Buxton bath is very frequently employed as a tem- 

 perate cold bath. For as the heat of the water is 

 about fixteen or eighteen degrees below that of the 

 human body, a gentle fhock is produced on the firft 

 immerfion, the heart and arteries are made to con- 

 tract more powerfully, and the whole fyftem is 

 braced and invigorated. But this falutary operation 

 mufl be greatly diminifhed, often indeed more than 

 counter -balanced, by the relaxing vapours which 

 copioully exhale from the bath, to which the pa- 

 tients are expofed during the time of dreffing and un- 

 dreffing. A feparate room is indeed provided for 

 the ladies - } but the gentlemen have no other accom- 

 modations than what the vault affords in which the 

 bath is contained, and are therefore liable to all the 

 inconveniences arifing from warmth and moifture. 

 June 12, 1772, the mercury itood in the (hade
