glafs, fciments fliglitly with acids, turns iilvcr black, and feems 

 copioufly charged with volatile particles, combined with a phlo- 

 giilic, a calcareous earth, and a portion of fixible air : it has a nau- ' 

 leous tafte when drunk at the rock ; but this leaves it on beino^ 

 fome time kept. The face of the rock over which it flows is co- 

 vered with an ochrous precipitation, impregnated with fulphur. 

 It is remarkably beneficial in all capillary obfh-u6lions and diforders 

 of the breaft, proceeding from weaknefs, or want of the proper 

 glandular fecretions ; in all lentors and vifcidities, proceeding from in- 

 a£lion ; in confumptions, and nervous fpafms. It reftores the ap- 

 petite, and natural adion of the bowels ; invigorates the circula- 

 tion ; warms the juices ; opens the Ikin ; cleanfes the urinary pal- 

 fages; ftrengthens the nerves; and feldom fails to procure an eafy 

 deep at night. Externally ufed, by way of a fomentation, it has 

 been known to heal the moft obftinate ulcers. In paralytic com- 

 plaints it is generally fuccefsful, and has recruited many conftitutions 

 that were impaired by debauch, or lingering intermittents. Nu- 

 merous as its known virtues are, it ftill requires a more thorough 

 analyfis. Some other particulars likewife ought to be afcertained, 

 in order to make it of more general ufe. But, of the diiTerent 

 phyficians who have refided here, I know of none that has 

 been at the pains to examine it fcientifically, or atleaft that has fa- 

 voured the public with any difcovery of the principal purpofes to 

 which it is applicable in medicine, or of the methods by which it 

 may be beft adminiflered, to anfwerthe cure of difeafes ; or of the 

 fubftances proper to be ufed at the fame time with it. Thefe parti- 

 culars are left at prefent to the difcretion of the patients, who drink 

 it, for the moft part, with very little attention to rule or meafure; 

 and therefore fome of them do not reap all the advantages from the 

 ufe of it, which, under due regulation, it might be capable of pro- 

 ducing. The general enquiries are, 



1. What is the fitteft ftate in which the water fliould be drank? 



2. The quantity? 



3. Time of the day? 



4. Length of time proper for it to be continued r 



5. Seafon of the year in which it is moft efficacious?
