الصفحة 494 - It would indeed be difficult to conceive a disposition of parts more calculated to favour the escape of water from the blood than that of the Malpighian body. A large artery breaks up in a very direct manner into a number of minute branches, each of which suddenly opens into an assemblage of vessels of far greater aggregate capacity than itself, and from which there is but one narrow exit. Hence must arise a very abrupt retardation in the velocity of the current of blood.
الصفحة 111 - There appears to be a sense of perfect intelligence conveyed from the stomach to the encephalic centre, which, in health, invariably dictates what quantity of aliment (responding to the sense of hunger, and its due satisfaction) is naturally required for the purposes of life ; and which, if noticed and properly attended to, would prove the most salutary monitor of health, and effectual preventive of, and restorative from, disease. It is not...
الصفحة 106 - ... that a well-selected vegetable diet is capable of producing, in the greatest number of individuals, the highest physical development of which they are capable, it may, on the other hand, be affirmed with equal certainty, that the substitution of a moderate proportion of animal flesh is in no way injurious ; but, so far as our evidence at present extends, this seems rather to favor the highest mental development.
الصفحة 111 - ... satiety, for this is beyond the point of healthful indulgence, and is nature's earliest indication of an abuse and overburden of her powers to replenish the system...
الصفحة 133 - The bolus as it enters the cardia turns to the left, passes the aperture, descends into the splenic extremity, and follows the great curvature towards the pyloric end. It then returns in the course of the smaller curvature, makes its appearance again at the aperture, in its descent into the great curvature, to perform similar revolutions. These revolutions are completed in from one to three minutes.
الصفحة 413 - ... possesses of accommodating itself to circumstances, it not unfrequently happens that individuals continue for years to breathe a most unwholesome atmosphere without apparently suffering from it, and thus when they at last succumb to some epidemic disease, their death is attributed solely to the latter, the previous preparation of their bodies for the reception and development of the zymotic poison being altogether overlooked.
الصفحة 719 - B. had one patient who would thus go back and correct with accuracy the writing on a whole sheet of note-paper ; but if the paper was moved from the position it had previously occupied on the table, all the corrections were on the wrong points of the paper as regarded the actual place of the writing, though on the right points as regarded its previous place.
الصفحة 352 - The venous blood and the air in the cells of the lungs have a mutual attraction, which is satisfied by the exchange of oxygen and carbonic acid that takes place through the walls of the capillaries, and when the blood has become arterialized, it no longer has any attraction for the air. Upon the very same principle therefore, the venous blood will drive the arterial before it...
الصفحة 161 - ... red and dry, at other times, pale and moist, and loses its smooth and healthy appearance ; the secretions become vitiated, greatly diminished, or entirely suppressed...
الصفحة 716 - The chief peculiarity of this state of dreaming appears to be that there is an entire suspension of volitional control over the current of thought which flows on automatically, sometimes in a uniform coherent order, but more commonly in a strangely incongruous sequence. The former is most likely to occur when the mind simply takes up the train of thought on which it had been engaged during the waking hours not long previously, and it may even happen that in consequence of the freedom from distraction...
