... that we live here in the same solitude as we should do if cast on a rock in the middle of the ocean, and all the Londoners tell us there is between them and us a great, impassable gulf of mud. There are two roads through the Park, but the new one is so convex and the old one so concave, that by this extreme of faults they agree in the common one of being, like ...

... Noatak. As we travelled, these distant peaks began to take the most fantastic shapes. They flattened into a level table-land, and then they shot up into pinnacles and spires. Then they shrank together in the middle and spread out on top till they looked like great domed mushrooms. Then the broad convex tops separated themselves entirely from their stalk-like bases and hung detached in the sky with daylight underneath. And then these mushroom tops stretched out laterally and threw up peaks of their own until there were distinct duplicate ranges, one on the earth and one ...

... slightly crestfallen air. "And I thought I was acting the part of a person who was not mad about her to the life. Well, I never was any good at dissembling. I shouldn't wonder if even old Peppmueller noticed something through his double convex lenses. But however crazy I may have been as an undeclared suitor, I am going to be much worse now. Here's the place," he broke off, as the cab rushed down a side-street and swung round a corner into a broad and populous thoroughfare. ...

... closely together as might be expected, but should touch only at the center of the area to be joined (Figure 51). That is to say, the surface of the beveled portion should bulge in the middle or should be convex in shape so that the edges are separated by a little distance when the pieces are laid together with the bevels toward each other. This is done so that the scale which is formed on the metal by the heat of the ...

... to be distinguished from the bitter Chamomile (matricaria chamomilla) which has weaker properties, and grows erect, with several flowers at a level on the same stalk. The true Chamomile grows prostrate, and produces but [85] one flower (with a convex, not conical, yellow disk) from each stem, whilst its leaves are divided into hair-like segments. The flowers exhale a powerful aromatic smell, and present a peculiar bitter to the taste. When distilled with water they yield a small quantity of most useful essential oil, which, if fresh ...

This attractive person was always accompanied by a formidable dog—of convex limbs, shrunken lip, and suspicious demeanour—which he called Influenza, to the excessive amusement of those to whom he related its characteristics. For some inexplicable reason from the first it regarded my lower ...

... light horizontal balance was constructed by Mr. Michel, with about an inch square of thin leaf-copper suspended at each end of it, as described in Dr. Priestley's History of Light and Colours. The focus of a very large convex mirror was thrown by Dr. Powel, in his lectures on experimental philosophy, in my presence, on one wing of this delicate balance, and it receded from the light; thrown on the other wing, it approached towards the light, and this repeatedly; so that no sensible ...

The mouth, then unshaded by a mustache, had a slight upward turn at the corners, indicative of vitality and good-humor; the chin rounded out sharply convex from the lip. The round, strong column of the neck well supported the head; my mother compared it with that of the Apollo Belvedere, a bust of which stood in the corner of our sitting-room. The head was deep—a great distance between the base of the ear and the wing of the ...

The skull is nearly oval in form, convex externally, the bone being much thicker at the base than elsewhere, and it is, in every respect admirably adapted to resist any injury to which it may be exposed, thus affording ample protection to the brain substance which it envelops.

... "is perfectly simple. The ferrule of a knobbed stick wears evenly all round; that of a crooked stick wears on one side—the side opposite the crook. The impressions showed that the ferrule of this one was evenly convex; therefore it had no crook. The other matter is more complicated. To begin with, an artificial foot makes a very characteristic impression, owing to its purely passive elasticity, as I will show you to-morrow. But an artificial leg fitted ...

His eye was sharpened to see the point of a needle, but a tree only as a blotted mass! A man's mind was meant to receive as a mirror, not to concentrate rays like a convex lens! Was it not then likely that the first reading gave the true impression of the ethereal, the vital, the flowing, the iridescent?

I was perhaps the one who saw most of the Davidsons at home. What I noticed under the superficial aspect of vapid sweetness was her convex, obstinate forehead, and her small, red, pretty, ungenerous mouth. But then I am an observer with strong prejudices. Most of us were fetched by her white, swan-like neck, by that drooping, innocent profile. ...

Layard, in his first description of his startling "find," says: "They (the tablets) were of different sizes; the largest were flat, and measured nine inches by six and a half; the smaller were slightly convex, and some were not more than an inch long, with but one or two lines of writing. The cuneiform characters on most of them were singularly sharp and well-defined, but so minute in some instances as to be illegible without a magnifying glass." Most ...

Although the checkered figure is common on bowls, the Zuni artists have appreciated the fact that it would be out of place on the convex surface of the water vase.

The conical form is best expressed in the Melanian races, especially the Australian. The canine is more ...

When persons who ought to begin the use of convex glasses habitually strain the waning power of accommodation, an undue secretion of tears very often follows, and the retina is liable to become unduly sensitive to light. In general, morbid affections ...

... streams. Stout, ten-foot brush is the chief material. The brush is floated down to the spot selected; the tops are weighted down with stones, and the butts left free, pointing down stream. Such dams must be built out from the sides, of course. They are generally arched, the convex side being up stream so as to make a stronger structure. When the arch closes in the middle, the lower side of the dam is banked heavily with earth and stones. That is shrewd policy on the beaver's part; for once the arch is closed by brush, the current can no longer sweep away ...

The same facts were brought out at the bend of the river. On its convex side, Fig. 55, the water has rather further to go in getting round the bend than on its concave side B, it therefore flows more quickly, and carries away the soil of the bank and mud from the bottom.

There is also enlargement of the lower ends of the bones of the forearm and leg, and effusion into the wrist and ankle-joints. Skiagrams of the hands and feet ...

This was so nearly upright that its revolution could not be easily observed; but it certainly moved, and the side of the internode which was at one time convex became concave, which, as we shall hereafter see, is a sure sign of the revolving movement. I will assume that it made at least one revolution during the first twenty-four hours. Early the next morning its position was marked, and it made a second revolution in 9 hrs.; during ...
