HAIRS, FEATHERS. AND SCALES. 11 



are either wholly or partially lined with a clear yellow 

 pigment, or colouring- matter. 



The smaller hairs from the same little animal 

 are scarcely distinguishable from those of the Cat, 

 already described, except that the imbrications are 

 proportionally larger. In all, the extremity is 

 drawn out to a lengthened fine point, and is occu- 

 pied with clear yellow cells, except the very tip, 

 which is colourless, and imbricated with sinuous 

 whorls, each consisting of a single scale. 



But it is in the Bats that the imbricated 

 character attains its greatest development. 

 On this slide is a number of hairs from the 

 fur of one of our English Bats, in which it is 

 far more conspicuous than in any example 

 we have yet seen. In the middle portion of 

 each hair the scales lie close, embracing their 

 successors to the very edges, or nearly : but 

 the lower part, which is more slender, re- 

 sembles a multitude of trumpet-shaped flowers 

 formed into a chain, each being inserted into 

 the throat of another. The lip of the "flower'' 

 is generally oblique, and here and there we 

 can perceive that each is formed of two half- 

 encircling scales ; for one scale occasionally 

 mouse, springs from the level of its fellow, so as to " A bat. 

 make the imbrication alternate. 



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 undivided, 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
