Again, If this were true, and that the Bever in chase makes some divulsion of parts, as that which we call _Castoreum_; yet are not the same to be termed Testicles or Stones; for these Cods or Follicles are found in both Sexes, though somewhat more protuberant in the Male. There is hereto no derivation of the seminal parts, nor any passage from hence, unto the Vessels of Ejaculation: some perforations onely in the part it self, through which the humour included doth exudate: as may be observed in such as are fresh, and not much dried with age. And lastly, The Testicles properly so called, are of a lesser magnitude, and seated inwardly upon the loins: and therefore it were not only a fruitless attempt, but impossible act, to Eunuchate or castrate themselves: and might be an hazardous practice of Art, if at all attempted by others. Now all this is confirmed from the experimental Testimony of five very memorable Authors: _Bellonius_, _Gesnerus_, _Amatus_, _Rondeletius_, and _Mathiolus_: who receiving the hint hereof from _Rondeletius_ in the Anatomy of two Bevers, did find all true that had been delivered by him, whose words are these in his learned Book _De Piscibus_: _Fibri in inguinibus geminos tumores habent, utrinque vnicum, ovi Auscrini magnitudine, inter hos est mentula in maribus, in fæminis pudendum, hi tumores testes non sunt, sed folliculi membrana contecti, in quorum medio sunguli sunt meatus è quibus exudat liquor pinguis et cerosus, quem ipse Castor sæpe admoto ore lambit et exugit, postea veluti oleo, corporis partes oblinit: Hos tumores testes non esse hinc maxime colligitur, quod ab illus nulla est ad mentulam via neque ductus quo humor in mentulæ meatum derivitur, et foras emittatur; præterea quod testes intus reperiuntur, eosdem tumores Moscho animali inesse puto, è quibus odoratum illud plus emanat._ Then which words there can be no plainer, nor more evidently discovering the impropriety of this appellation. That which is included in the cod or visible bag about the groin, being not the Testicle, or any spermatical part; but rather a collection of some superfluous matter deflowing from the body, especially the parts of nutrition as unto their proper emunctories; and as it doth in Musk and Civet Cats, though in a different and offensive odour; proceeding partly from its food, that being especially Fish; whereof this humour may be a garous excretion and olidous separation.
