PLATE 8, 9. 
FIG. 4. 
PHYTOLITHUS (compressus) Radicis? simplicis co- 
lumnaris compressae, longitudinaliter rugatas. S. t. 
A fossil vegetable. The original a root ; simple, colum- 
nar, compressed and longitudinally wrinkled. 
The compressed form of this petrifaction appears to have 
been received from the original; the species last described, 
being found in the same stone perfectly round. 
Frequent in gritstone. The specimens, fig. 2, 3, and 4, 
were collected from a small quarry between Buxton and 
Leek. I have lately met with much larger specimens, near 
C}*apel~in-the-Frith .
