Thus I have endeavoured, with as much accuracy as poffible, 

 and in as few words as I could, to ftate the particulars of this 

 extraordinary cafe, and at the fame time I have ftated the obferva-

 fuch as are to be found in a human jaw : Two of thefe teeth 

 grew together, whereas two others had grown feparately : But 

 what would aftonifh an obferver moft, fays he, is that the thigh 

 of a fmall African deer was found in the fame fac, and this thigh
