Sorry, no etymologies found.
Let us suppose these teachers to have reached the standpoint of the scientist who, half blind, still watches through his microscope the spontaneous movements of some particular infusory animalcule.
There are perhaps more than a million species of plants and animals, exclusive of the microscopic and infusory animalcules, now inhabiting the terraqueous globe, so that if only one of these were to become extinct annually, and one new one were to be every year called into being, much more than a million of years might be required to bring about a complete revolution of organic life.
I find it hard to believe that an infusory animalcule,
Without uncovering what does not concern us, or counting how many species of parasites hang on a bombyx; or groping after intestinal parasites, or infusory biters, or the obscurities of alternate generation; -- the forms of the shark, the labrus, the jaw of the sea-wolf paved with crushing teeth, the weapons of the grampus, and other warriors hidden in the sea, -- are hints of ferocity in the interiors of nature.
Polygastrica (infusory animalcules); Acalephae (sea-blubbers); and
Suppositions, at one time pretty generally entertained, as to the production of infusory animalcula apart from ova, have been pronounced by Professor Owen, in conformity with the result of his recent researches into the various modes of reproduction with which nature has provided these animals, to be “quite gratuitous.”
These germs, multiplying themselves by fissiparous generation, will constitute a stock of animals of a low type, such as a tribe of infusory animalcules.
In view of facts like these, we may surely say, that the existence of the infusory animalcules, and even of the entozoa, is conceivable, supposing they could only have been produced by parents of their own kind, and without having recourse to the anomalous and hypothetical doctrine of equivocal generation.
Some sea-plants, zoöphytes, infusory animalcules, and a few of the molluscous tribe, all low down in the order of being, but important from their immense numbers and joint action, commenced their work of absorbing the carbonic acid with which the air was overcharged, and building up vast piers and mounds of stone from their own remains.
Then it seems reasonable to believe, that the improved observations of future times will clear up the only remaining difficulty, and show how the infusory animalcules also are generated from beings of their own kind.
