mandible near the extremity was covered with a fhelf 
of the rook about three inches thick ; which being 
cut away and removed both the mandibles appear- 
ed under it compleat, with the teeth of the upper and 
under one, plainly locking or palling by each other. 
Thefe appeared to be of the dentes exert i or fang 
kind, as well as all the others in the narrow part of 
the mandible, and further backwards they were not 
obferved. From this ledge or fhelf the mandible 
towards B is fingle, and appears to be the upper one 
of the living animal ; and from the head not being 
exactly in the line of the body, that part has been 
inverted, or quite turned over, and the body itfelf, as 
appears from the tranfverfe procefles of the vertebra 
lies on the right fide. There appears one row of 
teeth only on each fide of the mandible, and they 
are about -f of an inch afunder. 
The mandible B A, the cranium g h i and the ver- 
tebra from D to F, were attempted to be taken up 
whole ; but the bones being rendered extremely brittle, 
and the rock in which they were fixed being a brittle

only, which makes them eafy to join together again, 
and befides fhows very plainly the tranfverfe and fpi-
