These beds dip E.S.E. about 10°, and form part of an inter- 

 esting series which is well seen from Carham to Norham, and 

 on the banks of the Blackadder below Chirnside. Below Cold- 

 stream the sandstones abound in Lepidodendra, and fine speci- 

 mens of Stigmaria ficoides, with the rootlets attached ; and near 

 this locality, the remarkable remains of coniferous trees, with 

 the internal structure preserved, were first observed by Witham ; 

 and it is important to notice that along with these trees Mr. 

 Tate has found Ort/tocerata, Pieurotomaria, and Modiola, marine 

 shells, which prove that the coniferous trees had been carried 

 down into an estuary of the sea, and entombed and fossihzed 

 among marine exuviae. These beds form the lowest portion of 

 the Carboniferous formation lying below the Productal and 

 Encrinal Mountain Limestone of Northumberland, and might 

 properly be designated as the Tuedian group. They are distin- 

 guished by the peculiarity of the shales, by the thin beds of 

 magnesian limestone, by the absence of Brachiopods, and by the 

 presence of Modioli, Entoinostraca, and Fish-remains, Speci- 

 mens of these fossils were exhibited by Mr. Tate. The Rev. J. 

 Baird also exhibited specimens of the curious form of Ranunculus 

 auricomus, first noticed by him eight years ago, and during 

 which period it has been sought for in vain until the present 

 year. — The Rev. T. S. Goldie was proposed as a Member by Mr. 

 Melrose, and seconded by Mr. Rea. The day was extremely 

 beautiful, and spent in the usual enjoyments of kindly inter-* 

 course and feeling. 



The next Meeting was held at Coldingham, on the 25th of 

 June, and was attended by Dr. Hood, Dr. Stuart, Mr. Huggup,
