It feems, if any regard was hadin its Contrivance to Example, tohave chiefly followed the Unguen-tum Aureum of Mefue, juft beforetaken notice of ; but that is a muchneater Compofition than this, thobpth pretty nearly agree in Inten-tion. Nicolaus hath indeed a Pre-fcription under the Title of Unguen-tum Bafilicon Citrinum, which theAuguflan Difpenfatory hath tranf-crib'd ; but that is a very injudici-ous Medley of Ingredients of diffe-rent Virtues, notwithstanding Zwel-fer takes a mighty deal of Pains inhis Animadverilons to direct themanner of compounding it. All theLondon Difpenfatoues before thelait have likewife retained fromMefue an Unguentum B.ifilicon Ma-ins, but it is a moft perplexed Mix-ture and never ufed, and thereforevery juftly omitted here.

This likewife was never beforein any officinal Difpenfatory, andhath the Credit of the fame Con-triver as the foregoing ; tho verymuch like unto this hath been longmade in the Shops a Succedaneumto the Unguentum F.mulatum cumMercurio, which feems to have ow-ed its Invention rather to Cheap-nefs and Difpatch, the infeparableMotive to a wholefale Medicine-maker, than any laudable Defignor Improvement. The AuguflanDifpenfatory indeed gives an Un-guentum Mercuriale, which is vaft-

ly differing from this, and croudedwith a ftrange Deformity of Ingre-dients ; but Zwelfer in his Animad-verfions thereupon, gives one muchmore fímple, and that differs notgreatly from this, but in the ad-dition of Oils from Guaiacum andStorax. In his Notes upon that,he fays, that the bed way of mixingMercury with unguents, is to dif-iblve in it Aqua Fortis ; and afterthat DifTolmion is well mixed withLard, to evaporate the Ac¡ua Fortisover a Fire, in a Glafs VefTel. ButI conjecture that the Mercury byfuch Management would alfo ex-hale, or run again into its naturalGlobules ; or, that a great deal ofit wou'd, however, be fo loft.
