diatom ooze is the characteristic deposit in high southern latitudes.
In fact, the two pass without any sharp boundary into each other, and both present transitions to the diatom ooze.
This diatom is often found in abundance in the water supplies of cities.
The little things, he continued, delicately perforating the atmosphere as though selecting a diatom.
The diatom itself may be washed in the same way, if it is not too small.
He turns himself outside in, and makes a temporary stomach, and proceeds to digest the soft parts of the diatom.
diatom, dī′a-tom, n. one of an order of microscopic unicellular alg, of the diatomace.
Frustule, frus′tūl, n. the siliceous two-valved shell of a diatom, with its contents.
The size of the diatom, the amount of gelatine, and several other factors, will enter into the question of success or failure.
It is necessary to avoid any air current which will cause the diatom to fall from the thread.
Any of various microscopic protists of the phylum Bacillariophyta that live in both fresh and marine water, have hard bivalve shells (called frustules) composed mostly of silica, and often live in colonies. Most diatoms can perform photosynthesis. They make up a large portion of the marine plankton and are an important food source for many aquatic animals. The skeletal remains of diatoms are the main constituent of diatomite.
