since the deposition of these beds, either by the elevation 

 of the mountains, or the depression of the valleys, or the 

 united effect of both these causes, the relative level of the one 

 to the other has been changed to the amount of many thousand 

 feet. 



March 4. — A notice was read on some silicified wood from 

 the desert between Cairo and Suez, in a letter by George 

 Francis Grey, Esq. to the Rev. W. Buckland, Pres. GS. 



Large masses of silicified wood, resembling in form the 

 trunks of palm trees, lie scattered, the author observes, over a 

 tract of gravel in the desert about fifteen miles from Cairo, and 

 for two days' journey all the way from that place to Suez. 



A notice was also read on the bones of several animals found 

 in peat near Romsey, in Hampshire, extracted from a letter 

 from Charles Daman, Esq. to the Rev. W. Buckland, Pres. GS. 



Mr. Daman mentions that the skulls of several beavers, as 

 well as the bones of oxen, swine, stags and roebucks, have 

 been dug out of the peat near Romsey, and out of the shell 

 marl provincially termed " malm," which occurs in the same 

 alluvial tract. In one place several human skeletons have been 

 taken out of the marl. 



A paper entitled " Observations on the beds of clay, sand, 

 and gravel belonging to the red marl formation of the midland 

 counties, and on the rocks from which they are derived, by 

 the Rev. James Yates, MGS." was read in part. 



March 18. — The paper entitled " Observations on the beds 

 of clay, sand, and gravel belonging to the red marl formation 

 of the midland counties, and on the rocks from which they are 

 derived, by the Rev. James Yates, MGS." was concluded. 



In this communication Mr. Yates enters into some description 

 of the rocks which are found in situ on the confines of Wales 

 and Shropshire, in order to show, that from the disintegration 

 of these rocks, the clay, sand, and gravel of the red marl for- 

 mation have for the most part been derived. The first line of 

 section which is particularly considered is near the river Dee 

 and Valle Crucis ; the second, a line drawn from Oswestry 

 westward to Llansilen, which crosses within the space of five 

 miles the basset edges of all the strata from the new red sand- 

 stone to the slate. The author then takes a view of the rocks 

 occurring in the direction of the road from Welchpool to 

 Ludlow. The fourth district then noticed is the vicmity of 

 Church Stretton. Mr. Yates then mentions some particulars 

 of the rock near Bewdley, and in the Clent hills, and the 

 neighbourhood of Dudley, and adds some remarks on the 

 Broomsgrove Lickey, as supplementary to Professor Buckland's 

 paper in the Hfth volume of the Geological Society's Trans- 

 actions.
