As to Medicines which abforb Acids, they are The Yir- 

 all the Teftacea or Shelly Powders, fuch as Coral^ 'i-^-^s of 

 Pearl, Crabs-Eyes, Burnt Hartshorn, Oypr-Shelh.J,''^^^'^^'^ 

 in Powder, or the like. And if you ask for any of 

 the firft Sort, 'tis ten to one the Apothecaries will 

 only let you have of Che laft ; which really is no 

 great Cheat, iince it is every Whit as good as any 

 of them, though it may be afforded for a Penny an 

 Ounce in very fine Powder ; and it fhould be finely 

 powder'd, or like the reft of the Teftacea 'tis not of 

 near fo much Service. 



There is a very fine white Oyfter-Shell gather'd 

 upon the Sea-Shores, which the London Druggifts 

 vend to their young Cuiloraers in the Country for a 

 Groat or Sixpence a Pound : But if you throw a 

 Parcel of large or any Oyfter-S hells upon Walls or 

 Out-houfes, to blanch or whiten, with the Weather, 

 Sun, i^c. the Powder of them wiH be as good as 

 any ; but it muft be {o prepared by grinding upon a

 the Body. 



In all Kinds of Loofenefies or Scourings, the 

 Horfe's Drink fhould be fparing and moderate ; for 

 if he be allow'd to take too much Liquid, it will 

 rather encourage than abate the Flux ot Scouring ; 

 and in all his Water let him^ have Gum-Arahick dif- 

 folved in it, according to the Diredlions given in 

 the Gum-Arahick Water for the wet Gripes or 

 Colick, when there happens a Purging along with it. 



It is a nice Thing to judge rightly when to ftop 

 a Loofenefs and when to encourage it r Therefore, 

 in the firft Place, if the Horfe's Appetite be good, 

 and that he has pretty well of Flelh upon his Back, 

 do not immediately go about to ftop his Scouring ; 

 for it may be, and very often is, the Out-let by which Many
