brifk Springs have this Character common 
to them with mineral Waters, that they 
weigh lighter at the Spring than afterward, 
and this fuch Baths lofe, by being carried 
off* from their Origin ; the fame Difadvan- 
tage attends in many Peoples bathing before 
the Bath is let off, and a new one gathered, 
where the Spring is not ftrong. Thus at 
Night, after People bathing all Day, the 
Spirits in the Thermometer flood at 30 ~ in 
Harrigate Bath, but next Morning, in a 
full Bath, they fell to 27. The Advantage 
of a Cold Bath beyond River, Brook, or 
Rivulet Water, is, that the firft keeps pretty 
near the fame Temperature in all Seafons 
of the Year, Changes of the Weather, and 
States of the Air, as to Heat or Cold, pro- 
vided it be a perennial Spring, and riles 
deep (and none other is fit for a Cold Bath.) 
But the Temperature of the lafl varies with 
Seafons, Air, and Weather ; the firft aifo 
retains the above Mark of a mineral Spirit, 
but the lafl do not. In Winter and Froffc 
thefe three are dangeroufly cold, and in Sum-

pofe, except to delicate People and Children, 
who, to reap any great Profit in chronic 
Diforders, muft ply them longer than ei-
