Page 136 - The chief point in this application of histology to pathology is to obtain a recognition of the fact that the cell is really the ultimate morphological element in which there is any manifestation of life, and that we must not transfer the seat of real action to any point beyond the cell.
Page 136 - Hence it follows that the structural composition of a body of considerable size, a so-called individual, always represents a kind of social arrangement of parts, an arrangement of a social kind, in which a number of individual existences are mutually dependent, but in such a way that every element has its own special action, and, even though it derive its stimulus to activity from other parts, yet alone effects the actual performance of its duties.
Page 427 - ... from the size of a pin's head to that of a split pea, with a depressed dark scurf in the centre, surrounded with an inflamed base declining in two or three days.
Page 136 - Just as a tree constitutes a mass arranged in a definite manner, in which, in every single part, in the leaves as in the root, in the trunk as in the blossom, cells are discovered to be the ultimate elements, so is it also with the forms of animal life. Every animal presents itself as a sum of vital unities, every one of which manifests all the characteristics of life.
Page 81 - If a saturated solution of any of the common neutral salts be mixed with fresh blood, and the globules (as they have been called, but which, for the future, I shall call flat vesicles) be then examined in a microscope, the salt will...
Page 305 - nothing that lives is alive in every part," but as long as any individual part or tissue is properly called living it is only so in virtue of particles of the above-described protoplasm freely distributed among, or interwoven with the textures so closely that there is scarcely any part -5-^ of an inch in size but contains its portion of protoplasm.
Page 136 - ... intercellular substance. Whilst vegetable cells are usually in immediate contact with one another by their external secreted layers, although in such a manner that the old boundaries can still always be distinguished, we find in animal tissues that this species of arrangement is the more rare one. In the often very abundant mass of matter which lies between the cells (intermediate, intercellular substance], we are seldom able to perceive at a glance how far a given part of it belongs to one or...
Page 85 - ... layer of these bodies, such as I have described it. Thus, after the solution has been applied, the protoplasm of the blood-corpuscle without much or any alteration of form gradually contracts upon the nucleus. As the result of this contraction, it becomes entirely separated from the membraneous layer, which manifests itself in the form of a delicate double contour (Figs.
Page 304 - if the grand theory of the one true living matter was, as we have seen, hypothetically advanced by Fletcher, yet the merit of the discovery of the actual anatomical representation of it belongs to Beale, in accordance with the usual and right award of the title of discoverer to him alone who demonstrates truths by proof and fact. * * * The cardinal point in the theory of Dr. Beale is not the destruction of the completeness of the cell of Schwann as the elementary unit, for that was already accomplished...
Page 303 - Chemical analysis, accordingly, must he considered as useful in showing us, not what such matter teas composed of while it possessed vitality, but what it is composed of afterward.
