thickness, and that a very false impression might be conveyed 
by any error in labelling or describing the position of the 
specimens. Animal remains should be preserved for exami¬ 
nation at home, and for submission to a comparative anatomist, 
especially if the traveller is not one himself. 12 a. Pebbles 
showing any bruises or signs of wear should be brought awav, 
as well as more obvious relics. 13. Note the elevation of the 
mouths of the caverns above the existing watercourses, and 
give plans and sections when practicable. 
Neolithic (Surface) Period. —14. Implements of neolithic 
type are likely to be found in soil turned up by cultivation, 
or where the surface has been removed by rains, on the 
borders of plateau-lands overlooking a valley, near the 
margins of ancient forests, or in any place suitable for an 
encampment near water : attention may be drawn to such 
spots by observing the flakes, which are always abundant in 
places where stone implements have been fabricated. 
15. Note what class of pottery, if any, is found, with flakes 
and implements on the surface. 16. Notice whether the 
implements have been formed by chipping or by grinding ; 
if by grinding, look for the concave rubbing stones on which 
they were ground. 17. Notice any evidence that may exist 
of metal having been little used at the same time or subse¬ 
quently to the stone implements. 18. Preserve any bone 
implements or other relics found on the spot. 19. Should 
any implements be found with holes bored through them, 
notice whether the holes are cylindrical or enlarged towards 
the outside, from having been bored from the two sides. 
20. Preserve as many specimens as possible, and label them all 
at once , by writing with ink (or preferably lead pencil) upon 
the stones if possible ; take measurements and make outline 
drawings of any that cannot be carried away, and notice what 
animal remains are found with them. 21. The following 
illustrations of some of the principal types of neolithic 
implements found in this country are contributed by John 
Evans, Esq., F.R.S.
