DEMOSTHENES. 



THERE is no division of natural history which lias so 

 much engaged the curiosity and attention even of the most

 Nature. From the first consideration of the Silk- Worm

 employment to a very large part of the community in every 

 country of the globe, and which is capable of being mixed 

 with a thousand other substances to an extent which can 

 hardly be conceived.

 in the form and colour of the wings. The spots which are 

 inserted upon the under side of the wings, are extremely 

 rich, being black and fenced with a half-moon mark of 

 pure white; the outer wings are of a rich purple verging te
