We figure these things that a subject of such universal 
inquiry may no longer remain in obscurity. Animal re-— 
mains, especially the more earthy, such as corals, have left 
such various impressions * that it requires many specimens 
and much experience to recognise them. 
The figure No. 1. is from Sussex. No.2. was sent me 
with some others by my kind friend Colonel Walford. 
No. 3. I found with others of the same sort at the Isle of 
Dogs. No. 4. shows the inside of the same, and No. 5. 
was picked up in a gravel pit at Kennington. 
* Some have considered these as parts of Mushrooms, such as Morels, &c. 
petrified, and I have one that has been compared to a marrow and bone; 
whichit much resembles in form, sent me by the Rev. Dr. Sutton of Norwich. 
J have another which I found near Dulwich, which might very well be 
taken for a petrified Agaricus, showing, as it were, the impressions of the 
edges of the lamelle, three or four inches in diameter and eight or nine in 
circumference.
