The following fossil remains, from 961 to 1116 inclusive, of a Horse, or of an 

 animal of the genus Equus, most of which indicate species about fourteen hands 

 high, were discovered by Joseph Whidbey, Esq., Civil Engineer, in the cavernous 

 fissures at Oreston, near Plymouth, and were presented, through Sir John Bar- 

 row, Secretary to the Admiralty, to the Royal College of Surgeons. They form 

 part of the specimens referred to by Dr. Euckland in the ' Reliquiae Diluvianse,' 

 pp. 72, 73 and 75, " Horse, about twelve, of different ages and sizes, as if from 

 more than one species : " in which work will be found a full description of the 

 caverns in the Oreston limestone. Cuvier was unable to fix upon any cha- 

 racters in the fossil remains of the genus Equus which he examined, proving 

 them to be specifically distinct from the existing Horse : he merely remarks that 

 the bones are not so large as those of our large Horses, but more approaching 

 the size of those of the Zebra. Unequivocally distinct species have since been 

 determined by fossil remains discovered in tertiary strata in Germany and India. 



961. The third or outer incisor, left side, upper jaw, of a species of Equus: 



the inverted cone of enamel, or ' mark,' which penetrates the crown of 

 the tooth had not been worn away when the animal perished. The outer 

 angle of the tooth is more produced than in the corresponding recent 

 tooth of the Horse compared with the fossil. 



962. The left upper canine of a species of Equus. 



963. The first molar, right side, upper jaw, of a species of Equus : the central 



enamel islands are rather more plicated than in the recent Horse, but the 

 anterior angle of the crown is as much produced. 



964. The second molar, right side, upper jaw, of a species of Equus. It is re- 



markably distinguished from the corresponding tooth in the recent Horse 

 by the more complicated and elegant plications of the central islands of 

 the enamel, as also by the greater proportional antero-posterior diameter 

 of the crown.
