In fixing ButtprHit-s, Moths, ike. in the cabinet, after they 
liave been fastened down, by means of a pin rnn throii^li tlie 
t';orax, the wings on one side should be expanded, and a nar- 
row strip of card laid over them, which should be fastened 
down at both ends by pins, so as to retain the wings in their 
position, the other side must then be tieate<i in the same way 
(fig'. IG) the lej:s and antennae must theji be plaoedproperly, and 
the insect left for a few days to dry, wlien tlie cards may be re- 
moved, and the wings will afterwards remain as they were 
fixed. In these operations, a small needle and hook, (fig. 17) 
ecured iu wood handles, will be useful.

In the larger Moths, it will be necps«ary to remove the viscera, by means of the liook, and 
to till up tlie l)ody with cotton-wool muiatened Wlih the following mixture: — 
Corrosive Sublimate, . . '. 1 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 /'/(»«s/«r, and Acartis destructor, 
which would soon destroy a whole collection. 
The caterpillars of the Death's-Head Hav.'k-Moth, Acherontia atropos, may be found occa- 
sionally, feeding on the potato, at night, tliough they ai'e concealed in the day, beneath the 
under leaves or in the soil. They are remarkable for theirsize, being sometimes found five inches 
long, and are furnished with horns and tail. They should be placed in a flower-pot filled with 
moiild, and covered with gauze-net, as they imdergo their transformation in the earth. 
The Painted-Lady Butterfly, Vanessa cardui; and the Red Admirable, f. alalonta; may 
frequently be seen on decaying fruit on walls. The Copper Butterfly, Lycoena phlmns; the 
Brimstone Butterfly, Goni'pteryx r/iamni; the Saflfron Butterfly, Colias hyale; and some other 
kinds may also still be occ;isionally met with. 
The webs of the Go.';samer Spider, Aranea ohtcctri.v, the manner of jiroducing whicli, has 
been the subject of so much curious disquisition, and controversy may now be seen, particu- 
larly oil a fine niorninj^, afier a fog, covering the 'jelds, hedges," bushes, and pathways, in all 
directions, and appearing like string's of small pearls. 
ORNITHOLOGY. 
Most of the summer birds of passage now leave ns, as the Wryneck, Vunx torquilla ; the 
Red-start. Sylrii/ I'/i/riiiciirus; the Blackcap, Sylvia ntricapill'i ; the White-throat, Syhna 
cinerea; Winchat Sylnii rvlietra; the Swallow, Hiru;ido\TUSlica; the Spotted Flycatcher, 
Mvscicupa ;/rhohi; and the Common Sandpiper, Trinija hypoleucos ; this prettj' bird frequents 
the banks oif 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 that of v/inter. \Voodcocks, Scolopax rustlcola, make their appear, 
ance; also several species of Wild-geese and Ducks. The Crossbill, /.o.r/« CL/rjJi'ro.s/ia; 
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 ciucvparia., and other seeds and fruits. 
The yoiinj; 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 expect.,'d about the end, and 
the clianges in the Barometer are great and sudden.

perfection. The mean point of the Thermometer, li.is been about 73 Fahrenheit, Highest 86.
