AnotheV caution highly necefiary for fuch perfcns 

 is, to put on their clothes immediately on their 

 leaving off work, and to do this without any regard 

 to the warmth of the weather. Nothing can be 

 more hazardous than for a perfon who is heated 

 with labour, and in a ftronc: peripiration, to remain 

 expofed to the wind. The exhalation both from the 

 body and the wet linen, produces a fudden and con- 

 fiderable degree of cold, which is not merely tran- 

 fient, but continues as long as the moifture is fuf- 

 fered to exhale freely into the open air. 



I have before remarked the hazard of labouring 

 perfons fleeping on the ground during the intervals 

 of their work. This is improper at all times, but 

 particularly dangerous if the ground be any wife 

 moilt. Indeed 1 am of opinion that fleep had better 

 be avoided altogcdier at fuch times; as fuch (lum- 

 bers produce but little refrefhment, and expofe the 

 health to unneceflary rifque. The body would be 

 fufficiently reded by the ceffation of labour, and 

 early hours in the evening would afford a fufficient 

 portion of time to be fpent in fleep. 



Moifture is equally necefiary to be confidered in 

 this place, with refpe£t to its effects on the health, 

 as heat and cold. This, I have before obferved, 

 cannot be always avoided, but the bad effects it 



fo me times
