Where there is a difficulty of fwallowing in apoplectic or par- 

 alytic patients, or in thofe near death in fevers, or other difeaf- 

 es, no fluid fhould be put into their mouths as they lie upon 

 their backs, left it mould choke them ; but they mould be raifed 

 and fupported upright in their beds, and ftimulated by ftrong 

 light, and fpoken to in a louder voice, defiring them to Iwallow, 

 as the fluid is put into the mouth, and the fpoon mould be im- 

 mediately withdrawn, that they may clofe their mouths. Hence 

 if they cannot fwallow, it will flow out of their mouths, and not 

 endanger fufFocating them. See Hemiplegia, Spec. 10, of this 

 genus. 



1 7. Mors a frigore. Death from cold. The unfortunate 

 travellers, who almoft every winter perifh in the fnow, are much 

 exhaufted by their efforts to proceed on their journey, as 

 well as benumbed by cold. And as much greater exercife 

 can be borne without fatigue in cold weather than in warm ; 

 becaufe the exceflive motions of the cutaneous veflels are thus 

 prevented, and the confequent wafte of fenforial power 5 it may 

 be inferred, that the fatigued traveller becomes paralytic from 

 violent exertion as well as by the application of cold. 



Great degrees of cold afFecT: the motions of thofe veflels moft, 

 which have been generally excited into *lion by irritation ; for 

 when the feet are much benumbed by cold, and painful, and at 

 the fame time almoft infenfible to the touch of external objects, 

 the voluntary mufcles retain their motions, and we continue to 

 walk on ; the fame happens to the fingers of children in throw- 

 ing fnow-balls, the voluntary motions of the mufcles continue, 

 though thofe of the cutaneous veflels are benumbed into inac- 

 tivity. 



Mr. Thompfon, an elderly gentleman of Shrewfbury, was 

 feized with hemiplegia in the cold bath ; which I fuppofe might 

 be owing to fome great energy of exertion, as much as to the 

 coldnefs of the water. As in the inftance given of Mr. Nairn, 

 who, by the exertion to fave his relation, perifhed himfelf. See 

 Seel. XXXIV. 1.7. 



Whence I conclude, that, though heat is a fluid ncceflary to 

 mufcular motion, both perhaps by its ftimulus, and by its keep- 

 ing the minute component parts of the ultimate fibrils of the
