The shells and kernels are then separated in a winnowing machine.
My dear Mr. Hale: The beautiful shells came last night.
For a long time these shells or hulls, as they are called, were burned at oil mills for fuel, 22 tons being held equal to a cord of wood, and 43 tons to a ton of coal.
It was used in windows, though by no means exclusively, mica, alabaster and shells having been also employed.
The eggs of Cestodes consist of oval or spherical shells,(r in.
The kernel of the large-fruited variety is of very indifferent quality, but its large shells are made use of by the French as trinket cases.
The fossil shells, pottery and rude stone implements, found alike at the base and at the surface of these middens, prove that the habits of the islanders have not varied since a remote past, and lead to the belief that the Andamans were settled by their present inhabitants some time during the Pleistocene period, and certainly no later than the Neolithic age.
Protohydra occurs in oysterbanks and Monobrachium also grows on the shells of bivalves, and both these hydroids probably fish in the currents produced by the lamellibranchs.
- The genus Monobrachium is a colonyforming hydroid which grows upon the shells of bivalve molluscs, each polyp having but a single tentacle.
Thick, containing rolled fossil bones, cetacean and fish teeth, and shells of the Crag period, with nodules or pebbles of phosphatic matter derived from the London Clay, and often investing fossils from that formation.
Here they were long rolled together with the bones of large mammalia, fishes, and with the shells of molluscous creatures that lived in shells.
In thickness containing "coprolites"; these consist of phosphatized wood, bones, casts of shells, and shapeless lumps.
Fine crystals occur at Conil near Cadiz; whilst in the province of Teruel in Aragon, sulphur in a compact form replaces fresh-water shells and plant-remains, suggesting its origin from sulphur-springs.
CALIPASH and Calipee (possibly connected with carapace, the upper shell of a turtle), the gelatinous substances in the upper and lower shells, respectively, of the turtle, the calipash being of a dull greenish and the calipee of a light yellow colour.
Various species among those that are predaceous attack smaller insects, hunt in packs crustaceans larger than themselves, insert their narrow heads into snail-shells to pick out and devour the occupants, or pursue slugs and earthworms underground.
Russia, rich in salt-springs, but very poor in fossils, are now held by most Russian geologists to be Triassic. The Permian deposits contain marine shells and also remains of plants similar to those of England and Germany.
The discovery of shells (now living in the Caspian) at a distance of about 100 m.
(After Spengel.) being formed afresh on the surface of the visceral hump. It is, then, in this sense that we may speak of primary, secondary and tertiary shells in Mollusca, recognizing the fact that they may be merely phases fused by continuity of growth so as to form but one shell, or that in other cases they may be presented to us as separate individual things, in virtue of the non-development of the later phases, or in virtue of sudden changes in the activity of the mantle-surface causing the shedding FIG.
The famous manufacture of fine muslins is almost extinct, but the carving of shells, carried on from ancient times, is an important industry in the city.
In England the word "snail" in popular language is associated with Gasteropods which inhabit land or fresh water, and which possess large conspicuous spiral shells; terrestrial Gasteropods, in which the shell is rudimentary and concealed, are distinguished as "slugs."
The important exports are gums and resin, fibre, hides, ivory, ostrich feathers, coffee, ghee, livestock, gold ingots from Abyssinia and mother-of-pearl; the shells being found along the coast from Zaila to beyond Berbera.
The shells which have been found in them indicate that they belong for the most part to the Oligocene period.
The material is largely calcareous, and has probably been derived from the disintegration of the reefs, and from the shells of animals living in the shallows.
Numerous raised beaches and terraces, containing shells of marine mollusca, &c., occur along the whole coast of Greenland, and indicate that the whole of this large island has been raised, or the sea has sunk, in post-glacial times, after the inland ice covered its now icebare outskirts.
The source of the carbon of organic tissues is carbonic acid; that of the nitrogen in the proteids is the nitrates, nitrites and salts of ammonia dissolved in sea-water; the material of the shells or other skeletons is the silica, phosphate and calcium of the salts of sea-water (and, in rare cases, the salts of strontium).
All these animals have calcareous skeletons or shells of some form and they secrete the calcium from its solution as sulphate, converting it into carbonate.
" Conchiolin," the matrix of shells of the mollusca, is only slightly soluble in acids.
Of the business centre of the city is the Bernice Pauahi Bishop Museum, a fine stone building on a commanding site, and containing a large collection of Hawaiian and Polynesian relics and curios, especially Hawaiian feather-work, and notable collections of fish and of Hawaiian land shells and birds.
The group may be defined as follows: Sessile solitary Coelomata with bivalved shells usually of unequal size and arranged dorso-ventrally.
