What the disease was or how it was spread is unknown and unknowable at this late date. Virus or bacterium, amoeba or fungus whatever it was, it struck. Symptoms: Lassitude, weariness, weakness, and pain. Signs: Great, ulcerous, wartlike, blood-filled blisters that grew rapidly over the body.
But the amount of oxygen required, and of waste to be removed is proportional to the mass; for every particle of protoplasm requires food and oxygen, and produces waste. The particles of protoplasm in our new, larger amoeba can therefore receive only half as much oxygen as before, and rid themselves of their waste only half as fast.
The first of these instruments enabled the early observers to see some of the larger and more conspicuous members of the group and each improvement of the microscope has enabled us to see more and more of them and to study in detail not only the structure but to follow the life-history of many of them. The Amoeba.
And there are other worlds whose life-cycle has been run; where intelligent life has ceased: where world-disintegration has set in. For this is in accordance with the universal law of Growth and Decay a law that exempts neither the one-celled amoeba, nor the complex Solar system whirling yonder in Infinite space.
The repetition, therefore, of its developmental stages by any offspring must be regarded as something which the embryo repeating them has already done once, in the person of one or other parent; and if once, then, as many times as there have been generations between any given embryo now repeating it, and the point in life from which we started say, for example, the amoeba.
Hence the comparative study and classification of modern races establishes a scale of social grades which corresponds with the order of their historic succession, just as in a larger way the complete series of comparative anatomy from Amoeba to man displays the order of evolution from unicellular beginnings to the present culminating types.
It is simply a "living drop of glue," which eats, digests, receives impressions and responds thereto, and reproduces itself. This tiny glue-drop performs virtually the same life functions as do the higher complex forms of living things. Which is the greater "miracle" the Moneron or Man? A slight step upward from the Moneron brings us to the Amoeba.
Each possesses the power of adapting its organization to the variations of the external world; and it is this power, called into activity by cosmic changes, which has enabled the simple zoophytes of the primitive world to climb to higher and higher stages of organization, and has brought endless variety into nature. There you have your evolution of Man from the amoeba all complete whilst Nelson was still alive on the seas.
After all, what is every man? he talked on; 'a horde of ghosts like a Chinese nest of boxes oaks that were acorns that were oaks. Death lies behind us, not in front in our ancestors, back and back, until "Until?" Lawford managed to remark. 'Ah, that settles me again. Don't they call it an amoeba? But really I am abjectly ignorant of all that kind of stuff.
Yet witness the motly products of evolution: Man, ape, elephant, skunk, scorpion, lizard, lark, toad, lobster, louse, flea, amoeba, hookworm, and countless microscopic animals; also, the palm, lily, melon, maize, mushroom, thistle, cactus, microscopic bacilli, etc. All developed from one germ, all in some way related.
