dufky brown colour, refembling that of the ftone, in 
which it is bedded. 
One half of the bone is buried in the flone ; yet 
enough of it is expofed to lhew, that it is the thigh- 
bone of an animal of greater bulk than the larged; 
ox. I have compared it with the recent thigh-bone 
of an elephant ; but could obferve little or no re- 
femblance between them. If I may be allowed to 
a flume the liberty, in which foflilifts are often in- 
dulged, and to hazard a vague conjecture of my 
own, I would fay it may probably have belonged to 
the hippopotamus, to the rhinoceros, or fome fuch 
large animal, of whofe anatomy we have not yet a 
competent knowlege. 
The flate-pit, in which this bone was found, is 
about a quarter of a mile north-well; from Stones- 
field, upon the declivity of a riling ground, the 
upper ftratum of which is a vegetable mould about 
eight or ten inches thick : under this is a bed of 
rubble, with a mixture of fand and clay, very coarfe, 
about fix feet deep, in which are a great number of 
anomice both plain and ftriated, and many final! ob- 
long ovfters, which the workmen call the flckle- 
oyfter, fome of them being found crooked, and 
bearing fome refemblance to that inftrument but 
all differing from the curvi-roflra * of Moreton. 
Immediately under this ftratum of rubble is a bed 
of foft grey ftone, of no ufe ; but containing the 
echini ovarii , with great mantilla , the clypeati of 
different fizes, all well preferved ; and alfo many 
anomice and petti nes. This bed, which is about fe-
