TO THE SECOND EDITION. 



FROM the very flattering reception of the Author's 

 Lectures on Natural History, he has been encouraged, 

 at this early period, to submit to perusal a second edition, 

 to which have been added two Lectures on the Mammi- 

 ferous Animals, as since delivered before the Philosophical 

 Society, of which he has the honour to be one of the Vice 

 Presidents. 



He has only to hope, that the publication of the two 

 additional Lectures, may not weaken the favourable impress- 

 ion which the former ones appear to have made ; and that 

 the whole will tend to promote the object which, as before 

 intimated, the Author has had chiefly in view ; namely, 

 the study and contemplation of nature, in all her various 

 attributes.
