fince the fenfe of {melling fens tobe made by the {witt patlage of the 
Air ( impregnated with the feats and effluvia of feveral odorows 
Bodies) through the grifly meanders of the Nofe whofe furfaces are | ( 
cover'd, with a very fenfiblé- nerve , and moiftned by a tranfuda- 
‘tion from, the proceflus mamillares of the Brain, and Jome ad- 
- joyning glandulés, and by the moift team of the Lusigs) with a Liquor 
convenient for the, reception of thofe efluvia and by the adbefion and 
mixing of thofe fleams with that liquor and thereby affeciing the nerve, or 
perhaps by infinuating themfelves into the juices of the brain, after the 
fame manner, a3 I have in the following Obfervations intimated, the parts 
of Salt topa/s through the skins of Effs,. and Frogs. Since, 1 fay, (melling 
feems to.be madeby fome fuch way, “tt not improbable, but that [owe con- 
trivance, for making a great quantity of Air pa/3 quick through the Nofe, \ 
might as much promote the fenfe of fimelling, as the any wayes bindring that a 
paifaoe does dull and deftroy it... Several tryals I have made, both of ge 
Pindring and promoting this fenfe,and have fucceeded in fome according to 
expeEtation ; and indeed to me it fees capable of being improv ‘d, for the 
judging of the confiitutions of of many Bodies. Perhaps we may thereby 
allo judge (as other Creatures fern to do) what is wholforne,e what poy(on + 
anil in a word, bat are the fpecifick. properties of Bodies. 
There may be alfo fome other mechanical wayes found out , of fenfibly | 
percetving the effluvia of Bodies ;. feveral Inftances of which, were it here 
proper, I could give of Mineral feams and exbalations ; and it eems mut 
impofible; but that by fome fuch wayes improved, may be difeovered, tee! :
