there. The maw being thus cleansed, the farrier sewed up the wound in it, 

 then thrust the maw back into the body ; and sewed up the wound in the rim 

 of the belly. The wound in the outward skin he did not sow up, but only 

 tacked it closely together about the middle, leaving room on both sides for 

 healing applications. The horse after this continued for some time much indis- 

 posed ; but in a month or six weeks, with careful attendance, the wounds were 

 closed and perfectly cured : and the horse worked as before ; and has ever since 

 continued sound and well. An account is then added of two cases in the 

 human subject, when a knife was swallowed down into the stomach : in the 

 one case, the side was opened, an incision made into the stomach, the knife 

 taken out, and the wounds sewed up again. In the other, after 20 months, 

 the knife made its way through, a little below the pit of the stomach ; after 

 which, the patient did well. 



Account of La vana Speculatione disingannata dal Senso : Lettera Risponsiva 

 circa i Corpi Marini, che Petrificati si trovano in varii Luoghi Terrestri.

This author endeavours to prove, which is now no longer doubted, that the 

 shells, or stones in likeness of shells, which are found in many places on the 

 surface, and in hills and quarries of the earth, were once real coverings of 

 inclosed fishes, or have been formed in those shells, which were instead of 

 moulds to the liquid matter that got in after the fishes were consumed. Signior 

 Scilla has brought more arguments in proof of this than had before appeared. 

 His way of writing shows little art, and less learning, which he owns himself 

 a stranger to, being by profession a painter at Messina. It is considered useless 

 to reprint any more of the account of this book, except the following explana- 

 tion of the figures which are engraved in Plate II. of this volume, and some 

 observations on them by a Fellow of the Royal Society. 



Fig. ], the head of the pesce vacca, drawn from the life, with the teeth in 

 both jaws. It seems to be of the long cartilaginous kind, a-kin to the dog or 

 hound fishes. — Fig. 2, 3, 4, 5, 6, the teeth of the same out of their sockets. 

 These are found petrified in beds up and down the island of Malta, with those 

 of dog-fishes, sharks, pesce aquila, &c. 



Fig. 7, a jaw of a fish called dentex, with the round grinders : the like dentes 

 molares are observed and drawn by the author in the jaws of other fishes, as 

 the aurata and sargus, with several bufonitae lying by them. These convex 

 osseous tubercles are found commonly petrified in Malta, and are called there 

 serpents' eyes. They are of the same kind with our English bufbnites or toad-
