Indefinite and structureless in the simplest of these forms, as instance again the Gregarina, the limiting membrane becomes, in higher Infusoria, definite and often complex: showing that the selection of favourable variations has had largely to do with its formation.
A portion, however, of this mud, which when wet resembled pounded chalk, was found by Professor Ehrenberg to be partly composed of siliceous-shielded infusoria. April 12th. In the morning we stood out of the lagoon on our passage to the Isle of France. I am glad we have visited these islands: such formations surely rank high amongst the wonderful objects of this world.
I comprehended instantly that, by the wondrous power of my lens, I had penetrated beyond the grosser particles of aqueous matter, beyond the realms of infusoria and protozoa, down to the original gaseous globule, into whose luminous interior I was gazing as into an almost boundless dome filled with a supernatural radiance. It was, however, no brilliant void into which I looked.
It was as if all the old political shades, that formerly fought and crowded one another within each of the two circles be it that of the Legitimists or that of the Orleanists , had been thawed out like dried infusoria by contact with water; as if they had recovered enough vitality to build their own groups and assert their own antagonisms.
Observing at Colombo that the whole area so tinged changed its position without parting with any portion of its colouring, I had some of the water brought on shore, and, on examination with the microscope, found it to be filled with infusoria, probably similar to those which have been noticed near the shores of South America, and whose abundance has imparted a name to the "Vermilion Sea" off the coast of California.
With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter. It is possible that the infusoria under the microscope do the same. No one gave a thought to the older worlds of space as sources of human danger, or thought of them only to dismiss the idea of life upon them as impossible or improbable.
Some day when science has attained to a pitch that enables us to study the natural history of hearts, when they are named and classified in genera, sub-genera, and families; into crustaceae, fossils, saurians, infusoria, or whatever it is, then, my dear fellow, it will be ascertained that there are natures as tender and fragile as flowers, that are broken by the slight bruises that some stony hearts do not even feel "

He found it composed of dry infusoria, the forms of which are found not on an African desert, but in the south-east trade-wind regions of South America." "South America, father!" exclaimed Jerry, pointing with his hand to the south-west. "How can those clouds of red dust come all the way out here in the teeth of the north-east trade-wind?"
