“As I have had ample experience of this cerate, I may be allow’d, I hope, to judge of its singular properties and good effects in all cutaneous ulcerations and excoriations either from scalding, burning, or fretting of the said parts by means of salt, acrid, or sharp humours; upon which accounts, not straining a tittle beyond its deserved euology, I am bold to affirm it will do more in all these superficial hurts of the body than either Unguentum Tutiae, Diapompholyx, Nutritum, Desiccativum Rubrum, Rosatum, or all the epuletic medicines now in use; and for which cause I can, for the public benefit, sincerely recommend it to all the professors of the art; and do wish that the Apothecaries would keep it made up in their shops, to deliver, at a suitable price, to indigent or poor people, instead of their ridiculous Locatellus’s Balsam, and other improper medicines which they call for ignorantly to heal their skin-deep maladies. I know the medicine has been imitated by several, and I have seen somewhat like it in some gentlemen’s salvatories; but I know not more than two persons I ever communicated it to, as I was wont to prepare it for my own use. The medicine thus prepared is of a good consistence and a true cerate, serving both for pledget or plaister, neither sticking troublesomely, nor running off or about by the heat of the parts; but keeping its body and performing things incredible. Whoever thinks fit to take it into practice will never repent it, nor perhaps (when he has experienced it as I have done) think I have said too much in its Commendation. This is the medicine I have so often taken notice of, which, that I might contribute my mite to the Surgeon’s Treasure of Medicine, I here have publish’d, and leave it to take its fate.” The other preparations to which Dr. Turner refers as being at that time in public demand may be briefly noted. Tutty was another impure oxide of zinc generally containing some oxide of lead or copper. It was obtained from the flues of smelting furnaces where zinc ores were purified. Tutty was so called from an Arabic or Persian name given to zinc, or to a zinc and tin bronze imported from China and used as a gong metal by the Chinese. The tutty ointment was properly made up with viper’s fat. Pompholyx was one of the names given to oxide of zinc prepared by combustion. It was a Greek word meaning a bubble in melted metal, from pomphos, a blister. Unguentum Diapompholyx contained besides the flowers of zinc, white lead, the juice of nightshade berries, and frankincense. Unguentum Nutritum was an acetate of lead ointment. Unguentum Desiccativum Rubrum was compounded from litharge, bole armeniac, calamine, and camphor. Unguentum Rosatum was similar to cold cream. XXI NOTED NOSTRUMS
