Rocks, as mentioned in the latest edition of the ‘‘ Microscopic Physiography 
of Rocks,” by H. Rosenbusch (Stuttgart, 1896). 
Toeach one will be added a printed short description of all the Speci- 
mens and Slices, in order that the student himself might be able to recognise 
and determine the constituents of the Rock. 
Collections of 120, 180, and 250 Thin Slices. Price, in 
Elegant Cases, £7 1os., £11 5S., £16 5S., respectively.

spectively. 
As all thin Slices will be microscopically examined before being delivered, 
we can guarantee their perfect reliability, and that they exhibit all the 
characteristics of the rocks, as mentioned in the above-named description.
