This is the main purpose of the machine we now illustrate in section, in which the pressing is done continuously by what may be termed a species of ironing. The machine consists of a central hollow cylinder, C, three-quarters of the circumference of which is covered by the hollow boxes, M, heated by steam through the pipes shown, and which are mounted upon the levers, BB', whose fulcra are at bb.
Other men then fill up the space beneath it with earth and stones. The process is next repeated with higher fulcra, until the stone is level with the top of the clay slope, on to which it is then slipped. With a little help it now slides down the inclined plane to the bottom. Here a fresh slope is built, and the whole procedure is gone through again.
Four main classes of mind were distinguished, called, respectively, the Poietic, the Kinetic, the Dull, and the Base. The former two are supposed to constitute the living tissue of the State; the latter are the fulcra and resistances, the bone and cover of its body.
Inflammation of the proximal sesamoid bones is caused by any kind of irritation which may involve this part of the inhibitory apparatus. Positioned as they are, between the bifurcations of the suspensory ligament and the pastern joint, they serve as fulcra and effectively assist in minimizing concussion which is received by the suspensory ligament.
Osbeck, a pupil of Linnæus, mentions the American frog fish, Lophius Histrio, which inhabits the large floating islands of sea-weed about the Cape of Good Hope, and has fulcra resembling leaves, that the fishes of prey may mistake it for the sea-weed, which it inhabits. Voyage to China, p. 113.
The other method of moving the stones is as follows: a gentle slope of hard earth covered with wet clay is built with its higher extremity close beside the block to be moved. As many men as there is room for stand on each side of the block, and with levers resting on beams or stones as fulcra, raise the stone vertically as far as possible.
'The cube, product of the plane multiplied by itself, corresponds with locomotion in the air, where the aëronaut, being surrounded on every side by fulcra furnished by the various strata of the atmosphere, moves at will in every direction; pressing on the higher strata in ascending, on the lower in descending, on the lateral in turning to the right or to the left, and thus commanding a sphere of locomotion whose extent and facilities, compared with those afforded by the water, are as the cube to the plane.
Had not the luck of the British army led them to the village, it can hardly be doubted, and certainly was not doubted by any who were there, that the guns would have been captured and the general killed. Fortune, especially in war, uses tiny fulcra for her powerful lever.
Where the position of the animal is such as to throw the weight of the viscera into the pelvis, the brim necessarily widens, these weighty organs sink lower, and the beads of the thigh-bones acting as fulcra permit the crest of the ilium to be carried outward, while the lower part of the pelvis is at the same time contracted.
Quoins were blocks of wood, square, and wedge-shaped, with ring-hooks screwed in them for the greater ease of handling. Two of the gun's crew raised the base of the cannon upon their handspikes, using the "steps" of the gun carriage as their fulcra. A third slid a quoin along the "bed" of the carriage, under the gun, to support it at the required height.
