Mr. Burr ell to Mr. Ray. 



SIR, 9 Jan. 1694. 



I Have, Sir, in fome of my melancholick Hours* 

 been diverted by the Tra£fc I have of yours, and 

 particularly your Synopfts Animalium, &c. wherein I 

 obferve 'your Opinion fettled againft JEquivocal Gene- 

 rations^ and fol. if. confirmed by many Arguments, 

 and great Authorities : Yet if I had leave 1 would ask 

 if the Species of Worms bred in humane Bodies, or 

 thofe of Brutes, are at any time obferv'd to be gene- 

 rated elfe where ? For I fhould think it would be hard 

 to fay their Eggs are convey'd out of one Man, or

 that perhaps once in an hundred Years, will be more

 tur quo dv is animal a naturd it a faffum effe, ut cibi de- 

 glutitj partem aliquem vomitu femper aut etiam frequen- 

 ter rejicere debeat. I fhould here enquire whether the 

 Cafiings of Hawks, which you know conftantly throw 

 up lumps of Flix, or Feathers, or Down, £?V. (the 

 wild as well as the reclaimed) bring any of the Food 

 up with 'em, In fol. 309. I prefume there is an Error 

 in the Print, i. e. Hir undines for Hirudines. * You fee. 

 Sir, how confidently, not to fay impudently, I trou-
