The cylinder once lighted, the hydrogen in the spiral and in the concave
cone becomes heated, and rapidly ascends through the pipe that leads to the upper part of the balloon.
Some parts brilliantly lighted, especially on its concave
part, showed the presence of high mountains, often disappearing behind thick spots, which are never seen on the lunar disc.
In ordinary combs it has appeared to me that the bees do not always succeed in working at exactly the same rate from the opposite sides; for I have noticed half-completed rhombs at the base of a just-commenced cell, which were slightly concave

I cannot refrain from once again remarking on the singularity of these complex structures -- a great sandy and generally concave
disk rises abruptly from the unfathomable ocean, with its central expanse studded, and its edge symmetrically bordered with oval basins of coral-rock just lipping the surface of the sea, sometimes clothed with vegetation, and each containing a lake of clear water!
The fierce flame fluttered like a silk flag, throwing an angry swaying glare mingled with moving shadows over the poop, lighting up the concave

The flanks of the dark, moving mass, were advanced in such a manner as to make a concave
line of the front, and every fierce eye, that was glaring from the shaggy wilderness of hair in which the entire heads of the males were enveloped, was riveted with mad anxiety on the thicket.
Cutting Board, meanwhile, turns the traditional carving board inside out, with a design that features a concave
center to hold juices in place and Gripper technology to hold the board still.
It follows a fire in Linthwaite, when the concentration of the sun's rays by a magnifying concave
mirror set a box of Christmas decorations alight.
