teeth were found along with them, and even among those figured by Count 

 Marsili, there are three grinders, and a considerable part of one of the 

 dentes exerti. 



Dr. Plot, in his Natural History of Staffordshire, says, That he was pre- 

 sented by William Leveson Gower of Trentham, Esq. with the lower jaw of 

 some animal, with large teeth sticking in it, dug up in a marl pit in his 

 ground, and which, on comparison, he found exactly agreeable to the lower 

 jaw of the elephant's skull in Mr. Ashmole's Museum at Oxford, 



In the Museum of the Royal Society there are two fossil-bones of elephants: 

 one was given by Sir Thomas Brown of Norwich, the other was brought from 

 Syria for the os tibiae of a giant ; but Dr. Grew proves by an exact computation, 

 that it can never have been the os tibiae of a human skeleton, by being full 20 

 times as thick, and but 3 times as long. It is 42 inches long, and 12 in 

 circumference, where it is thinnest. Dr. Grew observes, that by the figure it 

 appears to have belonged to the leg, and not to the thigh, and he conjectures 

 the whole elephant to have been about 5 yards high. 



Gessner says, that he was presented by a Polish nobleman with a tooth, four 

 times as large as that which he figured under the title of Hippopotamus, in 

 his book de Aquatilibus. It was found under ground, in digging for the 

 foundation of a house, together with a very large horn, as they called it, which 

 many took to be a unicorn's horn, but erroneously, as Gessner thought, be- 

 cause of its being too thick and too crooked. It is very probable that this 

 pretended horn, was the dens exertus of an elephant. The same author men- 

 tions a subterraneous cavern near Elbingeroda, where were found the bones 

 and teeth of men and animals so large, that it was scarcely credible that ever 

 any of that bulky size should have existed. 



The grinder of an elephant, petrified, is kept in the king of Denmark's 

 cabinet at Copenhagen, as appears by the catalogue, but no mention is made 

 how it came thither, or where it was found. 



In the same collection they show a large thigh-bone, which weighs about 20 

 Danish pounds, and is above 3 feet in length. It is so old, according to the 

 author of the catalogue, that it is almost become stony. The same author 

 mentions another large bone, then in the collection of Otho Sperling, which 

 weighed 25 lb. and was 4 feet long, said to be found in the year l643 at 

 Bruges in Flanders, where was the whole skeleton, which was 20 yards of 

 Brabant in length. 



A piece of ivory was dug up in a field on the river Vistula, about 6 miles 

 from Warsaw, which having been shown at Dantzic to Gabriel Rzaczynski,
