What is the use of rowing a boat, if you do not choose to let go the painter ? To solve this enigma, let us search up our little Brachion once more ; he will not roam long before he settles soberly again. Yes, here I have him moored. Now, mark care- fully the vortices, or whirlpools, which are so vigorously circling around the animal's front, and you will perceive that the movement is not a strictly circular one, but that each whirlpool has an outlet close to the cilia ; for the accumulated and... condensed particles of pigment, after many rotations, pass off in an united stream between the two crowns, and go away horizontally in a line from the ven- tral side of the front. That is to say, each vortex pours off its accumulation at a point on the inner side of the ciliary circle, and the two streams, uniting, pass off from the lip of the shell, to be drawn in again, however, by-and- by, when the centrifugal force is exhausted. Now this stream passes immediately over the mouth, which is an opening in the flesh of the front, forming a deep cleft on the ventral side, the lips of which, as also the whole interior of the tube, of which it is the orifice, are richly covered with cilia.
