III Buttfiiflics, Moths, &c. in Ihecaliinet, after they 
have been fastened down, by means of a pin run thronjjh tlie 
t :orax, the wings on one side slionld be expanded, and a nar¬ 
row stn|) of card laid over them, which should be fastened 
down at l.oth ends !)y pins, so as to retain the wings in their 
position, the other side must then he ticated in the same way 
(fig. 10) the legs and antennai must then be placedproperly, and 
the insect left for a few days to dry, when tlie cards may here- 
moved, and the wings will afterwards remain as they were 
fixed. In these operations, a small needle and hook, (ng. 17) 
ecured in wood handles, will be useful.

In the larger Moths, it will be necessary to remove the viscera, by means of the hook, and 
to till up the body with cotton-wool moistened with the following mixture:— 
Corrosive Sublimate,.I drachm, 
Rectified Spirit of Wine,.1 ounce. 
This should also be applied, by means of a hair pencil, to the under parts of the insects, (which 
should afterwards be left a short time to dry) before they are finally fixed in the cabinet; in 
order to prevent their destruction by minute insects, such as and Acarus destructor, 
w'hich would soon destroy a whole collection. 
The cateri>illars of the Death’s-Head Hawk-Moth, Acherontia atropos, may be found occa¬ 
sionally, feeding on the potato, at night, though they are concealed in the day, beneath the 
under leaves or in the soil. They are remarkable for their size, being sometimes found five inches 
long, and are furnished with horns and tail. They should be placed in a flower-pot filled with 
mould, and covered with gauze-net, as they undergo their transformation in the earth. 
The Painted-Lady Butterfly, Vanessa cardui; and the Red Admirable, V. atatania; may 
frequently be seen on decaying fruit on walls. The Copper Butterfly, Lycaena phlceas; the 
Brimstone Butterfly, Gonepteryx rhamni; the Saft'ron Butterfly, and some other 
kinds may also still be occasionally met with. 
’I'he webs of the Gossamer Spider, Aranea ohtectrix, the manner of producing which, has 
been the subject of so mucli curious disquisition, and controversy may now be seen, particu¬ 
larly on a fine morning, after a fog, covering the fields, hedges, bushes, and pathways, in all 
directions, and appearing like strings of small pearls. 
ORJJITHOLOGY. 
(Most of the summer birds of passage now leave us, as the Wryneck, Yunx toryiiilla; tlie 
Red-start, Sylvia P/iaeniciiriis the Blackcap, Silvia atricapilla; the White-throat, Sylvia 
cinerea; Wim hat Sylvi( rubetra- the Swallow, Hirundo\rustica\ the Spotted Flycatcher, 
jMuscicapa (jrisola-,vi\\A the Common Sandpiper, Trinya hypolexicos-, this pretty bird frequents 
the banks of rivers, and finds its food in the sand ; it is seen either singly or in small flocks, and 
its shrill whistle may frequently be heard at night. It arrives about the beginning of April, 
and leaves about the end of September. 
The winter birds are now beginning to arrive so that in this month may be seen at the same 
time, the Swallow, which may be called the emblem of summer, and the Fieldfare, which 
may be considered as tliat of winter. Woodcocks, Scolopax rusticola, make their appear, 
mice; also several species of Wild-geese and Ducks. The CtosshiW, Loxia curvirostra-, 
remarkable for its bright colours, (red and bright yellow,) and for the singular structure of 
its bill is occasionally seen at the end of this month, or beginning of October, in flocks, feed¬ 
ing upon the berries of the Quicken, Sorbus auevparia, and other seeds and fruits. 
The young Redbreasts now attain their full colour. 
METEOROLOGY. 
The temperature of the atmosphere is much reduced, though there is frequently some beau¬ 
tiful weather this month. Equinoctial gales and storms may be expected about the end, and 
the changes in the Barometer are great and sudden.
