Always place the outdoor bed with the head well under cover and foot toward the opening of shelter, or if without shelter, toward the fire. Make the bed by arranging the branches shingle-like in very thick overlapping rows, convex side up, directly on the ground with thick end of stems toward the foot.
See Botanic Garden, P. I. addit. I am aware that this may be explained another way, by supposing the elasticity of the spring to depend more on the compression of the particles on the concave side than on the extension of them on the convex side; and by supposing the elasticity of the elastic gum to depend more on the resistance to the lateral compression of its particles than to the longitudinal extension of them.
Clouds were overhead, white masses with blue sky behind them. A day of brilliant sunlight. But soon, with our forward cruising, it was night. The sunlight dropped beneath the sharply convex horizon; the sea and the land went purple. A night of brilliant stars; the Earth was a blazing blue-red point of light. The heavens visibly were revolving; in an hour or so it would be daylight again.
The convex field stood bare, except for a few overthrown scarecrows in naked yellow or dusty blue, and for a jagged strip of earthwork torn from the crest, over which the Black Dog thrust his round muzzle. In a truce of empty silence, the defenders slept by turns among the sand-bags. The day came, and dragged by without incident.
As it was joined in a straight line with the rest, on separating, it was formed like the convex face of a crescent. This formation reduced its depth in the center. The intention of the general was to commence the battle with the Iberians and Gauls, and have them supported by the Africans.
Lyon gives the inventory of John Salmon of Boston in the year 1750 as the earliest record which he has found of the use of the word hall instead of entry, as we now employ it. In the Boston News Letter, thirty one years earlier, on August 24th, 1719, I find this advertisement: "Fine Glass Lamps & Lanthorns well gilt and painted both Convex and Plain.
I will content myself also with a mere reference to the remarkable experiment that enables us, with the aid of a piece of glass, to compel the bees to start their combs at a right angle; when they most ingeniously contrive that the enlarged cells on the convex side shall coincide with the reduced cells on the concave side of the comb.
In the actual apparatus the sphere is an ordinary round-bottomed flask about 95 mm. in diameter, and the lens a simple double convex lens of about 90 mm. focal length. The sensitive paper employed is the ordinary ferro-prussiate now so much used by engineers for copying tracings.
Imagine a vertical section to be made through the middle of the column. If, then, the diminution of the shaft were uniform, the sides of this section would be straight lines. In reality, however, they are slightly curved lines, convex outward. This addition to the form of a truncated cone is the entasis. The channels or flutes in our typical column are twenty in number.
Ward, of a specimen mounted as in the act of display, it may be seen that on the feathers which are held perpendicularly, the white marks on the ocelli, representing light reflected from a convex surface, are at the upper or further end, that is, are directed upwards; and the bird whilst displaying himself on the ground would naturally be illuminated from above.
