This little work forms the Hrst of a New Series designed to assist young per- 

 sons to a more profitable, and, consequently, more pleasurable observation of 

 Nature, by furnishing them in a familiar manner with so much of the science as 

 they may acquire without encumbering them with more of the technicalities, so 

 confusing and repulsive to beginners, than are necessary for their purpose. In 

 lhe_ words of the Preface, it is " somewhat on the scheme of a Delectus; com- 

 bining extracts from the biographies of individual objects with principles of 

 classification and hints for obtaining further knowledge."
