HAIBS, FEATHEKS, 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 occupied 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 

 "j 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 

 small can perceive that each is formed of two half- 

 ^p" encircling scales ; for one scale occasionally

 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
