The country to the south not being very promising, we turned to the westward, recrossing the plain more to the south, passing several hollows, in which the rainwater had very recently rested, leaving a rich alluvial deposit from which had sprung up a splendid sward of grass, which was still quite green.

"The nature and origin of this vast deposit of clay is a question of the very greatest interest; and although I think there can be no doubt that it is in the main solved, yet some matters of detail are still involved in difficulty.

If blowing off be sufficiently practised, the scale upon the flues will never be much thicker than a sheet of writing paper, and no excuse should be accepted from engineers for permitting a boiler to be damaged by the accumulation of calcareous deposit.

It is one of the most valuable and extensive iron deposits in the world, and resembles those of Lake Superior.

Back in the very earliest Tertiary deposits, and in all certainty even earlier, a group of comparatively small mammals was extensively spread through America, and apparently less widely in Europe, characterized by a primitive form of foot structure, each of which had five complete digits, the whole sole being placed upon the ground, as in the animals we call plantigrade.

In this distress, my lords, they can only do what indeed they now seem to design; they can only repeal this act by charging the debt, which it has enabled them to contract, upon the sinking fund, upon that sacred deposit which was for a time supposed unalienable, and from which arose all the hopes that were sometimes formed by the nation, of being delivered from that load of imposts, which it cannot much longer support.

But it is not the only extensive deposit which is now taking place.

Sometimes it is found to contain a most precious deposit, the egg which is to produce a future fish.

When the annual floods have subsided, leaving behind a thick deposit of mud, wrack, and brushwood, the long thick grass soon shoots up to an amazing height, and vast herds of cattle and tame buffaloes come down to the jungles from the interior of the country, where natural pasture is scarce.

The phonolite stones of the Rhine, and the Tripoli stone, contain species identical with what are now contributing to form a sedimentary deposit (and perhaps, at some future period, a bed of rock) extending in one continuous stratum for 400 measured miles.

Like the Globigerina ooze, then, which it succeeds to the southward in a band apparently of no great width, the materials of this silicious deposit are derived entirely from the surface and intermediate depths.

[Footnote 9: The White River very probably flows over volcanic deposits as its sediments would indicate; no doubt this would account for the discoloration of its waters.

Even now, notwithstanding the obstructions caused by the immense deposits of ship-yard refuse at its mouth, a few of these fine fish are caught every season by one or two persevering anglers from Quebec,men who thrive on disappointment,whose fish-hooks are miniature anchors of Hope.

The female deposits from one to eight or more eggs upon a single plant of wheat, between the vagina or sheath of the inner leaf and the culm nearest the roots; in which situation, with its head towards the root or first joint, the young larva pass the winter.

Among the unanswerable, perhaps the weightiest of the objections, is that of the absence, in geological deposits, of vestiges of the intermediate forms which the theory requires to have existed.

The morbid changes consisted entirely of osseous deposit as shown in the photographs.

But the actual coal is but an insignificant portion of the total deposit, which, as has been seen, may amount to between two and three miles of vertical thickness.

In some of the islands the volcanic rock prevails, while in others coal and the metalliferous deposits predominate.

As far as is known, it is a recent development, for no very similar remains appear previous to post-tertiary deposits.

'My DEAR SIR, 'I ought to have thanked you sooner, for your very obliging letter, and for the singular confidence you are pleased to place in me, when you trust me with such a curious and valuable deposit as the papers you have sent me.

We have no emergencies that make banks necessary to aid the wants of the Treasury; we have no load of national debt to provide for, and we have on actual deposit a large surplus.

In the February number of this Journal the writer described a new settling tube for urinary deposits which possessed several advantages over the old method with conical test-glass and pipette.

We learned that the northern peninsula was composed of granite and recent volcanic rocks, together with secondary and tertiary deposits, while the southern peninsula is almost wholly volcanic.

For, suppose the globe to be evenly covered with sea, to a depth say of a thousand fathomsthen, whatever might be the mineral matter composing the sea-bottom, little or no deposit would be formed upon it, the abrading and denuding action of water, at such a depth, being exceedingly slight.

Hardy adventurers were tempted there, as in America, by privileges and inducements which power afforded them; as well as by the hope, which, fortunately for the country, was never realized, of its being rich in auriferous deposits.
