Further along the limbs, in the portions which the sheathing still conceals, the legs are certainly softer still, and in the state of exquisite plasticity I had almost said fluidity which allows them to pass through narrow passages almost as a liquid flows. The teeth of the saws are already there, but have nothing of their imminent rigidity.
2dly, That when the agate was formed, the cavity then contained every thing which now is found within it, and nothing more. 3dly, That the contained substances must have been in a fluid state, in order to their crystallizing. Lastly, That as this fluid state had not been the effect of solution in a menstruum, it must have been fluidity from heat and fusion.
Yet turbid from the launching of its freight, Lake Como tossed to and fro its navies of good cheer, the shadows of the king-peaks wildly flitting thereupon. But no frigid wine and fruit cooler, Lake Como; as at first it did seem; but a tropical dining table, its surface a slab of light blue St. Pons marble in a state of fluidity.
Since that period there seems to have been a gradual development of heat; and this augmentation we may expect to continue till the whole globe shall be in a state of fluidity, or shall consist, in those parts which are not melted, of volcanic and crystalline rocks.
Seeing that very long, slender dikes are found penetrating the rock, which could not have had a high temperature, it becomes difficult to understand how the lava could have maintained its fluidity; but on the supposition that it was impelled forward by a strong pressure, and that the energy thus transmitted through it was converted into heat, we discover a means whereby it could have been retained in the liquid condition, even when forced for long distances through very narrow channels.
Each of them accordingly broke in its turn into several masses, which were plainly endued with a movement of rotation, coinciding in direction with the common movement of revolution, and which in consequence of their fluidity assumed spheroidal forms.
The substance of the fostering larva must be sufficiently fluid to ooze through the unbroken skin under the action of the sucker. Well, the necessary fluidity is realized as the time of the metamorphosis draws near.
Such a poet finds the rigid ethical system of a rationalistic philosophy as uncharacteristic of the actual fluidity of the world as ever Cratylus did. Feeling, but not reason, may be swift enough in its transformations to mirror the world, such a poet believes, and he imitates the actual flux of things, not with a wagging of the thumb, like Cratylus, but with a flutter of the heart.
At the same time the young composer was well versed in old and ancient music; he knew all the old scales, eight in number, and used them in his compositions with compelling charm. The influence of the old Gregorian chant has given his music a certain fluidity, free rhythm, a refinement, richness and variety peculiarly its own.
Mr. Girard proposes, therefore, to employ the water to act, first, by its pressure, to lift the Journal to be lubricated; and secondly, by its fluidity, to form a liquid bed or cushion between the journal and its box, on which the journal may rest in its revolution, without touching the metal of the box at all. The construction will be understood by referring to the figure.
