Nor are the benefits of mastication confined wholly to the process of digestion. It is fully believed by distinguished physiologists, that the teeth themselves will last longer for being considerably used; and they seem to be borne out in this conclusion by facts. But if this is the case, what are we to think of the importance of light to the eye, sound to the ear, employment to the hands, &c.?
Curdled blood, frozen marrow, unbeating heart ... who first discovered that this is what occurs to these organs when fear assaults the brain? Have physiologists said so, or is it a mere amateur guess at truth, another of the foolish things "they" say? In these speculations Henry's mind engaged while he stood in the black bowels of the earth and beat for entry at the world's closed door.
M. Comte, accordingly, claims the scientific cognizance of moral and intellectual phenomena exclusively for physiologists; and not only denies to Psychology, or Mental Philosophy properly so called, the character of a science, but places it, in the chimerical nature of its objects and pretensions, almost on a par with astrology.
I intended later to devote myself earnestly to the study of physiology, for without it Lotze could be but half understood; and from physiologists emanated the conflict which at that time so deeply stirred the learned world. In Gottingen especially the air seemed, as it were, filled with physiological and other questions of the natural sciences.
One of these was the prince of the physiologists of the eighteenth century, the great Haller, who contributed an elaborate history of those who had been his predecessors in unfolding the intricate mechanism of the human frame, and analysing its marvels of complex function. The other was the austere and generous Condorcet.
As the heart is essentially nothing more than an aggregation of muscles, this phenomenon was utterly puzzling and without precedent in the experience of physiologists. An impulse travelling along a motor nerve had been supposed to be able to cause a muscular contraction and to do nothing else; yet here such an impulse had exactly the opposite effect.
As every one knows, or at least as all intelligent people know, the special department in which Gibberne has gained so great and deserved a reputation among physiologists is the action of drugs upon the nervous system. Upon soporifics, sedatives, and anaesthetics he is, I am told, unequalled.
No doubt, here and there in Scripture, fire stands for a symbol of destroying power. But that is a less frequent use than that in which it stands as a symbol of life. In a very real sense life is warmth and death is cold. Is not respiration a kind of combustion? Do not physiologists tell us that?
She was then sufficiently well-developed, and had a good color; all the functions appeared to act normally, and the catamenia were fairly established. She was ambitious as well as capable, and aimed to be among the first in the school. Her temperament was what physiologists call nervous, an expression that does not denote a fidgety make, but refers to a relative activity of the nervous system.
The exercise of the lungs consists not only in their full and free expansion in breathing, but in speaking, singing, &c., and even in laughing. Physiologists also consider sneezing, coughing and crying, especially the latter, as having their advantages, in early infancy, and perhaps, in same circumstances, even afterward.
