagulate into a snarl of fears where anything that is dreaded is the cause of anything else that is dreaded. Generally it all culminates in the fabrication of a system of all evil, and of another which is the system of all good. Then our love of the absolute shows itself.
Solutions of these do not change colour or coagulate on boiling; ammonia changes the colour to blue or green; acid brightens the original colour, while chlorine bleaches it. =Hairs.= Human hairs must be identified and distinguished from those of the lower mammals.
The white does not coagulate in roasting or boiling, and only the yolk is eaten, but that is esteemed quite as palatable as the eggs of the common fowl. The flesh of all kinds is eaten by the Indians, who fry it in pots, and then pour it with its own oil into other vessels and permit it to cool. When thus prepared, it will keep for a long time, and can be taken out when required for use.
Mademoiselle de Corandeuil did not finish her sentence, but she put a severity into these three words which seemed to condense all the quintessence of prudery that a celibacy of sixty years could coagulate in an old maid's heart. Clemence raised her eyes to her aunt's face as if to demand an explanation. It was such a calm, steady glance that the latter could not help being impressed by it.
Heart-clots were very common, if not universally present, in the cases of ulceration of the intestinal mucous membrane; while in the uncomplicated cases of diarrhea and scurvy, the blood was fluid and did not coagulate readily, and the heart-clots and fibrinous concretions were almost universally absent.
"The weather is so bitterly cold," Hsi Ch'un consequently explained smiling, "that the glue, whose property is mainly to coagulate, cannot be moistened, so I feared that, were I to have gone on with the painting, it wouldn't be worth looking at; and I therefore put it away." "I must have it by the close of the year," dowager lady Chia laughed, "so don't idle your time away.
In those aneurysms which are a saccular bulging on one side of the artery the blood may be induced to coagulate, or may of itself deposit layer upon layer of pale clot, until the sac is obliterated.
