near Gainsborough ” established the identification of the deposits in 
question with the Rheetic beds of the Continent, and thus gave to 
this formation an extension northwards beyond that it had been 
previously known to possess. 
Mr. Seeley, in illustration of his communication on “The 
Character of Dolichosaurus, a Lizard-like Serpent of the Chalk,” 
submitted to the Section a beautiful specimen of the fossil. His 
general conclusion was that it was a new type of creature between 
the serpent and the lizard. 
In Mr. Walker’s paper on “ The Lower Green Sand of Bedford- 
shire,” some account was given of the occurrence of phosphatic 
nodules in a conglomerate supposed to represent both the Gault 
and the Shanklin Sands, and which occurs near Sandy. 
From Mr. Mitchell’s “ Report on the Alum Bay Leaf-bed,” it 
appears that this bed is the band of white clay occurrmg in the 
Lower Bagshot beds in Alum Bay. It is about six feet thick, but 
one portion only, a few inches in thickness, contains the plant 
remains. No other fossils have been noticed. When first ex- 
humed, the outlines and even the most delicate venation of the 
leaves are clearly visible; but a few hours’ exposure to the air 
obliterates the more delicate marks. About 470 specimens have 
been obtained. 
Closely related to the subject of this paper was that by the Rey. 
Professor Heer, “‘On the Miocene Flora of North Greenland.” 
Different voyagers have, from time to time, brought from Green- 
land, and lodged in various museums in Britain and Ireland, rich 
collections of fossil plants, all of which have been submitted to Dr. 
Heer.. They were all found 1,080 feet above the sea, on a steep 
hill, at Atanekerdluk, opposite the Isle of Disco, in lat. 70° N. A 
total of 66 species have been recognized, and from them and their 
associated facts, the author infers that they must have grown where 
they were found ; that they belonged to a Miocene flora rich in 
species, at least some of which extended to still higher latitudes ; 
that in the Miocene epoch the climate of North Greenland was 
warmer then it is at present by fully 16° C., or 28°8° F.; and he 
thinks that “we could not by any re-arrangement of land and water 
produce for the northern hemisphere a climate which would explain 
the phenomena in a satisfactory manner.” “We must only admit,” 
he adds, “ that we are face to face with a problem whose solution m 
all probability must be attempted, and we doubt not completed by 
the astronomer.” 
Mr. Taylor, in his “ Relations of the Upper and Lower Crags, 
near Norwich,” contended for the existence of four separate ‘‘ Crags,” 
—the Coralline or most ancient, the Red, the Norwich, and the
