covering a hat, is no contemptible defence againft 



folar heat. The eyes fhould likewife be confi- 



dered, which expofure to ftrong light is fo apt to 

 injure. This ihould be guarded againft by the 

 brim of the hat being made of a fufficient breadth 

 to fhade the eyes, and the infide fhould alfo be 

 tinged of either a green or blue colour, but by no 

 means either black or a very light hue, 



I have before mentioned the bad erTecls of cold 

 applied in any way to the body when violently 

 heated. This fhould ferve as a fufficient caution 

 againft fuch imprudencies. It may be ufefuj to 

 add, that as it may be neceftary to drink frequently, 

 It prevents much of the bad effects of cold liquor, 

 to eat fomething folid immediately before any liquid 

 be taken. A few morfels may be fufficient, and the 

 efficacy of the precaution is well known. 



The mifchievous confequences of cold liquors, 

 drunk in fuch cafes, are much aggravated when 

 they are, as is too common, fwilled down in enor- 

 mous draughts. Would thirfty people but have a 

 little patience, and drink fmall quantities at a time, 

 with proper intervals, as of a few minutes, the un- 

 eafy fenfation would be more effectually removed, 

 and that without any danger to health.
