PRESERVATION OF INSECTS- 
I venture to draw the attention of 
.entomologists to several communica- 
rtions, which have appeared in some 
of the monthly serials, concerning 
improved methods of preserving 
cabinet collections of insects, and 
which communications I regret to 
find have remained unnoticed by 
those subscribers to this journal, 
who favor it, from time to time, 
with communications containing 
much useful information. It is also 
worthy of mention, that the subject 
has called forth no observations in a 
valued monthly contemporary — the 
more comprehensive “ Zoologist.” 
It is a matter of surprise that 
so much apathy should apparently 
exist in regard to this question. It 
can scarcely be said in extenuation, 
that we are satisfied with the results 
of our present system, seeing that, 
notwithstanding a strict adoption of 
the instructions laid down in all the 
text books, to wit : a well seasoned 
cabinet, the driest situation the 
house will afford, and drawers well 
supplied with camphor — we are 
continually complaining that our in- 
sects become greasy, that a subtle 
mildew will creep in, and that living 
insects revel destructively amongst 
our much prized dead ones. Nor is 
this all ; most of us, I think have 
experienced, after all the care 
bestowed, a sad feeling of disap- 
pointment when comparing the 
shrivelled condition, and faded 
colors of many of our transfixed 
specimens of our cabinets with the 
plump and rounded forms and natu- 
ral colors of their living counter- 
parts. Of a surety we have no 
reason to feel at rest, or to congratu- 
late ourselves on the progress made
