THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
EXCHANGE. 
“ Exchange is no robbery." — Oi.D Saving. 
‘■Robbery is no exchange." — New Saying. 
To the Editor of the ‘ Intelligencer.' 
Sir, — Now that the season has com- 
menced, a few remarks on the present 
“ Exchange ” system may not be out of 
place. 
Il is a slur upon our Science that 
there are meu amongst us who apply the 
principle of “ All fair in love and war” 
to Entomology, — that the ends justify 
the means, — men for whom the phrase 
“ Rem honesti si possis, sed rem,’’ might 
he conveniently shortened to “ rem ” 
alone, since honesty or honour have no 
part in their transactions. One cannot 
but pity the greedy mind, which, for the 
sake of a few insects, postage-stamps or 
boxes, will sacrifice reputation (if it have 
il), or all chances of ever getting it (if it 
have it not), — to say nothing of con- 
science, when present. 
Some have been unjustly — others 
hastily — accused ; now and then the 
accuser has been the culprit; not un- 
frequenlly the perpetration of a swindle 
has gone unpunished, while others have 
deservedly gained for themselves an un- 
enviable and lasting notoriety. 
My chief object in writing this letter 
is that the victims of these black sheep 
may no longer, from a feeling of modesty 
or timidity, be backward in denouncing 
men who do not deserve the name of 
entomologists. Barterers or sharp cus- 
tomers we cannot deal with, — they have 
a right to be so, if they please, — but 
swindlers it is a matter of common 
honesty to the public at large to expose. 
These lines may make a few enemies, 
but they will lose me no friends. 
Trusting that this may have the effect 
of removing that delicacy which always 
prevents our coming forward on such 
occasions, 
I am, Sir, 
Yours truly, 
H. G. Knaggs, M.D.

TINNING AND SETTING 
LEPIDOPTERA. 
To the Editor of the ‘ Intelligencer.' 
Sir, — I receive four boxes of insects, 
rare, bred and for the cabinet ; I open 
them successively, and in No. 1 find the 
insects pinned with the finest possible 
weapon, leaving a margin of about three- 
eighths of an inch above for the fingers 
and one-eighth of an inch below for the 
cork; consequently in inserting my prize 
beneath the label, so long a mere un- 
meaning symbol, down slips the pin into 
a paper-hidden vacuity in the cork, and 
my digits are driven into the thorax of 
Pet.asia nu'beculosa , at the same time that 
his legs are crushed against the cork. In 
no very satisfactory mood the remaining 
contents of the box are transferred to the 
mouldy perils of the relaxer to be re- 
pinned. 
Now for No. 2. What beauties! but 
what a marvellous curve their wings 
have, like those of a partridge, — very 
suitable to that bird, and perhaps to 
Cerastis Vaccinii, but scarcely appropriate 
to Plusia Bructca ; also what singular 
strite are on the wings of those Thccla 
W-album , — “ Set with thread for a Leu- 
cographa /” and I am not likely to lose 
my bet. 
No. 3 is a tremendous box — fourpence 
additional to pay. “ Open sesame,” and 
“Oh! skewers and pancakes!” here is 
Miana expolita on a spit fit lor the eye 
of Polyphemus, and Calocumpa vetnsta
