other appearance than that of the surrounding stone. 
Fig. 1. A side view of a specimen detached from the 
gritstone, in which it was found. 
2. rhe larger end of the same specimen. 
3. A piece of gritstone; one side broken away, so as to 
show the nut which lies in the centre. These figures are 
about the size of the original. I have now and then, how- 
ever, met with much larger specimens. 
4. A smaller specimen, adhering to a piece of fine, 
light-coloured grit. 
5. A nodule of Ironstone containing another specimen of 
the same fossil. In this there are evident traces of the rind 
oi covering, which once surrounded the nut : it seems to 
have been of a considerable thickness, and, as hr as can be

the diminutive size of the fruit— In the quarry above mentioned, however 
no other vestage of the plant was discovered, that could lead to the know’ 
ledge of its genus.
