And accordingly we see those methods which profess to supersede the necessity of chemistry in mineralogy, and to decide upon the...

Seite 187 - Vierzon, and Blois, as in each of these places it was the cause of some alarm, and was attributed to the explosion of a powder-mill. It is concluded, that, in consequence of the great distances in the circle in which the noise was heard, the explosion took place at a height in the atmosphere almost incalculable. The stones were found within an extent of half a league of each other , and their fall, in a perpendicular direction, was without any apparent light or globe of fire attending them. One of...
Seite 249 - That the whole of this extensive country, from the falls to the coast, is factitious, and of Neptunian origin, appears far from being hypothetical ; and the fossil teeth and bones, which accompany this memoir, and which with many hundred more, were dug out of a well at Richmond from the depth of 71 feet, prove that the deposition of the super-strata is not of a date sufficiently removed to have destroyed the soft and almost cartilaginous part of the joints, or to have injured the enamel of the tfelli.

A magnifying glass discovered a few minute pores, but not the slightest earthy appearance. This experiment was repeated several times and with uniform success ; may not lime therefore be added to the list of fusible bodies f Clark, page 47.
Seite 207 - Beryl melted instantly into a perfect globule, and continued in a violent ebullition, as long as the flame was applied ; and when, after the globule became cold, it was heated again, the ebullition was equally renewed : the globule was a glass of a beautiful bluish-white colour.
Seite 188 - Mortelle, it seems had not been found. Another fell at Villeroi, and the third at Moulinbrule. One of them weighed twenty pounds, and made a hole in the ground, in a vertical direction, just big enough to bury itself, at the same time that it threw up the earth eight or ten feet high. This stone was taken out about half an hour afterwards, being still hot enough to be held in the hand with some difficulty. It diffused a strong scent like that of gunpowder, which it retained till it was perfectly...

It is higher nearer the sea, the inner edge being rounded off, and I think at its highest point, it cannot be less than 100 feet above highwater mark. If the hills advance at an equal ratio for 20 or 30 years more, they will swallow up the whole swamp, and render the coast a desert indeed, for not a blade of grass finds nutriment upon the sand. Should this event take place...
