THE Examination of Medical waters being fo ufefal 
both for the improvement of Phyfiology , and xhc 
Relief of the Health of man > we cannot but take publick no- 
tice in thefe Trafts of the difcourfes of chat Subjedt^that come 
abroad by the Prefs J wifliing only, that the Examiners of 
fuch matters, as well as of all others ^ would confider them
