They are not necessary to life in itself, hence they enter as food and become transformed into protoplasm. The lowest forms of life with which we are acquainted are nothing but simple pieces of protoplasm and yet they have all the appearance of living objects. But in what consist these signs of life which are common to all living objects?
Is it, then, astonishing that they should adapt themselves so readily to the position which they know it is for the social welfare of the community, and hence of themselves, that they should occupy, and that they should know that they will want a cavity in their thighs and a proboscis, and hence make such implements out of their protoplasm as readily as they make their wings?
There is no difficulty in imagining the structure of our nervous system to be a priori, in regard to the excitements which are propagated in it. A nerve cell is formed, with its protoplasm, its nucleus and its nucleoli before being irritated; its properties precede its functions.
All scientists are busy with their priestly avocations, out of which proceed investigations into protoplasm, the spectral analyses of stars, and so on.
But add a touch of chemistry, and he was interested. Chemistry leads up to life. He said he did not think he would feel threatened or insulted if a chemist should take his protoplasm, or mix his hydrogen, oxygen, and carbon, and make an animalcule incontestably swimming and jumping before his eyes. It would be only evidence of a new degree of power over matter which man had attained to.
So much for the conclusions in regard to the larger aspect of life taken as a whole which must follow from confining life to protoplasm; but there is another aspect that, namely, which regards the individual.
It is a fair question whether the protoplasm of those simplest forms of life, which people an immense extent of the bottom of the sea, would not outweigh that of all the higher living beings which inhabit the land put together. And in ancient times, no less than at the present day, such living beings as these have been the greatest of rock builders.
So it simply sends down the long tube, which grows fast, pushing along through the style, whose tissues are rather loose, and carrying with it the only valuable part of the pollen grain, its living protoplasm. No ovule can possibly grow into a grain without this tiny bit of pollen.
A minute protoplasm, a jelly-like substance, and if you examine it with a powerful microscope you will hardly find any difference between it and the proto-plasmic germ of a dog, or of a cat, or of a tree. It is smaller than a pin's head.
Each man of you finds Sunday quite different, yet each man of you can only find one thing to compare him to the universe itself. Bull finds him like the earth in spring, Gogol like the sun at noonday. The Secretary is reminded of the shapeless protoplasm, and the Inspector of the carelessness of virgin forests. The Professor says he is like a changing landscape.
