five grains of magnefia, part of which is united with 

 marine, part with aerial acid ; and nearly five grains 

 of iron combined with aerial acid. It alfo yielded 

 thirty-two ounce meafuresof air, twenty-four of which 

 were fixed air, the reft azotic with a portion of hepa- 

 tic air. The dofe is from one pint to three or four. 

 It operates with great eafe, and is never attended with 

 gripings, tenefmus, &c. It is belt taken a little warm. 

 It alfo creates an appetite -, is thought excellent in fcor-

 thirty-five pints of water an hour, without frugal ma-

HARROWGATE. < There are four fprings at this 

 place, but the waters of all of them are nearly alike, 

 except in the quantity of the faline matter they con-
