Eorty yoars liav6 ©lapsod. sincG tli© pulDlicaitioii of a Cornisli 
Fauna,” a compendium of the Natural History of Cornwall, and 
a convenient companion to the Museum of the Institution under 
whose auspices it was produced. Lapse of time, and a large multi- 
plication of observers have added much to what was then known, 
and it is gratifying to find that the constant wish of J onathan 
Couch is now fulfilled in a much needed second edition of the 
first pai-t. With such a desire he coUeeted largely, and even 
went so far as to write the following preface, which was found 
among his papers, and forwarded to the editor by his son, Mr. 
T. Q. Couch, of Bodmin. It wiU be seen that Mr. Couch con- 
templated adding to the original design, an account of such 
extinct animals as have had comparatively late entombment in 
our diluvial soils, gravels, drift, or cavern accumulations, and 
this still remains a work to be done.
