Buxton bath is v A ry 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 firfl 
immerlion, the heart and arteries are made to con- 
trad: more powerfully, and the whole fyflem is 
braced and invigorated. But this falutary operation 
muft be greatly diminifhed, often indeed more than 
counter -balanced, by the relaxing vapours which 
copioufly 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 ariling from warmth and moifture.
