The No. for April, 1820, mentions, 
* A new Geological map of England and Wales, with 
the inland navigation, &c. &c.: By Wm. Smith, Engineer, 
on one large sheet, neatly coloured and shaded—Cary, St. 
James-st. price 14s.” 
*¢ Smith’s Geological Atlas, No. 3, is published by Cary. 
‘This work exhibits on separate maps, the Geology of the 
several counties of England and Wales.” 
Conite-—Dr. Mac Culloch mentions in his account of the 
_ Western Islands of Scotland, a new mineral, discovered by 
him, and to which he applies the name Conite, from the 
powdery form in which it occurs—he has since found it in 
the Kilpatrick hills, in trap, and also in Sky—the same 
name has been applied by Prof. Schumacher to a very dif- 
ferent substance; but Dr. M. thinks the latter is not hkely 
to maintain its place in our catalogue of mineral species, 
but it is peculiarly appropriate to his new substance. 
“ Emerald Mines.—M. Caillaud’s account of his discov- 
eries in Egypt will shortly be published in Paris. Some 
time ago he discovered near Mount Zabarab, the famous 
Emerald mines, which were previously known only by the 
writings of the ancient authors, and the stories of the 
Arabs”—* they were discovered by M. C. nearly in the 
same state in which they had been left by the engineers 
of the Ptolomies. He penetrated into a vast number of 
excavations and subterraneous canals, some of which are 
so deep that four hundred men may work in them at once. 
In the mines were found cords, levers, tools of various 
kinds, vases and lamps; and the arrangement of the works 
afforded every facility for studying the ancient process of 
mining. M.C. himself set about working the mines, and 
he has presented six pounds of emeralds to Mahommed 
Ali Pashaw.”—‘‘ On the banks of the Red Sea, the same 
traveller discovered a mountain of sulphur, on which some 
diggings had been made; in the neighbourhood of this 
mountain traces of volcanic eruptions were observable, and 
a quantity of puzzolana, and other igneous substances was 
found.”—‘ He returned last year to Paris, bringing a vast
