scales, Miiich arc excessively tliin, and lie close. The 

 pitli consists of largo flattened cells, arranged tlius : 

 one row passes np tbrongli the cen- 

 tre, and other similar ones are set in 

 a circle around it, so that a longitu- 

 dinal section would show three par- 

 allel roM's. These cells are translu- 

 cent, and some of them are either 

 wholly or partially lined with a clear 

 yellow pigment. 



The smaller hairs from the 

 same little animal are scarcely 

 distinguishable from those of 

 the Cat, already described, ex- 

 cept that the imbrications are proportionally 

 larger. In all, the extremity is drawn out to 

 a lengthened line point, and is occupied with 

 clear j^ellow 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 th.e 

 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 suc- 

 cessors to the very edges, or nearly ; but the 

 lower part, which is more slender, rcsen)bles
