Upon viewing - the V ulcanos about Naples, Fefuvlus 
* ©n the Eaft fide, the Solfatara and Monte di Cinere on the 
Weft near Puzzuolo and Baj£; I obferv’d the fame Face 
of Nature, which I believe runs thro’ all the other Vnl - 
cano's of our Globe, viz. heaps of Pumice Stones and 
Cinders of Marchafites on the Tides, with Beds of Flower 
of Brimftone on the tops. The Holes and Cavities in

Canes, Rice, Maiz, abundance of the purging Senna, and 
Cummin Seed. Thro’ the whole Campania of Naples I ob-

than in other parts of Italy, as the Plat anus, the Lentifcus, 
-the Tershinthus, the Pi (laches, the Oleanders, Agnus Cafius, 
Barba Jovis, the Tragacanth , the Styrax, the Capers , &c* 
The Melons, Jujubes, the Azaroles, and other Fruits
