The two dilatations of the in:eftines, which I 
have juft now taken notice of, fupply the place 
of a colon, which appears only in the Caterpillar ; 
for in the Butterfly it is fo transformed, as de- 
fervedly to be confidered asa different part. Cer- 
tainly the furprifing and incomprehcnfible changes 
of parts which we here obferve, fhould engage 
our utmoft attention, though for many reafons, 
yet for none fo much as for this, that they moft 
evidently demontftrate to the whole univerfe, the 
excellency of the Great Creator. The contem- 
plation of thefe wonders has often led me to con- 
fider, whether the entrails of Nebuchadnezzar, 
when deprived of his reafon, and armed with 
talons, like a bird of prey, covered with hair, 
fuch as is found upon beafts, and condemned to 
eat grafs in common with the cattle of the field, 
did not fuffer 2 change in his internal parts, cor- 
refpondent to that which appeared in his external 
form ; and fuch a change as might {uit them to 
digeft the food, with which his life was to be 
{upported, in the courfe of this his moft examplary 
penance. At leaft there appears an occafional 
alteration of this kind in the entrails of thefe in- 
feéts ; for, as long as they continue under the 
form of Caterpillars, and live upon a grofs and 
earthy food, their entrails are alfo grofs and ear- 
thy; whereas thefe creatures, affuming a more 
delicate form, and beginning to fubfift on a more 
pure fubftance, the organs by which fuch fub- 
{tance is to be taken in, digefted, and diftributed 
to the feveral parts of the body, become like- 
wife more delicate, and that indeed to fuch a de- 
eree, that the alteration would never be credited, 
if the eye did not trace its gradations from one 
day to another. 
There is no part of the Butterfly that deferves 
our admiration more than the trunk *. I have 
but rudely delineated this organ, becaufe I pro- . 
pofed making many other figures of it, confider- 
ably bigger than the life, which, after all my pains, 
‘J have not been able yet to perform, on account 
of the badnefs of the weather, and the feafon’s 
being now fo confiderably advanced. ‘That extre- 
mity of it, with which the Butterfly fucks in its 
SPINGEL! Ue Roa enter 
food, is particularly curious in its conftruction : 
it confifts of a double tube, divided, as it appears, 
into many articulations. This conftrudtion fuits i¢ 
to a great variety of motions, and in particular, 
makes it eafy to ftretch ont, and curl up again. 
It appears, that when the Eutterfly fips up the 
honey or liquid {ugar upon which it lives, a por- 
tion of air mixes with and accompanies this 
through the trunk to the ftomach. This may 
. be feen by faftening the Butterfly by its wings, 
with a very fine pair of iron pincers, and uncur!- 
ing the trunk with a very fine needle, fo as to 
bring the tip of it to bear upon a blade of erafs 
dipped in fugar water; for the Butterfly immedi- 
ately fucks the nourifhment that is thus offered ; 
and, with the affiftance of a microfcope, both that 
and the air that goes along with it may be traced 
in their courfe into the body: and this isa very 
entertaining fight. Indeed Butterflies may be 
kept alive in this manner many days together: 
they will take fo well to this way of feeding, that 
at lait they will dart out of themfelves, with- 
out any compulfion, their trunk into the moift- 
ened fugar, or honey water, thus offered them. 
Hence we may guefs how fine and delicate the 
mufcles, veins, arteries, and nerves muft be, by 
which this little organ is fupported and governed. 
The very extremity of itis of amoftamazing ftruc- 
ture. As formy part, I muft ingenuoufly own, 
that neither my eyes, my hands, or my head, are 
equal to the task of infpecting, handling, or per- 
fectly defcribing it: but even this weaknels is an 
ufeful leffon, fince I learn by it, that all our 
boafted knowledge and perfection in this life, is 
in the main but ignorance and mifery. Let it 
therefore fuffice, that the things we fee, are cap- 
able of conduéting us, as it were, by the hand, 
to the knowledge of a much fublimer being ; 
and let this confideration engage us, to adore the 
Divine Majefty, according to the perfect rules 
he himfelf has been gracioufly pleafed to pre- 
fcribe to us, and to perform, with due reverence, 
the penance enjoined us for tranfgrefling his 
commands. This isthe one thing neceflary ; all 
elfe is vanity of vanities, arid altogether unwor- 
thy of our attention. 
The genital organs of the male Butterfly. 
O N diffe@ting a male Butterfly of this {pecies, 
four days after its laft change, the genitals 
appear perfect in every refpect. The penis, 
‘Tab. XXXVI. Fig. 11. 2, placed near the ex- 
treme rings of the body, has on each fide two 
horny little bones, 44, of a pale brown colour, 
which cover it behind and in the middle. ‘Thefe 
little particles have an articulation, with a bor-

der, c, of the fame fubftance, which furrounds 
the penis like a belt. There is near the two 
little horny parts, already taken notice of, another 
that is hooked, dd, and behind, is divided in 
two; by the parts of the penis, ¢. On raifing the 
two firft little horny bones, there appear two 
crooked litcle claws, whofe bufinefs it is to 
erapple, and firmly hold, during the act of co. 
be expected, but itreally is of the nature of amouth ; for all the food goes through it. ‘The fubftance of the trunk is horny : the 
creature may be faid to unroll it, 
by {queezing the head; or it may be drawn out with a pin. After this, if any violence be ufed to 
the creature, the trunk will crack lengthways in the middle, and the flit will run prefently through its whole length, and divide it 
into two. Bonani hence fuppofed the trunk was really double in the Butterfly, or originally compofed of two. Riget thought 
he had fhewn, from unqueftionable experiment, tha 
olence offered to it, and its own tender flructure. 
t the trunk of this infeét was fingle, and that this fplitting was the effect of the vi- 
He had his followers, till Reaumer verified the firlt doctrine of Bonani by more 
accurate trials; and eftablithed the true flructure of this part, which is, that it is compofed of two delicate tubes, laid parallel by one 
eanother.
