Previous to the publication of Mr Jenyns's ex- 

 cellent Manual of British Vertebrate Animals, the 

 student of this branch of Zoology had no connected 

 descriptions of our Bats to which he could refer. 

 The characters there given will be found generally 

 satisfactory ; and a more extended and equally cor- 

 rect account of these animals has since been pre- 

 sented to the public in Mr Bell's History of British 

 Quadrupeds, which is illustrated by very beautiful 

 engravings on wood. To both these works the 

 author of this essay has been much indebted for in- 

 formation respecting several species with which he 

 was not personally acquainted.
