noxious and offenfive to them, that tliey drew "back from it fiifler 

 tlian tliey had ad\anccd towards it, in order to make their efcape out 

 of the glafs. 



Some others of the miles having advanced fo far as to have got 

 fome hairs hreadth diflance be^^ond the Nutmeg, were prefently 

 arrefted in their courfe, and, lofing all motion, they expired. 



Moreover, I obferved numbers of the mites creeping along the 

 glafs, near tliat part of the Nutmeg which was covered with 

 the rind, and they would have efcapcd, if I had not intercepted 

 them by placing another piece in tlie way, fo that they could not 

 get out without palfing tiie broken part of the nut, and hence it 

 appeared to me, that the vapour of the nut exhaled much more 

 -feebly next tiie rind, than from the internal newly broken part. 

 Hereby, not only the efcape of thefe mites was prevented, but all 

 tliat were near the nut died tiiere, and in the Ipace of eight and 

 forty hours, out of fo great a number of mites very few were left 

 alive. 



To explain this experiment better, I caufed a drawing to be made of 

 the glafs tube I ufed on the occafioji, which is to be feen in Plate X, 

 fg. 1 , A B C D E F G H I . Heie, A I is the open end of the tube ; F, 

 the end \\'hich wasclofed, and in which the mites, when firft put into 

 the tube, lay in the greateft numbers. Between CD and FG, was 

 placed the firft quarter of the Nutmeg with the internal broken part 

 next the eye, where fome of the mites had crept on the other fide of 

 the glafs next the rind, and pafied by the nut, when as I mentioned 

 before, I placed the other piece of nut, with its broken fide the con- 

 trary way to the other, fo that the rind appears between A B and 

 H I next the eye, by which the mites were prevented from efcaping, 

 and all died within the glafs. 



In refledling on the circumftance of thefe mites being thus killed, 

 I.judged that it was not by the vapour of the Nutmeg being hurtful
