deserve the appellation of an ermine, did the animal prove a male ; and among those 

 which had assumed the change in a less degree, the number of females is in such ex-

 by far the most susceptible of this change, and shall be happy to learn, through the 

 medium of this journal, whether the observation of other naturalists on this point has 

 led to concurrent testimony. — Edward Murch ; Maidenhead, May 30, 1851.
