Coal-mine in Styria," by Professor Anker, of Joanneum in Gratz, 

 was then read. 



The bones referred to by the author, were found in a range of 

 hills near Gratz in Styria, extending in a southerly direction from 

 the foot of the Schwamberg mountains to Scheineck on the Weiss. 

 These hills consist of molasse, alternating with beds of brown coal 

 from 2 to 2+ feet in thickness, which closely resembles black coal 

 in appearance, and can be distinguished from it only by geological 

 position, and by the occasional occurrence of the woody texture. 

 Associated with the coal are beds of bituminous shale, and a grey, 

 bituminous, marly, slaty sandstone, in which are occasionally inter- 

 spersed pebbles of primary rocks. 



The bones were found in the coal itself, in layers from 2 to 2-§- 

 inches thick. They were for the most part so much shattered, that 

 no notion could be formed of the genus of animal to which they be- 

 longed ; but from their great number, they appear to have been 

 derived from many different animals ; and after long-continued 

 search a jaw-bone with teeth was discovered. This specimen is pre- 

 served at Joanneum; but from the inspection of a drawing of it sent 

 with this notice, Mr. Clift considers that it belonged to a hyaena. 



Bones were first found in this mine in the year 1826, in the Jo- 

 seph adit, 50 fathoms from its mouth. They have been often met 

 with since that period in the same adit; and in 1831 bones were 

 also discovered in the Caroline adit of the same mine, 3 fathoms to 

 the south of the former. Among them was a tooth like that of a 

 shark, together with fragments of bones similar to those from the 

 Joseph adit ; but they were principally found in the strata adjacent 

 to the coal.

A paper, entitled "Geology of the Environs of Bonn," by Leonard 

 Horner, Esq. F.G.S. F.R.S. &c, was read. 



The district described by the author lies on both sides of the 

 Rhine, — the Siebengebirge, or Seven Mountains, constitute the 

 chief feature ; and the highest point in the group, the Oelberg, is 

 1369 English feet above the level of the sea. It possesses peculiar 

 interest to the geologists of England, as being the nearest point 

 where volcanic phenomena, approaching in character to those of 

 modern times, can be seen. 



The lowest stratified rock is grauwacke, which seems to belong 

 to the later ages of that deposit, and to approach in character, in 

 some parts of the district, to the old red sandstone. There are 

 no associated beds of limestone. The strata are in general highly 

 inclined, but they are found at all angles; and there is neither uni- 

 formity in the strike nor in the dip ; the strike is most usually N.E. 

 and S.W., the dip more frequently S. than N. In the immediate 

 neighbourhood of the Siebengebirge, the strata are thrown up in all 

 directions, evidently by the eruption of the volcanic matter. 



The whole of the later secondary series is wanting, and the
