Ekmenfcn-i/ Geological Collections ; and Geolorjical and Entomolofjieal Cahinefs. 
Issued by the Naturalists' Association for the Advancement or 
Science, 17, Dean-street, Soho, London. 
A'o. 47.— Small box with lifting trays coutauiiug a collection of ninety speci- 
mens of mmcrals classified and arranged according to tlieii- chemical bases. 
No. 48. — The like collection bound in two volumes. 
No. 15.— Geological Collection of Kocks and Fossils, containing about 120 
specimens illustrative of the Palaaozoic, Mesozoic, Cainozoic, the Igneous and 
Volcanic rocks. ♦ , . , 
Cabinet No. 10.— Contamiiig six drawers for Entomological, Geological, or 
otlier coUcctions. i r -i 
__JVVe inspected these cabinets and the selections of minerals, rocks, and fossils 
witii much pleasure, because pains liave been taken to get them up tastefully, 
cheaply, and well. Tlie specimens of cvcuthe smaller elementary colLlcc;tion.-, are 
sufficiently large to display the general characters of the objects. The geol9- 
gical collection of rocks. No. 1.5, is formed of pieces ahnost large enough to be 
termed hand-specimens ; wliile the common typical fossils with which these 
are interspersed give additional value and interest to the series. 
The small cabinet. No. 10, is a very tasteful affair. The door and the 
drawers being veneered, it presents quite a drawing-room appearance. It is 
well adapted for small coUcctions of insects, or very select fossils, and is one of 
a scries of cheap cabinets, which will supply a long-dcsii'cd want amongst ama- 
teur naturalists. 
lu one instance, in No. 48, we detected two wrong minerals; but this is ap- 
parently oidy a misplacement in their respective spaces of Oxide of Manganese 
and Ohgist Iron, as in the same collection bound in book-like cases, these minerals 
arc correctly placed. In the list of strata the granite and some otlier rocks are 
(contrary to some classifications) very properly and correctly grouped together 
with the intrusive rocks. 
Altogether these selections are very creditable and very faii-ly reliable.
