constant attention. This compels the inhabitants of Sonf to employ the 
utmost activity, while giving them habits of industry has resulted in pro- 
curing them not^only competence, but wealth. All the houses are built of 
crystalline sulphate of lime, and are roofed with cupolas ; so that from a 
distance it looks like a collection of bee-hives. . . . It is a curious trait 
in the inhabitants of Souf that, having no other water than that of the wells, 
and this water never remaining on the sandy surface of the soil, thej^ have 
no idea of a brook, or a river, or any other kind of running water.” — Vide

A Neio Species of Plesiosaurus has lately been discovered by Mr. E. C. 
Day upon the Dorsetshire coast. The specimen was found between Char- 
mouth and Lyme Eegis, in a bed of marl intercalated between two of the 
uppermost beds of the lower Lias limestone : hence it comes from the 
middle of the zone of Ammonites Buchlancli. The fossil is thirteen feet in 
length, and exhibits the entire dorsal view of the skeleton with very few 
bones displaced. Besides the large head there is a very well-preserved jaw, 
filled with long curved teeth ; the cervical vertebrae exhibit well the 
characteristic pleurapophyses ; the dorsal vertebrae and the ribs are weU 
shown, and even the pelvic bones are in great part m their normal positions. 
The tail, too, is tolerably well preserved, and for the most part occupies its 
proper place ; but of all the parts, the limbs are those in the most complete 
preservation ; in fact, the four paddles with all their constituent bones remain 
just in the position they must have had when the animal ceased to live. We 
believe this specimen has been purchased by the authorities of the British 
Museum, and will soon be described by Professor Owen. 
The Glasgoiu School of Mines. — We regret to learn that this Institution is 
about to be abandoned, the anticipated subscriptions from the coal and iron- 
masters not having been forthcoming. This event has been long foreseen, 
and it is thought probable by those who have experience in such matters, 
that a similar fate may soon be expected to overtake two or three schools of 
a like character, which are now dragging on a precarious existence in some of 
our mining districts. 
Goal on the Southern Flanh of the Harz. — It seems not unlikely from the 
explorations of Herr Eoemer, of Clausthal, that a new coal field will be found 
on the southern flank of the Harz. The productive coal-measures are sup- 
posed to lie unconformably on the older Grauwacke rocks. The probable 
district lies about half way between the coal fields of Saxony and Westphalia, 
and it is thought that the result of mining exploration will be to show a very 
large deposit of coal of an excellent quality. — ^Yide Mining and Smelting

Indentations on the Bones of an Irish Blk.Some very curious marks have 
lately been observed by Mr. J. Beete Jukes, upon the bones and antler of 
Megaceros. The most striking of those seen were the markings on the tibia 
and antler tine. There were indentations about two inches broad and a quarter 
of an inch deep, and they seemed as if they had been each chipped out with 
some sharp instrument. The impression which they left at first on Mr. Jukes’s 
mind was, that these three indentations were the best evidence that had yet 
turned up in proof of man having been contemporaneous in Ireland with the 
Megaceros, and having left his marks upon the bones of an animal which he
