The special attention which Mr. Rodd bestowed for so many years on this branch of 
Natural History in his own county has eminently qualified him for the task of preparing 
this work ; and it is believed that the publication of his personal observations on the 
subject, of which a record has been regularly kept from the year 1843 to the present time, 
cannot fail to possess interest and value in the eyes of Naturalists.
