to the specimens, together with a short description of the 
woods, as compiled for the catalogue of the exhibits of 
British Guiana at the Edinburgh International Forestry 
Exhibition. 
After examining these woods, the visitor is to go to the 
left hand side of the Museum. The obje6ls first seen are 
flint-implements from Florida, Honduras, Denmark and 
Prussia. They represent the older and roughly-chipped 
flints, as well as the later and polished specimens, used 
by man as tools and weapons in the early ages before 
metal implements w r ere made. A stone war-bludgeon from 
New Zealand is also shewn. Next to these are seen 
various chemical produ6ls obtained, by various modes of 
treatment, from crude coal-tar — a common waste produft 
in former years. They include the several varieties of 
carbolic acid, the various carbolised surgical prepara- 
tions, the different kinds of disinfecting powders, the 
splendid dyes such as picric acid, aurine, chrysophe- 
nolene, etc, and the various metallic carbolates, such as 
those of lead, lime, etc. A specimen of carbolic sugar, or 
saccharine, is, however, not yet included in the collection. 
On the next table is shewn a colonial colle6lion of the 
forms commonly known as Inse6ts ; but they include 
three distin6l types, such as : —

thorax and abdomen, by having three pairs of legs and 
one or two pairs of wings on the thorax, by the absence 
of limbs from the abdomen, and by the presence of air- 
tubes, or tracheae, for respiration, running through the 
body. 
(2). The spiders and scorpions (Arachnida) distin-
