    slightly injured or irritated, a much greater number of colourless cells are seen separating from the red stream, and becoming stationary upon the coats of the vessels. A line of lymph is at the same time visible between the blood current and the coats of the vessels, and in this the stationary cells seem to be embedded. It has been said this appearance has no re- ference to inflammation. We think, it is the first phenomenon of new cell-growth in the vascular tissue, the first act of a much more speedy change in the coats of the vessels than occurs in natural adult growth. The appearances certainly show a disposition in the blood, circulating in the living vessels, to separate into two parts, which are the same with those observed in many cases of inflam- mation after vencesection—that is, where a buflfy coat forms. And if, from other facts, it can be proved that the coats of the blood-vessels yield, and are replaced by new cell-growth, then the observation referred to, shows how the blastema of such growth may accumulate,—the colourless elements of blood being the first to occupy the breach. And from these elements, composed, as we know they are, of lymph, and cells, may proceed, we argue, the further appearances and properties of cell-growth.
