"Great Scot!" "This coccus, my dear friend, increases and multiplies under certain conditions. It exacts a highly lacerated condition of the mucous membrane into which it burrows. Fortunately it is rare; fortunately, also, it is seldom found in water which has filtered through diatomaceous earth; for these fossilised deposits are only found here and there, and, as a rule, not near water."
The swirl of the ship's wash brought diatomaceous scum from the sides of this ice. The water became thick with diatoms at 9 a.m., and I ordered a cast to be made. No bottom was found at 210 fathoms. The 'Endurance' continued to advance southward through loose pack that morning. We saw the spouts of numerous whales and noticed some hundreds of crab-eaters lying on the floes.
The silicious particles which constitute this mud, are derived, in part, from the diatomaceous plants and radiolarian animals which throng the surface, and, in part, from the spicula of sponges which live at the bottom.
Many substances so used are not sticky and let moisture in through the joints. Where a smooth surface is required, it is readily obtained by dusting on a little talc. It can also be given a coat of japan on the outside. American Electrician. HOW TO CLEAN DIATOMS. As a general rule, we may say that every specimen of diatomaceous earth or rock needs a special treatment.
"I made a microscopical examination of the water in your new spring, which rises, I venture to remind you, through soil which is undoubtedly diatomaceous." "That sounds awful." "Diatoms in a fossilised condition are silicious, and they are to be found in Virginia, in Bermuda, and here." "Professor, I am an ignoramus."
I allude to the shores of the Victoria Barrier, along whose coast the soundings examined were invariably charged with diatomaceous remains, constituting a bank which stretches 200 miles north from the base of Victoria Barrier, while the average depth of water above it is 300 fathoms, or 1,800 feet.
Dickie, of Aberdeen, sent these materials to Ehrenberg, who made out that the residuum of the melted ice consisted for the most part of the silicious cases of diatomaceous plants, and of the silicious spicula of sponges; while, mixed with these, were a certain number of the equally silicious skeletons of those low animal organisms, which were termed Polycistineoe by Ehrenberg, but are now known as Radiolaria.
"Then it is my duty to inform you that the man or woman who drinks water from that spring is swallowing millions of tiny flint knives, hard as diamond dust indeed, diatomaceous earth is used commercially as a polishing powder." "You mean that if we drink that water we shall be polished off?" The Professor glared.
Atolls, or Coral Islands Their strange Appearance Their Connexion with Volcanoes Their Mode of Formation Antarctic Volcanoes Diatomaceous Deposits To the southward of the Sandwich Islands, on the other side of the equator, there is a large group of islands in the Pacific, which have a very peculiar appearance. They are called Atolls or Coral Islands.
The proximity of this Diatomaceous bed to Mount Erebus would easily explain how these minute shells might be found abundant in the fine dust ejected from that volcano.
