The “BeOMO! Roof 
parts, by the air which is impelled inwards, 
for at that time they are all inflated with wind. 
The inverfion of thefe parts is performed in 
this manner; the extreme and hairy part, Tab. 
XXI. fig. 111. 7. of the pudendum is firft 
forced out by the Bee, and then the horny g 4 
extremity of the fame pudendum is likewife 
advanced out from the laft rings of the body, 
-and at the fame time the root of the penis ee, 
together with the faid horny part / contained 
in it, ftarts or is thrown forward, and the vafa 
deferentia c c, and feminal veficles d d, are like- 
wife drawn fomewhat towards the fore parts. 
Afterwards the four diftingt little parts begin to 
{well and throw themfelves out of the body ; 
that is, the two pointed appendages & 4, the 
pyramidal particles z, and the fine ringed little 
part. Before thefe four parts are erected and 
thruft forth, one may fee in what manner they 
{well forwards through four diftiné little cavi- 
ties, {uch as are feen in the fingers of a glove, 
when you haye juft begun to invert them. 
And further, one of the clofed appendages, as 
alfo,, the little part with its fine rings are feen 
through the skin. 
The appendages, as Ihave already obferved, 
are firft inverted, and their bafis is then turned 
out, Tab. XXI. fig. 1v.//, when we fee their 
clofed extremities {till lying between them and 
not yet inverted. But the pyramidal little part 
alfoz is then unfolded more and more upwards, 
as well as the fine ringed little organ4; the 
horny part alfo fituated at the root of the pe- 
nis f is then propelled or pufhed further for- 
wards, and is fixed higher in the horny little 
part of the pudendum qg q; but the hairy part 
of this is no way changed in its fituation. 
220 
Then the appendages being by degrees en- 
tirely inverted, appear diftended and {wollen, 
Tab. XXII. fig. 1.24, at which time the root 
of the penis e, together with its interior little 
horny part f; are moved yet farther outwards, 
and this begins to penetrate fomewhat deeper 
into the cavity g g of the horny or bony part 
of the pudendum: the pyramidal little part z 
alfo is now turned further out, and the little 
part with fine rings 4, which is then partly in- 
verted now appears to the eye: however, the 
fhagey part 7 of the pudendum as yet fuffers 
no change. 
But at this very time the pyramidal little part 
fig. 11. 2 is at length all turned out and ex- 
panded, and the other little part likewife fhews 
itfelf: it has five divifions, and fhort briftly 
hairs; and it now appears very elegantiy and 
beautifully bent 6. ‘This makes the more agree- 
able fight, as thefe five divifions are of a bright 
red colour, but the reft of this little part is 
membranaceous and whitifh. The clofed ap- 
pendages & & retain their figure, and only the 
horny little part fituated in the root of the pe- 
nis, is by degrees more and more thruft out, 
and is further introduced into the horny part of 
the genitals. Hence it happens that the root 
of the penis e becomes ftraighter, whilft the 
NA TURE; ot, 
fhagey part r of the pudendum {till remains a8 
It was. 
If one continues to prefs out thefe parts fur. 
ther, the skin being the pyramidal little part, 
and that which ‘has five divifions, is by degrees > 
widened and diftended ; and hence it after- 
wards happens, that what is called the penis, 
fig. 111. g, appears there in this manner ; it 
turns itfelf entirely out, exhibiting a membrana- 
ceous ftructure, and beautiful corrugations in the 
head ¢. ‘Then the pyramidal particle 7 like- 
wife becomes entirely unfolded and expanded ; 
and the horny little part;f enclofed in the root 
of the penis, is entirely, with a great part of 
the root itfelf, preffed out of the body. This 
is forced through the ‘middle of the horny, 
Tab. XXII. fig. 111. gg, and hairy r r_ part 
of the genitals: hence the little part with fine 
rings is then likewife dilated and extended fo 
far, that on each fide it appears wholly reclined 
towards the hairy part rr of the pudendum. — 
As thefe parts are pellucid, the horny little 
part f is feen through the skin of the penis, 
whilft in the mean time the little part with 
fine rings being plainly drawn down under it, 
refembles as it were an expanded membrane, 
and appears marked with fome lines or bright 
red grooves or furrows, between which are {een 
its five divifions. I do not think it neceflary to 
delineate all and each of thefe : but the clofed 
appendages ££ are then, without any regard to 
thefe feveral changes, obferved to remain in 
their former figure and fituation. 
Whilft thefe parts are in this ftate below the 
penis as it is called g, is feen a confiderable 
aperture #, which appears underneath and be- . 
tween the divifions of the horny little part fi- 
tuated inwardly at the root of the penis; 
through this aperture, not only the faid little - 
organ but a great part of the root of the pe- 
nis may be forced, and thus will caufe the 
{perm to flow plentifully from thence. The be- 
fore defcribed cavity of the genitals feems from 
hence, therefore, to be the true paflagew of 
the fperm, though for fome time I have attri- 
buted that office to what is called the penis g ¢; 
but I obferve that this as well as the other parts 
is clofed and has no orifice. Wherefore I can- 
not imagine what ufe this little part is of; as 
I do not yet conceive the purpofe of that other 
little part, which one may take for a penis. 
On the contrary, I think I very clearly fee that 
the internal horny particle f is made in order. 
to dilate the root of the penis with its ftiff- 
nefs, and to preferve it when opened, by which 
an eafy paflage is given to the femen through 
the latter. Indeed, in my opinion there was 
a neceflity for fuch a caution, on account of 
the great impetus wherewith thefe parts are 
forced out; for if that little part were not hard 
as horn, the faid paffage would be eafily {queez- 
ed together, and confequently the ejection of 
the feed hindered. But whether thefe particles 
which are inflated with air, contribute to pro- 
pel the reft of the parts out of the body, and 
whether
