no certain evidence as yet that any of these impressions were made 

 by four-footed animals, although, in respect to two or three species, 

 I have strong suspicions that such was the fact. I have sometimes 

 thought they might have been made bv pterodactyles ; yet they 

 have in general fewer toes than those described by Cuvier and Buck- 

 land. Within a few weeks past I have found on the flag-stones, in 

 the city of New York, some marks, which I suspect were made by 

 the feet of a didactylous quadruped, which, like the Marsupialia, 

 moved by leaps. The rock is slaty graywacke, from the banks of 

 the Hudson, between Albany and the Highlands." Drawings of 

 these marks, with the tracts of living birds, have been prepared, and 

 will be published so soon as the localities are again examined. — Sil-

Blysmus Compressus. — I was not aware, until informed by my 

 friend, the Rev. W. Wood, that this plant had been found in the 

 neighbourhood of London, (not having seen any station for it.) It 

 is, however, most plentiful in a bog at Beddington Park gate, near 

 Carshalton, Surrey. — Daniel Cooper.
