first to reduce it into small pieces (not 
into powder), then to enclose it in a small 
bag, made of any porous material, aud 
place the bag with its contents at the 
bottom of the bottle, aud on this a per- 
forated card rounded to fit tightly the 
bottle, to preserve the bag firm at the 
bottom of the bottle. The ammonia 
gradually separates from the carbonic 
acid and fills the bottle sufficiently strong 
to effect the object. — T. Tide motif,

Remedy for failure at Sugar. — In 
Shield’s ‘Practical Hints’ it is recom- 
mended to use essential oil of bitter 
almonds in the mixture during the time 
that the almond tree is in blossom. Why 
should not a similar plan be adopted 
with respect to all the attractive trees 
throughout the year, and have essences 
or odoriferous preparations of some kind, 
of such plants as honeysuckle, rhododen- 
dron, ivy, &c. ? By this plan we might 
at any rale modify the effects of such 
a profusion of blossoms as that of the 
present year. — J. F. Moon, Hyde ; Nov. 9. 
Cheap Substitute for Cork .— -About six 
months ago one of your correspondents 
was kind enough to inform your readers 
that £20 was too much to pay for a full 
size British cabinet, and mentioned the 
cost of one made of the best materials as 
£3 15s.; but still this was to be exclu- 
sive of the cork, the cost of which, in a 
cabinet of thirty drawers, each 14 inches 
square, will not come much short of £2, 
a sum which many can badly afford. A 
cheap substitute was told me by a person, 
a little while ago, which, on trial, I find 
to answer quite as well, and not costing 
the tenth part. Get some new ironing 
blanket (if common blanket two folds are 
required), glue this well to the bottom of 
the drawer; then, soaking it well with 
paste, cover it with paper, which must 
not be too thick, or else it will not lie 
well to the blanket, which will also happen 
if enough paste has not been put on the 
latter. — R. Tyree, jun., Row Lane, South- 
port ; Nov. 7. 
Sphinx Convolvuli in June. — I have 
just placed in my collection a specimen of 
S. Convolvuli, which w as taken by a per- 
son at Maidstone on the 21st of June. 
The insect was taken at night while at 
rest upon some ivy. I should not have 
written this had 1 not been struck by the 
earliuess of its appearance, more than 
two months before the time mentioned 
in the ‘Manual.’ Have any of your 
dragon fly correspondents tried oxalic 
acid for clearing out the intestines? It 
has answered pretty fairly in keepiug the 
colour of a fly I captured. — Syoney 
H astings, 14, Albemarle Street ; Nov. 2. 
Ilow should one collect the Pupa of 
Machaon ? — Can any of the readers of 
the ‘Intelligencer’ inform me how I 
should go to work to collect these pup® 
during the winter? I have many more 
applications for them than I can supply.

Capture of Argynnis Dia. — A short 
time ago, among some insects brought 
me to name by a young collector, the 
Hon. C. A. Ellis, resident near here, I 
observed a small Fiilillary unknown to 
me: it had been knocked down by a vil- 
lage lad with his cap, and was pinned 
and set in corresponding style ; still I 
insisted on its interest, and recommended 
that it should be sent to Mr. Doubleday 
to name. He has pronounced it to be 
Argynnis Dia, and, through the liberality 
of Mr. Ellis, the specimen is now in my 
collection. This fact will give deserved 
pleasure to Mr. Richard Weaver, whose 
capture of Dia near Sutton Coldfield, 
years ago, thus receives confirmation in 
Berkshire. — Rev. B. Smith, Marlow; 
November 7. 
Parasitic Acari. — During the past sea- 
son I have repeatedly observed these on the 
thorax of the common Crane Fly ( Tigula 
Horlorum) at Wickham. — C. Hkaly,
