 believed that several species had been formel by observers out of 

 these different stages. StaphyJopteris was found also at West Calder ; 

 it is well known as occurring in the carboniferous rocks of Illinois and 

 Arkansas. — Prof. W. R. McNab gave an account of the structure of the 

 leaves of several species of Abies. These will be fully illustrated in 

 the "Proceedings" of the Royal Irish Academy. 



The meeting was attended by many English botanists, and by 

 Prof. Cohn, of Breslau. and Prof. Morren, of Liege.