The valves are, consequently, essentially symmetrical, which is not the case with the Lamellibranchiata, - so much so, that certain Brachiopod shells were named Lampades, or lamp shells, by some early naturalists; but while such may bear a kind of resemblance to an antique Etruscan lamp, by far the larger number in no way resemble one.
The young Brachiopod in all its species is protected by an embryonic shell called the " protegulum," which sometimes persists in the umbones of the adult shells but is more usually worn off.
In the Testicardines, where no such sliding action of the valves was necessary or possible, no muscles for such an object were required, consequently none took rise from the lateral portions of the valves as in Lingula; but in an extinct group, the Trimerellidae, which seems to be somewhat intermediate in character between the Ecardines and Testicardines, have been found certain scars, which appear to have been produced by rudimentary lateral muscles, but it is doubtful (considering the shells are furnished with teeth, though but rudely developed) whether such muscles enabled the valves, as in Lingula, to move forward and backward upon each other.
In the more recent form of the hearth process the blocks of cast iron forming the sides and back of the Scottish furnace are now generally replaced in the United States by water-cooled shells (waterjackets) of cast iron.
A magnet which can be divided into simple magnetic shells, either closed or having their edges on the surface of the magnet, is called a lamellar magnet, and the magnetism is said to be distributed lamellarly.
A magnet consisting of a series of plane shells of equal strength arranged at right angles to the direction of magnetization will be uniformly magnetized.
With regard to birds and land shells the relation is much closer to the Comoros species, and the latter, of which I have collected seven species besides Rachis aldabrae, may serve to point out more than the birds the land connexion of Aldabra with the neighbouring countries."
Therein two eggs, with white, chalky shells, are commonly laid.
Hannibal is the trade centre of a rich agricultural region, and has an important lumber trade, railway shops, and manufactories of lumber, shoes, stoves, flour, cigars, lime, Portland cement and pearl buttons (made from mussel shells); the value of the city's factory products increased from $2,698,720 in 1900 to $4,442,099 in 1905, or 64.6%.
The heavy rain, which had delayed the commencement of the action, had swollen the Bistritz so as to check their advance and thus postpone the decision, whilst the mist and driving rain hid the approaching troops from the Austrian gunners, whose shells burst almost harmlessly on the sodden ground.
They had a taste for ornaments, necklaces of wood, bone and shells, worked in different designs.
The blackbird feeds chiefly on fruits, worms, the larvae of insects and snails, extracting the last from their shells by dexterously chipping them on stones; and though it is generally regarded as an enemy of the garden, it is probable that the amount of damage by it to the fruit is largely compensated for by its undoubted services as a vermin-killer.
The principal differences are the complication of the ciliated band, the absence of the excretory organ, the great lateral compression of the body, the possession of a pair of shells protecting the sides, the presence of an organ known as the "pyriform organ," and the occurrence of a sucker in a position corresponding with the depression seen between (m) and (a) in fig.
Cotton yarn and cloth, petroleum, timber and furs are among the chief imports; copper, tin, hides and tea are important exports; medicines in the shape not only of herbs and roots, but also of fossils, shells, bones, teeth and various products of the animal kingdom; and precious stones, principally jade and rubies, are among the other exports.
The houses being mostly built of a white conglomerate stone of shells and coral which forms the peninsula, gives the city when viewed from a distance a clean and handsome appearance, but on closer inspection the streets are found to be very narrow, irregular, ill-paved and filthy.
One species of Limnophilus uses small but entire leaves; another, the shells of the pondsnail Planorbis; another, pieces of stick arranged transversely with reference to the long axis of the tube.
Returning to the case of the charged body with the space around it cut up into electric cells by the tubes of force and shells of potential, it is obvious that the number of these cells is represented by the product QV, where Q is the charge and V the potential of the body in electrostatic units.
He constructed two equal condensers, each consisting of a metal ball enclosed in a hollow metal sphere, and he provided also certain hemispherical shells of shellac, sulphur, glass, resin, &c., which he could so place in one condenser between the ball and enclosing sphere that it formed a condenser with solid dielectric. He then determined the ratio of the capacities of the two condensers, one with air and the other with the solid dielectric. This gave the dielectric constant K of the material.
East of the Great Fault (already mentioned) the beds are more regular, comprising, in descending order, (a) Upper Coralline Limestone; (b) Yellow, Black or Greensand; (c) Marl or Blue Clay; (d) White, Grey and Pale Yellow Sandstone; (e) Chocolate-coloured nodules with shells, &c.; (f) Yellow Sandstone; (g) Lower Crystalline Limestone.
