cytopafs into fuch nerves rather than into others, 
In tht ficorjpin he treats of the Organs and Operations of the Ex* 
f^r^4S€iares in particular j where he defcends to various and very cu- 
rious Obfervations and Experimenrs, which do confiderably elucidate 
that fubjift. Difcourfing of the fenfe of Topich, he takes notice of the 
curious texture of the Skin, being found for the nioft part nothing but 
a woof of capillary nerves, arteries and veins,and receiving into it the 
ends of the excretory vcfl'els arifing from an infinit number of little 
glanduls, through which vefTeh the fweat and fleams do iffue.. Here 
aifo upon occafion he ingenioufly affigns the caufe of the Blacknefs of 
Negros', asalfoof that 111 arpriefs of A^^eat, that fometimes corrodes 
and makcth friable mens fliirts • of Rheumatifmes . of Gouts- of the 
Latitude and heavinefs in thick and rainy weather, &c fuggeftinp 
withall, feveral Remedies in fuch and other cafes* When he treats of 
the T4, he well confiders the ftrufture of the Tongue, and the nature 
of the Spittle, and the great number of the nervous papilU or Pttle 
teats in it ; and efteems, that the caufe,which fd quickly reviveth faint 
and fometimes dying perfons, is, that fome of the fubtUe and moft 
penetrating parts of iiquoVs adminiftred do enter into the faid nervous 
fafilU, and from thence pafs, in a moment, into the nerves themfelves 
of the body, and fo give new motion and refrefliraent.

When he giveth an account of the knttoi Smelling, betakes notice 
with Dr Jf^fe, of the great affinity there is between that lenfe and the 
Sight and Taftc, ana of the ground thereof; 'as aifo of the reafon whl
