Note. — I have the authority of Mons. Adolphe Brongniart for stating that he considers the fossil 

 plant of the Brora coal, which Mr. Konig has described as Oncylogonatum carbonarium (ante 

 p. 300), to be a species of Equisetum which he has named Equisetum columnare. It is figured 

 in M. Brongniart's new history of vegetable fossils (vol. I. Plate xiii.), and will be described in 

 the forthcoming number of that work. This plant, which appears to be generally characteristic of 

 the inferior oolite, and which has never been discovered among the vegetables of the ancient coal 

 measures, has been found at Balbronn, department of the Lower Rhine — in the neighbourhood of 

 Stutgard — and even at Baldissero in Piedmont. Specimens from these localities are now in the 

 museum at Strasburgh, and are all in the same compressed state as those in the shale at Brora. —