Corps approaching, whilst the rain of shells into St Privat exceeded anything hitherto seen on any battlefield, decided to call on the whole of his force to attack.
The French artillery had already evaded the coming blow, and had changed position, "right back," to cover the flank of the rest of the army, and the Prussian and Saxon artillery trotting forward conformed to this new front, their shells sweeping the ground for 2000 yds.
In round numbers one-third of their effectives had fallen - most of them in the first great rush forward at 5.30 p.m.; but actually they had been more or less under fire since about 2 p.m., and many were hit by French shells plunging into the turmoil about St Privat from 8 to 10 p.m.
But the remainder of the troops had to be withdrawn, and confusion breaking out in their rear, exposed to all the random bullets and shells of the French, a panic ensued, thousands of men breaking away and flying in wildest confusion through Gravelotte towards the west.
Two shells struck her between the mainmast and after funnel, and a vast column of smoke and fire rose into the air.
I buy my pecans from someone who picks and shells them himself.
It was hard, smooth sand, very different from the loose, sharp sand, mingled with kelp and shells, at Brewster.
The tang of the untainted, fresh and free sea air was like a cool, quieting thought, and the shells and pebbles and the seaweed with tiny living creatures attached to it never lost their fascination for me.
We also went nutting, and I helped them open the chestnut burrs and break the shells of hickory-nuts and walnuts--the big, sweet walnuts!
We gladly allowed her to use freely our library of embossed books, our collection of stuffed animals, sea-shells, models of flowers and plants, and the rest of our apparatus for instructing the blind through the sense of touch.
Finally she got up from the table and went through the motion of picking seaweed and shells, and splashing in the water, holding up her skirts higher than was proper under the circumstances.
And when he came to the nut trees, and saw the shells left by the idle fairies and all the traces of their frolic, he knew exactly how they had acted, and that they had disobeyed him by playing and loitering on their way through the woods.
I had the previous winter made a small quantity of lime by burning the shells of the Unio fluviatilis, which our river affords, for the sake of the experiment; so that I knew where my materials came from.
We talked of rude and simple times, when men sat about large fires in cold, bracing weather, with clear heads; and when other dessert failed, we tried our teeth on many a nut which wise squirrels have long since abandoned, for those which have the thickest shells are commonly empty.
All he knew was that at the commencement of the action balls and shells began flying all over his regiment and hitting men and that afterwards someone had shouted "Cavalry!" and our men had begun firing.
From different sides came whistling sounds and the thud of cannon balls and bursting shells falling on the town.
At first the noise of the falling bombs and shells only aroused curiosity.
In the disposition it is said first that the batteries placed on the spot chosen by Napoleon, with the guns of Pernetti and Fouche; which were to come in line with them, 102 guns in all, were to open fire and shower shells on the Russian fleches and redoubts.
From in front and especially from the right, in the unlifting smoke the guns boomed, and out of the mysterious domain of smoke that overlay the whole space in front, quick hissing cannon balls and slow whistling shells flew unceasingly.
At times, as if to allow them a respite, a quarter of an hour passed during which the cannon balls and shells all flew overhead, but sometimes several men were torn from the regiment in a minute and the slain were continually being dragged away and the wounded carried off.
The smaller dinner menu offers more traditional choices, from stuffed shells to crab cakes.
The crab shells turn from a dark burgundy to a bright red when cooked.
- A great part of the bottom of the Mediterranean is covered with blue muds, frequently with a yellow upper layer containing a considerable proportion of carbonate of lime, chiefly shells of pelagic Foraminifera.
All are built in the Doric style, of the local porous stone, which is of a warm red brown colour, full of fossil shells and easily corroded when exposed to the air.
A large variety of materials have been used in their manufacture by different peoples at different times - painted linen and shavings of stained horn by the Egyptians, gold and silver by the Romans, rice-paper by the Chinese, silkworm cocoons in Italy, the plumage of highly coloured birds in South America, wax, small tinted shells, &c. At the beginning of the 8th century the French, who originally learnt the art from the Italians, made great advances in the accuracy of their reproductions, and towards the end of that century the Paris manufacturers enjoyed a world-wide reputation.
In the shallower tropical waters, especially on the central ridge, considerable areas are covered by Pteropod ooze, a deposit consisting largely of the shells of pelagic molluscs.
The same law prevailing in all natures creation, in the plumage of birds, the painting of butterifies wings, the marking of shells, and in all the infinite variety and beauty of the floral kingdom, the lesson is constantly renewed to the observant eye.
Shells are obtained in great numbers and variety.
These enclosing surfaces, therefore, cut up the space into shells of potential, and divide up the tubes of force into electric cells.
