If we take a slice of the bone and examine it, we shall find that it is very like this diagram of a section of the bone of on ostrich, though differing, of course, in some details; and if we take any part whatsoever of the tissue, and examine it, we shall find it all has a minute structure, visible only under the microscope. All these parts constitute microscopic anatomy or "Histology."
While the action of the principal cue or immediate stimulus had served to evoke the apperception-mass or context out of which this wish-phantasy was constructed, at the same moment, there was an ulterior influence at work, dictating a process of re-arrangement of the secondary images, so as to give expression to my preference for reflexology as against histology.
"I am told his allowance was four thousand dollars per annum. Histology, morphology, and aetiology are whims too costly for impecunious students. Prince must reduce his stable of hobbies." "No, he is entitled to canter as many as he likes, and the money could not be better spent than in promoting the noble work of the advancement of Science.
Special methods, therefore, were needed for this essay, and brain histology has progressed by fitful impulses, each forward jet marking the introduction of some ingenious improvement of mechanical technique, which placed a new weapon in the hands of the investigators.
I must allude to one or two points in the histology and physiology of the organs of sense. The anterior continuation of the retina beyond the ora serrata has been a subject of much discussion.
Specifically, in addition to the mental response to the external stimulus, there was a phantasy representing an imaginary wish-fulfilment: namely the desire to forsake the study of histology, with the eye-straining search through the microscope, in favor of the study of reflex-action or reflexology.
To him, too, is due the reintroduction of the art of percussion in internal disease discovered by Auenbrugger in 1761. The man who gave the greatest impetus to the study of scientific medicine at this time was Bichat, who pointed out that the pathological changes in disease were not so much in organs as in tissues. His studies laid the foundation of modern histology.
The nerve substance, in spite of its thousandfold subdivision as cells and fibres, forms, nevertheless, a united whole, which is present directly in all organs nay, as more recent histology conjectures, in each cell of the more important organs or is at least in ready communication with them by means of the living, irritable, and therefore highly conductive substance of other cells.
But while many of the sciences have so changed that the teachers of the past would hardly know them, it has not been so with the branch I teach, or, rather, with that division of it which is chiefly taught in this amphitheatre. General anatomy, or histology, on the other hand, is almost all new; it has grown up, mainly, since I began my medical studies.
Frayling followed the ray, and read the bald titles by its uncompromising clearness histology, pathology, anatomy, physiology, prophylactics, therapeutics, botany, natural history, ancient and outspoken history, not to mention the modern writers and the various philosophies. Mr.
