(Slightly enlarged.) the same dust to adhere to this transparent mediuln, by applying which to the microscope you may at once discern the marvellous nature of the raiment with which the little creature is bedecked. The dust is now seen to be composed of myriads of thin scales, mostly regular and symmetrical in their forms, though varying exceedingly among themselves in this respect. Some are heart-shaped, some shovel- shaped, some round, oval, elliptical, half round, half elliptical, long and narrow, sometimes irregular and unequal, and of various other undescribable outlines. Perhaps the most common forms are ovate, heart- shaped, and that of the pan of a fire-shovel. Each thin scale has a minute foot-stalk, which is not connected.
