"Protoplasm" Quotes from Famous Books



... to animal minds, the study of the first beginnings of nerve action, and the analysis of instinct, all due largely to Darwin's prominent disciple, Romanes, together with the immensely fuller knowledge of molecular physics, of protoplasm, and of brain function, acquired in the years since Darwin wrote, have sufficed to place these questions on a much more secure basis. But the collection of facts made by him, and the suggestive remarks he everywhere makes, render his book of permanent ...

... vary according to the amount of acid or alkali in the sap. Try the effect of immersing a blue morning glory in an acid solution, or a deep pink one in an alkaline solution. One theory to account for the presence of color is that it exists to screen the plant's protoplasm from light; that it has a physiological function with which insects have nothing whatever to do; and that by its presence the temperature is raised and the plant is protected from cold. Every one who has handled the colorless Indian pipe ...

... brush before. But he had also to learn to breathe, and digest, and circulate his blood. Although his father and mother were fully grown adults when he was conceived, he was not conceived or even born fully grown: he had to go back and begin as a speck of protoplasm, and to struggle through an embryonic lifetime, during part of which he was indistinguishable from an embryonic dog, and had neither a skull nor a backbone. When he at last acquired these articles, he was for some time doubtful whether he was ...
— Back to Methuselah • George Bernard Shaw

... speculative young man of our own day is likely to puzzle himself, or exercise the patience of his neighbour in a railway carriage, of his dog, or even of a Chinese; though the questions we are apt to tear to pieces, organism and environment, or protoplasm perhaps, or evolution, or the Zeit-geist and its doings, may, in their turn, come to seem quite as lifeless and unendurable. As the theological heresy of one age sometimes becomes the mere commonplace of the next, ...

... the idea that the forces which rule in the realm of living things are not different from the forces that we know in the inanimate world. He has made some very striking and arresting experiments with protoplasm and chemical stimuli and opened a new field of problems in biology. If the physical universe can be so increasingly explored, shall not the spiritual universe be also penetrated by the spiritual powers ...

... more than his chance—more than many chances. He was the kind of protoplasm that could not endure life, that carried in itself the seed of decay,—yet—yet—" She raised her pale face with the luminous eyes and said softly: "Sometimes I wonder if it had to be. When I look at little Ned and see how health is coming ...

... this special purpose, I have not the least doubt, from the observations of Delpino, and more especially from those of Mr. Belt on Acacia sphaerocephala, and on passion-flowers. This acacia likewise produces, as an additional attraction to ants, small bodies containing much oil and protoplasm, and analogous bodies are developed by a Cecropia for the same purpose, as described by Fritz Muller. (10/50. Mr. Belt 'The Naturalist in Nicaragua' 1874 page 218, has given a most interesting account of the paramount importance of ants as defenders of the above Acacia. ...

... nobody explains; which, indeed, nobody seems to find difficult. Yet the difficulty is insuperable. Even if we take refuge with Wilamowitz in the idea that the Cyclic and Homeric poems were at first mere protoplasm of lays of many ages, and that they were all compiled, say in the sixth century, into so many narratives, we come no nearer to explaining why the tone, taste, and ideas of two such narratives— Illiad and Odyssey—are confessedly distinct from the tone, taste, ...
— Homer and His Age • Andrew Lang

... itself is arduous. After all is said, it is not quite the same task to examine and classify either protoplasm or the most highly organized forms of nature, that it is to analyze and understand the mysterious workings of the heart, the intricacies of conscience and conduct, the possibilities of spiritual development or of moral ...

... from meeting one another in a healthy state. But in most cases it is probable that the sterility is due to some other cause. It is not inconceivable that definite differences in chemical composition render the protoplasm of one species toxic to the gametes of the other, and if this is so it is not impossible that we may some day be able to express these differences in terms of Mendelian factors. The very nature of the case makes it one of extreme difficulty for experimental ...

... hydathodes through the vascular fibres, the cell walls of the hydathodes are still adapted for filtration, and yet they do not filter. Hence some other factor must join itself to the physico-mechanical process of filtration and affect or destroy it, and this factor can be found only in the protoplasm, the vital element of the cells; for we know that the sublimate acts with pernicious effect on it and in such a manner that it destroys its entire power of reaction; it kills ...

... servants with a perfect Babel of names—and Great Britain was grandly represented. Those three superhuman men, who had each had a peep behind the veil of creation, and discovered the mystery of life, attended the party and became centres of three circles—the circle that believed in "protoplasm," the circle that believed in "bioplasm," and the circle that believed in "atomized charges of electricity, conducted into the system by the oxygen of respiration." Lectures and demonstrations went ...
