A Short Explanation of the TABLES. 
d The lower part of the common excretory 
bag like an inverted funnel. 
e The upper part of the faid bag, narrower. 
S f Two oval hollow parts, united to the 
excretory bag. . 
gg Two confiderable prominencies or papille, 
adhering to the loofe mufcular part of the 
abdomen. Thefe prominences fill up, while 
the creature lives, the hollow parts juft now 
mentioned. 
bb Two oblong and ftraight mufcles, which 
ferve to move the acetabula, that are, as it 
were, fupported by them towards the pa- 
pille, and draw them back again. 
zz The gills; and their blood-veffels, fituated 
at each fide of the abdomen, and at a great 
‘diftance afunder. 
& Divifions of the blood-veffels in the lamella, 
or plates of the gills, extended on the infide 
to their roots. 
11 The place where the lamellz of the gills 
terminate in a ligament, which ligament 
might very eafily be taken for a blood-veffel. 
m The fame more diftinétly exhibited ; as like- 
wife a view of the divifions of the blood- 
veflels in the lamellz of the gills. 
2 A tranfparent part, called mutzs. 
o The extremity of the ftraight gut, which 
floats in the abdomen, like a hollow tube. 
p The tranfparent ink--bag,. which likewife 
difcharges itfelf into the abdomen. 
gq Ywo tubular apertures, or openings, be- 
neath the ftraight gut, and near it, by which 
the feminal matter is emitted. 
r The place where there lie deeper, under 
the other parts, the veffels in which the fe- 
minal matter is prepared. 
s The tranfparent ftomach. 
¢ Atranfparent particle, in form of a heart, 
belonging to the {permatic parts. 
wz The extremity of the vafa differentia of the 
tefticle, floating likewife freely in the ab- 
domen, 
x The tranfparent tefticle. 
y Some arteries, which run to the mufular 
parts of the fkin. heir fellows are to be 
_ feen on the other fide of the body. 
z Tranfparent nerves, which appear in great 
numbers through the fkin, both there, and 
and at the other fide. 
a The mutcular circle of the mouth. 
e8 The arms, - cut off. 
yy The order obferved by the acetabula during 
the contraction of the mufcles. 
*5 The internal conftruétion of the broadeft 
and largeft of the eight legs. 
ee The two eyes. 
Bo Giidle: 
A very diftind view of the mufcles of the fmalleft 
acetabula, in their natural fituation and fize, 
as they appear on the extremity of one of the 
arms, feparated from the reft. 
a The conftruction and fituation of the mufcles 
of the acetabula. 
Ixy 
6 The mantier in which the acetabula are uni- 
ted with their mufcles. : 
cd The place where the mufcles are fhorteft 
and fmalleft, being where the rows of aceéta- 
bula begin and terminate. 
F IG. HL and IV. 
The body, called mutis, a iittle lefs than nature. 
aa Its upper part, which is very thick, and 
may be divided on each fide into two lobes. | 
6 Its obtufe appendages, in which the lower 
part of it terminates. 
c¢ ‘Two arteries, iffuing from the great artery, 
and running to cr fupplying the right and 
left fides of the mutis. 
d A membrane feparated, and turned back 
from the mutis, in order to give a view of 
it internal veffels. 
e The courfe of the veffels, exhibited apart. 
Ff A granulated fubftance, of which the mutis 
is principally compofed. 
BedeGar Ve 
The gullet, flomach, flraight gut, pancreas, and 
excretory duct of the Ink. 
a The jaws, 
6 b Salival glands, in their natural fituation, 
The gullet runs lightly over thefe glands, in 
its way from the jaws to the ftomach. 
¢ The ftomach. | 
d The blood-veffels of the ftomach. 
e The ftraight gut. 
J The pancreas, beautifully wound into a {pi- 
ral form. 
g& The bladder, ferving to force out the ink, 
6 The duct of the ink fromi the faid organ to 
the extremity of the ftraight gut. 
z ‘Th blood-veflels of the ink-bladder or bag. 
kkk & glandulous body, whofe ufe is not yet 
difcovered. 
Pra Gist VI, 
AA piece of the Cuttle-Fifh's bone. 
a A great number of little lamelle or plates; 
compofing the bone. The uppermoft are 
the largeft, and lie clofeft to each other. — 
6 'The hard crufty covering of this bone. ‘The 
lamelle or plates that are neareft to this cruft 
are the fhorteft, and likewife at the gceateft 
diftance afunder, {o as to afford a more fatis- 
factory view of the little columns that fup- 
port them, one above another. 
Bl Goa V de 
A microfeopical view of two of the lamelle, or 
plates, and their tnterjacent columns. 
¢ The beautiful order in which the colamns
