he demonstrates by figures, that the tertiary formation — a horizontal marine 

 deposit — is more recent than the valleys in which it has been deposited." 



This work is a new proof that, if the present age is fertile in ingenious 

 views and theories, we ought to be very circumspect in our claims to priority 

 of ideas, which we are naturally too often inclined to claim for ourselves or 

 our friends, without having sufficiently examined the annals of the science. —

Discovery of Fossil Bones in Australia. — Mr Barrow communicated to a 

 late meeting of the Royal Geographical Society, the discovery of a great 

 quantity of fossil bones of quadrupeds, of very large size, in Wellington 

 Valley, near the Blue Mountains. At present there are no large quadrupeds 

 in New Holland. If this island be postdiluvian with respect to what is 

 called the general deluge, as has been supposed, there seems, from these 

 circumstances, to be evidence of its having since experienced a local fiood. 



Fossil Sheik on the Snowy Mountains of Thibet At a meeting of the 



Asiatic Society of Calcutta, on 3th May last, extracts from Mr Gerard's 

 letters, relative to the fossil shells collected by him in his late tour over the 

 snowy mountains of the Thibet frontier, were read. The loftiest altitude 

 at which he picked up some of them, was on the crest of a pass, elevated 

 17,000 feet : and here also were fragments of rocks, bearing the impression 

 of shells, which must have been detached from the contiguous peaks rising 

 far above the elevated level. Generally, however, the rocks formed of these 

 shells are at an altitude of 16,000 feet, and one cliff was a mUe in perpendicular 

 height above the nearest level. Mr Gerard farther states, " Just before 

 crossing the boundary of Ludak into Bussalier, I was exceedingly gratified 

 by the discovery of a bed of fossil oysters, clinging to the rock as if they 

 had been alive." In whatever point of view we are to consider the subject 

 it is sublime to think of millions of organic remains lying at such an 

 extraordinary altitude, and of vast cliflfs of rocks formed out of them, 

 frowning over the illimitable and desolate waters, where the ocean once 

 rolled. — Asiatic Register. 



Galena Calamine. — Mons. Bone states, that galena and calamine are 



found in the Alpine limestone (Calcaire Alpin) of Germany, both in the 

 masses which are above, and in those which lie below the salt. — Ibid, p. 302. 



Phosphates of Iron and Manganese — Huraidite — Hetepozite. — M. Du 

 Frenoy has published a new analysis of these lately discovered minerals, 

 differing in some respects from the previous analysis of Vauquelin. These 

 analyses we subjoin, in connection with that of the common phosphate of 

 iron and manganese, made formerly by Berzelius, by which means the 

 difference of constitution of the three minerals will be distinctly seen : —

These new minerals, like the common phosphate, are found in the granite 

 at Limoges. The hetepozite is found only in lamellar masses, having three 

 distinct cleavages, giving for the primitive form an oblique rhomboidal 

 prism of 100 or 101 degrees. The huraulite has been found in small 

 rhomboidal prisms, with an inclined termination, joined together laterally 

 like the crystals of stilbite. It is reddish yellow, transparent; has a 

 glassy fracture, but exhibits no cleavage ; scratches carbonate of lime, but is 

 scratched by steel, and has a specific gi-avity of 2.27. Before the blow-
