66 The 
“part, they are connected in the middle, with 
two other horny, and very fingular bones, d, 
which ferve to keep them in their places, and at 
a proper diftance from each other. . 
The gullet, which lies between thefe appen- 
dages of thofe little bones I have been defcribing, 
and in their hollow part, becomes confiderably 
wider in the Worm’s thorax, e, where it, ina 
manner, forms an ingluvies or large hollow. 
Under this are-feen four appendages, clofed at 
their ends, ff, which are, as it were, cluftered 
about and furrounded by little globular particles 
of a fatty matter, but of a peculiar nature. They 
are indeed properly made up of thefe. As yet I 
cannot determine what thefe particles fhould be 
called, or the ufe of them may be, unlefs, per- 
haps, they may ferve to moiften the food of the 
Worm, in its paflage through the cefophagus or 
eullet, and thereby render it of eafy digeftion. 
The ftomach, ggg, offers itfelf next to our 
confideration. It is very long, as is the cafe in 
all other infects, while they continue in the 
Worm or Caterpillar Mate. It is fupplied with 
a great number of ramifications from the wind- 
pipe ; but I have omitted them all in the figure, 
‘except two principal, and fome other {maller, ra- 
mifications diftribured over the furface, bb. 
The length of this ftomach is fo very confider- 
able, that one might eafily miftake it for a gut, 
and defcribe it as fach; and no doubt, I fhould 
have been myfelf of that opinion, had I not had 
an opportunity of comparing together the con- 
ftruétion of this, and of the ftomachs of other 
infe@s. This ftomach is of a membranaceous 
fubfance, in which there appear fome mufcular 
fibres through its tranfparent coats. All the con- 
tents of the ffomach were white: I have en- 
deavoured to reprefent them in the figure by fome 
dots, as feen through the coats of the ftomach, z. - 
The ftomach appeared alfo invefted with nume- 
rous particles of fat; but I did not difcover this 
lat circumfance in the ftomach, till after I had 
. dried it on a thin piece of glafs. 
Lower down, towards the end of this chan- 
nel, there rife from it two little flender inteflines, 
2k, like thofe found in all other Worms or Ca- 
terpillars, that 1 have yet diflected, and even in 
the Loufe. Icall thefe caca, or blind inteftines, 
In the Mite, thefe two inteftines divided, each 
into two others; two of thefe contained a greenifh 
yellow fabftance, J]; and the two others, a mat- 
ter that was partly green, and partly white, and 
looked as if it was coagulated, mm; but what 
was very furprifing, the motion of this fubftance 
through the inteftines was fo quick, that my 
eyes could not keep up with it; and, on my cut- 
ting one of the inteftines in two, It flowed from 
it with great rapidity. ‘This I obferved in a live 
Worm, that I diffected ; but in another, which 
began to putrify, 1 found the coat of this intef- 
tine difolved into an infinite number of little 
fatty lumps. In both, thefe inteftines were of a 
prodigious fmaline& ; but from the motions of 
the matter contained in them, we may reafon- 
ably conclude they are furnithed with mufcular 
fibres, though I could by no means obtain a 
fight of them, as they evade by their extreme 
BOOK of NATURE; 
Gr, 
delicacy, the fharprefs of both our eyes and in- 
ftruments, which are at beft only fit to examine 
vifible and fenfible objects, and even thefe very 
imperfectly, How much therefore are we bound 
to humiliate our hearts, when, on account of 
out great weaknefs, we cannot thoroughly fearch 
into any one of God’s creatures! Thefe intef- 
tines had alfo their pulmonary tubes, 7, And’ 
who can tell how many more wonders may yet 
remain hid in them! 
The pylorus, 0, or opening of the ftomach, 
appears below the infertion of the four inteftines 
I have been juft defcribing, and near to this is 
the gut colon, ~~, which is followed by the 
rectum, g. I could difcern the very extremity 
of the rectum, 7: it was of a fomewhat diffe. 
rent form from that which I have given it in the 
figure ; for I there reprefented it as it appeared 
on my fqueezing it at the fundament out of the 
Mite’s body. 
It is extremely remarkable alfo, that two of 
the ceca or blind guts, were fo united with par- 
ticles of fat, ss, that their clofed extremities ap. 
peared firmly fixed in them, and connected with 
therm by means of a great number of pulmonary 
tubes, Inthe figure I have only reprefented this 
circumftance in one of the inteftines. There are 
inthis creature a great number of thefe particles of 
fat. ‘They are of an oblong oval form, fometimes 
double, and fometimes hung about with appen- 
dages, round, hollowifh, and flat, as may be feen 
in the two little portions of this fat, which I 
have here reprefented, ss. 
On examining this fat with a powerful magni- 
fier, every divifion or lobe of it appears wrapped 
up in its own particular membrane. We may, 
even by this means perceive, that every fingle par- 
ticle of this kind, contains an infinite number of 
globules of fat, Fig. vi. gaa, which flow out 
of the lobe as foon asit is opened, and mix con- 
fufedly together; fo that, a variety of branches, 
compofing, as it were, a little tree, are formed 
by the- combinations of the concurrent lobes. 
The particles of this fat are of a dufky white, and, 
by. this means, they exhibit in the Worm a 
{pectacle, whofe beauty no words can properly 
defcribe; but we need not think this extraordinary, 
as it is effected by the Omnipotent Being, who, 
with a word, produced all things. 
It is very entertaining alfo, to confider in what 
manner the pulmonary tubes, which are of a 
bright filver whitenefs, Fig. vi. 4, run every 
where, and in every poflible direction, through 
thefe pinguiferous or fat veflels, fo as to diftribute 
themfelves principally over the particles of the 
fat, where this fubftance is laid up in little round 
lumps; at the fame time, that in the interftices 
of thefe lumps, they run into one another with- 
out any apparent order. 
On one fide of the gullet, there lay a very 
delicate and {mall tube, ftretching to the jaws, 
and the horny bones conftituting the palate and 
mouth ; but I have not as yet been able to trace 
this tube perfectly to its origin. 1 found that it 
divided itfelf, in the breaft, into two {mall chan- 
nels, each of which widened again into an ob- 
long globular bladder, Fig. v. ¢7, and then be- 
came
