As soon as Professor Heer had given his judgment respecting 
the Era of the Bovey Lignites, I requested Mr. H. Keeping, who 
had returned to the Isle of Wight, to devote some time on my 
account to a specified well-defined zone in the Hempstead beds in 
that Island, and to send me such plant remains as he might meet 
with. A few weeks brought a good series of specimens, which 
were at once forwarded to Professor Heer, who identified them as 
belonging to ten species, all new to the Island, four of them 
identical with Bovey species, and two new to Science.
