Pagina lxi - ... whole land, as well as its limitations during a later period, when it had begun to wane. In order to advance across a hilly country and over mountainous ridges rising to a height of twelve and fifteen hundred feet in the southern part of the State, and to a much higher level in its northern portion, the ice must have been several times thicker than the height of the inequalities over which it passed ; otherwise it would have become encased between these elevations, which would have acted as walls...

Pagina xvii - To promote researches concerning the mineral structure of the earth, and to enable the Council of the Geological Society to reward those individuals of any country by whom such researches may hereafter be made,' — ( such individual not being a Member of the Council.
Pagina liv - They were then in latitude 76° 12' south, longitude 164° east, the dip 88° 40', and ' were therefore only 160 miles from the [magnetic] pole.' On the 25th, as Ross relates, ' we had a good view of the coast. The whole of the land being perfectly free from cloud or haze, the lofty range of mountains appeared projected upon the clear sky beyond them beautifully defined ; and although of a spotless white, without the smallest patch of exposed rock throughout its whole extent to relieve it, yet the...

By James Buckman, Esq., FLS, FGS In this paper the author discussed the true position of certain beds containing abundant remains of Cephalopoda, found in various parts of the Jurassic region of this country, and of the sandy bed underlying the Inferior Oolite at Cleeve Hill and other places (called" by Prof. Phillips the " Midford Sands "), which has been regarded by most authors as belonging to the Lias. From an investigation of the Cephalopoda-bed in quarries...
Pagina 76 - ... assumed that in process of time this highly complex organic substance would decompose, its organic constituents would be evolved, and its silica would remain behind. In such a way flints might be produced, and dialysis would lend its aid. The same explanation was applied to account for the connexion between calcic phosphate and animal matter in the case of the

Pagina 76 - ... known facts of chemistry. The author's explanation was not intended to be final. The first fact pointed out was the very remarkable way in which the silica or calcic phosphate of the fossils under consideration followed the former extension of organic matter. This was explained for silica by the fact that, when silicic acid is added to such animal matters as albumen or gelatin, it forms with them a definite chemical compound...
Pagina 421 - The specimen described showed the outline of a small Starfish, with a large disk and short rays, in a slab of Wenlock Limestone from Dudley. The outline of the ten rays was described as marked out by the border of small triangular spines, the other plates of the disk and rays being absent. Each ray was terminated by a stemlike multiarticulate process as long as the ray, from towards the extremity of which spring slender lateral processes, giving it a tufted appearance. This Starfish, which is in...
