Even this, however, is far excelled by a species of Bat from India, of whose hair I have now specimens on the stage. The trumpet-like cups are here very thin and transparent, but very expansive ; the diameter of the lip being, in some parts of the hair, fully thrice as great as that of the stem itself. The margin of each cup appears to be imdivided, but very irregularly notched and cut. In the middle portion of the hair, the cups are far more crowded than in the basal part, more brush- like, and less elegant; and this structure is continued to the very extremity, which is not drawn out to so at- tenuated a point as the hair of the Mouse, though it is of a needle-like sharpness. The trumpet-shaped scales are, it seems, liable to be removed by accident; for in these dozen hairs there are several, in which we see one or more cups rubbed off, and in one the stem is destitute of them for a consid- erable space. The stem so denuded closely resembles the basal part of a Mouse's hair in its normal condition. This character of being clothed with overlapping scales, each growing out of its predecessor, is common, then, to the hairs of the Mammalia, though it exists in different degrees of development. It may be readily detected by the unaided sense, even when the eye, though as- sisted by the microscope, fails to recognise it. Al- most every schoolboy is familiar with the mode.
