242 Dr Buckland on the Bones of Hyenas, tyc. 



conducted so close to each other. The uppermost rank being 

 most exposed to the direct influence of the sun, acted as a 

 shade to the lower ones ; it therefore expanded more than them, 

 and subsided so as to lay both its own weight, and its share of 

 that of the roadway, on the second rank. 



The workmanship of the chains and the whole detail of the 

 bridge seemed excellent, and it appears certain that, if the usual 

 methods of securing the ends of the chains had not been de- 

 parted from, this bridge would have continued to ornament 

 its beautiful site, and to be an honourable monument to the 

 learned engineer who planned it. 

 Length of the bridge from pillar to pillar, 170 metres = 557 ft. nearly. 



The width 9\ - = 31 ft. — 



Height of pillars above the roadway - 14 - = 46 ft.—— 



I am, Dear Sir, 



Your very obedient servant,

P. S. — A detailed account of this bridge, and much valuable 

 information, will be found in the interesting " Memoire sur 

 les Ponts suspendus, par M. Navier, Ingenieur en chef au 

 Corps Royal des Ponts et Chaussees" — Paris, 1823. 



Art. XII. — Observations on the Bones of Hyenas and other 

 Animals in the Cavern of Lunel, near Montpellier, and in 

 the adjacent Strata of Marine formation* By the Rev. 

 W. Buckland, D. D. Professor of Mineralogy and Geolo- 

 gy, Oxford. 



The cave of Lunel is situated in compact calcaire grossier, 

 with subordinate beds of globular calcareous concretions, and 

 the whole of the rock having something of an oolitic structure. 

 In working a freestone quarry of this calcaire grossier, the 



* Having already (No. viii. p. 378) published a short description of 

 this interesting cavern, as examined by M. Marcel de Serres, we are glad 

 to be able to give an abstract of Professor Buckland's account of it, which 

 was read at the Geological Society on the 17th November last. This 

 abstract is taken from the Phil. Mag. No. i. p. 66, Jan. 1827. Professor 

 Buckland visited the cave in March 182G, and has established nearly a 

 perfect identity between the cavern of Lunel and those of England.
