fact that in all drift specimens there exists a marked general 
resemblance, whether these implements were designed as useful 
tools, or destructive weapons of war, or of the chase. This typical 
likeness is quite independant of the locality from which they are 
derived, and applies with equal force to those obtained from the 
furthest removed French beds and the most northern deposits of 
this country. And yet it is remarkable that in spite of this family 
likeness, certain slight but well marked individual characters exist 
in each separate locality, and may be observed even in spots so 
near together as Milford Hill and Bemerton ; so much is this the 
case, that on first seeing a newly discovered specimen, the site from 
which it was obtained has been correctly assigned to it, from this 
circumstance alone. 

INSTRUCTIONS FOR THE 
—— formation of 2 Wiiltshive Herbarinm. 
By Tuomas Bruczs Frower, M.R.C.S., F.L.8., &e., &e. 
N a previous number of this Magazine (vol. iv., p. 191), it 
was proposed to commence the formation of a “County 
Herbarium” for future reference and study ; resident botanists were 
particularly invited to collect and dry for the Society, duplicates of 
such Wiltshire plants as they could conveniently spare, in order 
that they might be preserved and deposited in the Museum. With 
a view therefore of carrying out the above object, and for the 
guidance of those botanists who might feel disposed to contribute 
plants for permanent preservation in the herbarium of the Society, 
the following explanatory suggestions, regarding the illustration 
and labelling of specimens have now been drawn out. 
The first object with any herbarium whether local or general, 
should be to show the species. A fair typical specimen of each 
species is the leading idea to be met, and it will very usually be 
found needful to have more than one single specimen, because the
