As he thundered out this he made a rush at Bildad, but with a marvellous oblique, sliding celerity, Bildad for that time eluded him.
Respectively; E1E1 a bar sliding in a diametral groove in the face of Di; E2E, a bar sliding in a diametral groove in the face of Di: those bars are fixed together at A, so as to form a rigid cross.
This sliding movement is resisted by placing a check rail on the inner side of the inner rail, to take the lateral thrust of the wheels on that side.
Already has it been related how the great leviathan is afar off descried from the mast-head; how he is chased over the watery moors, and slaughtered in the valleys of the deep; how he is then towed alongside and beheaded; and how (on the principle which entitled the headsman of old to the garments in which the beheaded was killed) his great padded surtout becomes the property of his executioner; how, in due time, he is condemned to the pots, and, like Shadrach, Meshach, and Abednego, his spermaceti, oil, and bone pass unscathed through the fire;--but now it remains to conclude the last chapter of this part of the description by rehearsing--singing, if I may--the romantic proceeding of decanting off his oil into the casks and striking them down into the hold, where once again leviathan returns to his native profundities, sliding along beneath the surface as before; but, alas! never more to rise and blow.
Each instrument is accompanied by a pair of weights and by a square root table, so that the product of the square root of the number corresponding to the position of the sliding weight and the ascertained constant for each weight, gives at once the value of the current in amperes.
In the Testicardines, where no such sliding action of the valves was necessary or possible, no muscles for such an object were required, consequently none took rise from the lateral portions of the valves as in Lingula; but in an extinct group, the Trimerellidae, which seems to be somewhat intermediate in character between the Ecardines and Testicardines, have been found certain scars, which appear to have been produced by rudimentary lateral muscles, but it is doubtful (considering the shells are furnished with teeth, though but rudely developed) whether such muscles enabled the valves, as in Lingula, to move forward and backward upon each other.
And backward on each i, Transmedial or sliding muscles.
Cesses for the ends of the studs are formed so as to draw the beam without strain into its true position every time that it is thrown out of gear by the sliding frame.
The advantage of this plough over the ordinary form is in the absence of sliding friction, and in the mellow and porous condition in which it leaves the bottom of the furrow.
So that it is greater the farther the point of contact is from the line of centres; and at the instant when that point passes the line of centres, and coincides with the pitch-point, the velocity of sliding is null, and the action of the teeth is, for the instant, that of rolling contact.
