Dugs ; and as they found a Penis and f eft ides in 
the fame Animal, they were ready to conclude it to 
be an Hermophrodite : But on differing the Fe- 
male, they found a Uterus , with two Horns like 
that of Pitches, befides the Receptacles of the Ca- 
Jtor, which I fhould have thought fufficient to have 
fet our Anatomift to rights, as to the former Bea- 
ver's being an Hermophi odite. 
Johannes Francus, a German Phyfician, hath 
publifhed a Treatife called, Caftorologia explicates 
Cajioris animalis naturam & ufum Medico-che • 
mount % Augufi. Findel, 1685, dvo^ being a Com- 
mentary on a Treatife formerly wrote by one Johan . 
Marius , a Phyfician at Ulm. 
Marius, in Sed. VII, defcribes the Receptacles 
of the Cajtor, as being Bags near as big as a Goofe- 
Egg ; and that they have been wrongly called the 
Dejicles, being in Females as well as Males, but that 
they have no Communication with the Pudenda - 
His Commentator Francus recites the Opinions of 
fome modern Writers, who are ftill in the old Error 
as ancient as ALlian, who fays, that the Beaver 
bites out his own Fejlicles , when purfued by the 
Hunters, as if he were confcious thofe were the Parts 
his Perfecutors want, and feek his Life for. He 
cites Adam Zvoikerus as having this Notion, and 
likewife Job. Harderus and Job. Schapplerus ; 
nay, fome have thought fo abfurdly, as to imagine 
that the Beaver had four Dejticles : And he fays, 
that Gulielmus Rondeletius was the firft Perfon who 
diife&ed a Beaver with Accuracy fufficient to refute 
{he old Error ; fhewing that the Cajtor was not the 
Jejl teles, but peculiar Bags lying in the Groin.
