The microscope revealed the complexity of organic tissues, the existence of minute creatures, vaguely called infusoria, and the strange inhabitants of the blood, the red and white corpuscles. ❋ James Harvey Robinson (1899)
There are certain minute animal productions called infusoria and organisms peculiar to each portion of the globe. ❋ William Henry Giles Kingston (1847)
In 1838, Christian Gottfried Ehrenberg gave a description of the finer structure of the "infusoria" but it was Ferdinad Cohn, who in 1854 first ascertained with certainty that bacteria belonged to the vegetable kingdom. ❋ 1840-1916 (1913)
It is possible that the infusoria under the microscope do the same. ❋ H. G. Wells (2009)
It proves the presence of decomposing organic matter in the water — it is full of infusoria. ❋ Unknown (2008)
Were it only by the identity of the law, the evolution of the comet in the firmament to the whirling of the infusoria in the drop of water. ❋ Unknown (2008)
Furthermore, it has been found that experiments made in the manner described above answer well with most infusions; but that if you fill the vessel with boiled milk, and then stop the neck with cotton-wool, you ‘will’ have infusoria. ❋ Unknown (2007)
These experiments, you see, all tended towards one conclusion — that the infusoria were developed from little minute spores or eggs which were constantly floating in the atmosphere, which lose their power of germination if subjected to heat. ❋ Unknown (2007)
The reports were endorsed by P.L. Smith, W. Kleinschmidt, Charles Kovar, Louis Forgeron and D. Herrero, which covered all the worlds 'authorities in the disciplines of fish parasites, ringworm, botany, infusoria and aphids. ❋ Unknown (2006)
It is like a drop of water seen through a microscope, a single drop teeming with infusoria; or a speck of cheese full of mites invisible to the naked eye. ❋ Unknown (2004)
It impresses us in the same way as a drop of water, crowded with infusoria, seen through a microscope, or a little heap of cheese-mites that would otherwise be invisible. ❋ Unknown (2004)
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. ❋ Unknown (2003)
Ehrenberg179 finds it almost wholly composed of matter which has been organised; he detects in it some siliceous-shielded, fresh-water infusoria, and no less than twenty-five different kinds of the siliceous tissue of plants, chiefly of grasses. ❋ Unknown (2003)
It is, moreover, a striking fact in the geographical distribution of the infusoria, which are well known to have very wide ranges, that all the species in this substance, although brought from the extreme southern point of Tierra del Fuego, are old, known forms. ❋ Unknown (2003)
In the case of the prawn-like crabs, their movements were as coinstantaneous as in a regiment of soldiers; but this cannot happen from anything like voluntary action with the ovules, or the confervae, nor is it probable among the infusoria. ❋ Unknown (2003)
The infusoria, with the exception of two marine species, are all inhabitants of fresh-water. ❋ Unknown (2003)
Ehrenberg4 finds that this dust consists in great part of infusoria with siliceous shields, and of the siliceous tissue of plants. ❋ Unknown (2003)
