LETTER XIV, 

 To ***** ****** 



Dear Sir, 



Having compleated. 



an account of all the flies within my 

 knowledge, that are worth your atten-. 

 tion, it now remains for me to direct 

 the bed method of making them. 

 Though an art fo fimple in itfelf, it

 fingle fly made by an expert artift, than

 carefully defcribe the different methods 



that ;
