as are attended with local inflammation, as plcuri- 

 fies, peripncumonies, inflammations of the bowels, 

 &c. Sometimes the brain is primarily affected, 

 probably from the immediate effect of the fun's 

 rays upon the head. The eyes are alfo liable to be 

 inflamed from expofure to ftrong light. Moif- 

 ture, efpecially when combined with either of the 

 above extremes of temperature, is produ^ive of 

 feveral diforders. 



People who work in the open air, and oftentimes 

 at a diftance from fhelter, muft neceffarily be ex- 

 pofed to cafual fhowers at every feafon of the year. 

 If thefe happen in cold weather, they aggravate the 

 bad effects of cold, by conveying it to a clofer con- 

 tact with the (kin, and alfo by the generation of 

 cold by evaporation. If rain fall fuddenly at a 

 warm feafon of the year, its effects are, I apprehend, 

 lefs dangerous than in cold weather to thofe who 

 are wet with it; neverthelefs it is not void of ha- 

 zard, efpecially if the perfons expofed to it have 

 been previoufly much heated, either by the weather, 

 or exercife. 



The evaporation of the moifture generates a de- 

 gree of cold, which is greater as the evaporation is 

 quicker. This then is one reafon, why the danger 

 of wet clothes is greater, as the body is more heated.
