5 04 MifcelUnea Curiofa. Vol. ttl. 



Gentlemen mofl: famed for fuch fort of To- 

 bacco, as of Pr/(?r-feed, &c. Nay, the iame 

 fort of Seed in different Earths, will pro- 

 duce Tobacco much different, as to good- 

 nefs. The richer the Ground, the better it 

 is for Aranoko Tobacco^ whofe Scent is not 

 much minded, their only aim being to have 

 it fpecious, large, and to procure it a bright 

 Kite's Foot colour. Had not my Microf-

 ling Galls, how with the Syrup of Violets, 

 and how they would have percipitated Mer- 

 cury, or the like, and fo far forth as I had 

 been able , examined them by the feveral 

 Tryals of Fire. I conceive Tobacco to be 

 a Plant abounding with Nitro-Sulphurious 

 Particles; for the Planters try the goodnefs 

 of their Seed, by cafting a little thereof in- 

 to the Fire i if it be good, it will fparkle 

 ^fter the manner of Guil-powder : fo will the 

 Stalks of Tobacco-leaves^ and perhaps has 

 ^bmething analagousto the Narcotick Sulphur 

 oiVenm^ which the Chymifts fo indultrioufly 

 labour after. The World knows little of 

 the efficacy of Its Oyl, which has wonderful 

 Eff^edls in the curing of old inyeterate Sores^ 

 and Scrbphuloiis Swellings, and folrie, other- 

 wife applied aad qualified. The goodnefs 

 of Tobacco I look on primarily confifts in 

 the Tolatiiity of its Nitre : And hence the
