there is not any Thing in either of them which 

 provokes the Horfe to fnort or fneeze; therefore wa 

 are to attribute the Good (if any) it does wholly to 

 the Feathers, which, by tickling and irritating the 

 Olfaftcry or Smelling Nerves fpread about in the 

 Nolirils^ caufes Sneezing : Yet in my Thoughts^ 

 tJiere are feveral Things may be thought of, under 

 the Tribe or Clafs of Sternutatories or Sneezing-Pow- 

 ders, that will anfwer the Epd better, and with, 

 much \t{i Uneafmefs than the Goofe-Quills. 



How a Medicine occafions the Convulilve Mo- 

 tion termed Sneezing or Snorting, in Brutes as well 

 as Human Creatures, is not at all difHcult to under- 

 hand : For the Fibres and Membranes within-fidg 

 ^he Noftrils are extremely fenfible : Whatfoever 

 therefore flimulates them, makes them contract, 

 and thereby pull thofe Parts they have any Commu- 

 nication with, which h/ Degrees brings on that 

 general Convulfive Shake, that throws off the irri- 

 tating Matter. 



Every one's own Experience demcnftrates, and 

 belt explains to himielf, how this is produced ', and 

 Jikewiie manifefls xho. great Inflviences which may 

 be communicated over the whole Body, by the Com- 

 munication of Fibres, from an almoft unheaded Sen- 

 .fation upon the leaft. Part. 



The Salutary Effcds of this forcible Concufiion of 

 the whole Body, are very confiderable. There are 

 many Glands or Kernels about the Head, deftined 

 for the Separation of very vifcid and mucous or 

 ilimy Subftances j by which Means many Sinus's or 

 Cavities, of feme Service in the Animal Oeconomyy 

 ^re frpqnently fo ftufFed with fudi Matter, as not to 

 give that P^oom to feme of the Veffels, as it is their 

 OiHce to do ', whereby the Circulating Fluid in 

 fome Parts makes them too turgid or full, which 

 ^pon many Accounts will occafion uneafy Senfations, 

 I?ain, Giddineff., and other Diflempers, frequently 

 experienced in the He^d.
