14. A convenient method of storing Butterflies in Paper 
Envelopes.*—Triangular paper envelopes have been employed by 
travelling entomologists for the temporary storage of butterflies, 
for many years. But it has been usual to lay these envelopes 
haphazard in plain boxes, in such a manner that it is impossible 
to find any particular specimen without turning over the whole 
contents of the box. | 
By the use of the special boxes here described the envelopes 
occupy very much less space, the contents are less liable to damage, 
and any individual specimen can be found and removed with the 
greatest ease without disturbing the remainder. 


“of 
The boxes are made of tin plate, with partitions dividing them into 
trough-shaped spaces. The envelopes rest edgeways in the troughs. 
The boxes are fitted with two lids, above and below. 
Fia. 4. 
Fig. 4 shows a box with the upper lid removed and the lower one 
in place. The box measures 9 in. by 6in. by 3in. The upper space 
contains a single trough (a), and carries envelopes with a base of 
5? inches.
