S08 On the Fossil Bones of Wellington Valley. 



Phascolomys, or Wombat, one species. 

 Elephant, one species. 



94, That of these nine animals only two species of kangaroo 

 do not differ in their anatomical characters from species inhabit- 

 ing the same continent ; whereas there is reason to suppose that 

 the seven remaining species differ from all those hitherto known 

 to zoologists^ and that some of them belong to extinct species. 



Sd, That with a single exception, all the genera to which these 

 fossils are referable, are now found inhabiting the Australasian 

 Continent, a remarkable coincidence with the fossil animals of 

 the same geological epoch in Europe, where, with few excep- 

 tions, the animals which have been found in what have been 

 called Diluvial Deposits, belong to genera still inhabiting our 

 countries. 



4^A, That the elephant was an inhabitant of New Holland 

 at no very remote period, as it appears to have been not only of 

 every part of the Old World, but of the American continent. 



In addition to the bones contained in Professor Jameson's 

 collection, I have since examined those sent to the Geological 

 Society of London, which belong to the same animals, with the 

 exception of a cervical vertebra of a large animal, little inferior 

 in size to a large deer, the extraordinary form of which has not 

 enabled me to refer it any known genus. 



Although I have attentively examined these several fossils, 

 I have not been able to discover any trace of gnawing of carni- 

 vorous animals, or of erosion produced by the motion of water 

 in conjunction with pebbles and rolled stones, as are frequent in 

 the fossil bones of our European caverns.

Analysis of' the Vibration of Wires. By Edward Sang, Esq. 

 Teacher of Mathematics. Communicated by the Author. 



iJuRiNG the past summer, Mr Addams exhibited, in this city, 

 a variety of interesting phenomena connected with vibration. 

 Not the least remarkable of these was one, first pointed out, I 

 believe, by Dr Wollaston, that of the formation of elegant tra- 

 jectories by the lateral vibrations of a wire. Unaware of the ex-
