The increasing taste for the study of the 

 Natural Sciences, has created the necessity 

 of an elementary work on the most interest- 

 ing of them all, the science of the Animal 

 Economy, in which every thing of a strictly 

 professional nature, and whatever else would 

 be improper for general readers, should be 

 carefully excluded, and the whole rendered 

 intelligible to the minds of the young and 

 the unlearned. To meet this necessity has 

 been the object of the author in preparing 

 the following sheets. To the merit of origin- 

 ality, he lays no pretensions ; but if the man- 

 ner in which the subject is here treated, 

 shall prove an inducement to acquire some 

 useful and interesting knowledge concerning 

 the noblest of the works of nature, it is the 

 only merit that he would claim. How far he 

 has succeeded in accomplishing this object, is 

 for instructers and common readers to say. 



Portland, May 11, 1829.
