... the shape of the lens. When the muscle contracts it allows the lens to bulge forward by virtue of its elasticity, and, therefore, become more convex. This is what happens when one looks at near objects, the increased convexity of the lens bending the rays of light so that they will focus as a point on the retina. (See Plate ...

... good hyacinth are clear bright colors, free from clouding or sporting, broad bold petals, full, large and perfectly doubled, sufficiently revolute to give the whole mass a degree of convexity: the stem strong and erect and the foot stalks horizontal at the base, gradually taking an angle upwards as they approach the crown, so as to place the flowers in a pyramidical form, occupying about one-half the length ...

... by little the arch grew higher against the dark void, like the form of the Spirit-maiden in the shades of Glenfinlas, till its crown drew near the zenith, and threw a tissue over the whole waggon and horses of the great northern constellation. Brilliant shafts radiated from the convexity of the arch, coming and going silently. The temperature fell, and Lady Constantine drew her wrap ...

... made of two parts, a broad piece of bamboo with a longitudinal slit at one end and a thin narrow piece of the same material, the reed, which was held firmly against the fenestra on the concave side of part number one. The convexity of the instrument was pressed against the lips and the sound was produced by projecting the breath through the slit in a speaking or singing tone in such a way as to cause vibrations in the reed. The manner of constructing and operating this reed instrument ...

... broad, flat face like unto the moon at full, or a dish. Her back was a little humped, her arms disproportionately long, losing in plumpness what they gained in extension. She seemed to have no breasts at all, the chest forming a concavity in correspondence to the convexity of the back, with a smoothness much like the inner surface of a bowl. This perhaps was no disadvantage—under the conditions. So much for fate. But fortune had been no kinder. "Blooming" into girlhood, she had been attacked by smallpox. Matazaemon was busy, and knew nothing ...

... little convex, to which the concavity of the upper must be fitted. In the middle of the upper stone is a round hole, and on one side is a long handle. The grinder sheds the corn gradually into the hole with one hand, and works the handle round with the other. The corn slides down the convexity of the lower stone, and by the motion of the upper, is ground in its passage." Such a primitive piece of machinery, it may safely be said, has entirely disappeared from this country.—In other parts of this work, we shall have opportunities of speaking of bread and ...

There is a cover to this pan whose convexity almost fits the concavity of the pan, leaving a space of about an inch between. Crushed ore with water is admitted at the center between the cover and the pan, and is driven by centrifugal force through a mass of mercury (which occupies part of this space between the two) and ...

... placing in front of the eye (Fig. 117b) a concave lens, to disperse the rays somewhat before they enter the eye, so that they come to a focus on the retina. If a person's sight is thus corrected for distant objects, he can still see near objects quite plainly, as the lens will accommodate its convexity for them. The scientific term for short-sight is myopia. Long-sight, or hypermetropia, signifies that the eyeball is too short or the lens too flat. Fig. 118a represents the normal condition of a long-sighted eye. When looking at a distant object ...

... and as it also has topographical relations with the mouth, it has been designated in English by the non-committal term stomochord. It is not a simple diverticulum of the collar-gut, but a complex structure possessing paired lateral pouches and a ventral convexity (ventral caecum) which rests in a concavity at the front end of the body of the nuchal skeleton (fig. 3). In some species (Spengelidae) there is a long capillary vermiform extension of the stomochord in front. The nuchal skeleton is a non-cellular laminated thickening ...

Observe, also, that it is constantly found, that so far from there being a concavity in the interior surface of the cranium answering to the convexity apparent on the exterior—the interior is convex too. Dr. Baillie thought there was something in the system, because the notion of the brain being an extendible net helped to explain those cases where the intellect remained after the solid substance ...

Both in shape and dimensions it was the grossest possible caricature of a Roman-nosed equine head the ...

... There is no difficulty in distinguishing this species from any of the Indian varieties. The immensely large ears constitute a marked characteristic of the former, which at once becomes recognisable. Other points of difference are the greater convexity of the forehead or skull and the larger size of the tusks; though this last point of distinction is not always to be depended upon, since there are Indian elephants with tusks of similar dimensions. Generally, however, the African elephants have ...

What is done in backing is to make a groove, into which the edges of the board will fit neatly, and to hammer the backs of the sections over one another from the centre outwards on both sides to form the "groove," to ensure that ...

On the contrary, the orbits are cleanly made and the suture is well curved. Besides, a low degree of intelligence ...

The other end is heated in the furnace and gradually beaten out until the peculiar shape of the blade is achieved, with the characteristic hollow on the one side and convexity on the other. If the blade is to be a simple and unadorned weapon, there follow only the tempering, grinding, and polishing. But many blades are ornamented with curled ridges projecting from the back edge. These are cut and turned up with an iron chisel while ...

This I will say for it—that, considering its size and weight, it is easily carried; for not only is there the crosspiece as hand-guard, but above this is a crescent worked in the iron, the horns extending with the convexity towards the point of the blade. By putting a couple of fingers under these horns, the sword is carried at the side, pommel downwards, blade up, with perfect ease, the balance is so true. Some difficulty ...

It would be out of place to state more than the principal result of the recent investigations by Dr. A. Schmidt[85] and Prof. P. Rudzki[86] on this subject. These are based on the assumptions that the velocity increases with the depth below the surface, ...

... already remarked that this species has some affinity to L. pectinata; but it is much more closely related to L. fascicularis, the affinity being clearly shown by the thinness and translucency of the valves, their convexity, by the width and little acumination of the upper part of the carina, by the width of the fork, and by its not being deeply imbedded. In young specimens, moreover, before the fork is fully developed, there is a remarkable similarity between the two species, in the form of this lower part of the ...

The columns were almost imperceptibly inclined ...

... light and beautiful to the eye, but the plan on which they are usually constructed does not imply much strength. Each stone, from five to ten feet in length, is cut so as to form a segment of the arch, and as, in such cases, there is no key-stone, ribs of wood fitted to the convexity of the arch are bolted through the stones by iron bars, fixed fast into the solid parts of the bridge. Sometimes, however, they are without wood, and the curved stones are morticed into long transverse blocks of ...

The upper side of one leaf, instead of being, as at first, slightly concave, now presented a strong convexity upwards. Even on the fifth day the leaves did not appear dead.

For this daring assertion he made way by the intermediate paragraphs, in which he observes, that the convexity of a semi-ellipsis may be increased at will to any degree that strength may require; which is, that an elliptical arch may be made less elliptical, to be made less weak; or that an arch, which, by its elliptical form, is ...
