 ''illustrandum. Evincet illud, Fel à Jecore & Vesicula ad intestina fluere; non é converso: nec à Vesicula & Jecore in Cavam, spectatâ momentorum diversitate, qua moventur jiuida per contractiles & inæqualis amplitudinis tubulos. Unde constabit, Bilem è Vesicula elici non posse, nisi extrinseca aliqua virtute comprimatur, quam ab adstante & distento cibis Ventriculo petam; statuens, Bilem in Vesicula ad digestionis tempus servari; ac tanium non evidenter ostendens, per ipsam, tum temporis ad Duodenum fluentem, cibum à Ventriculo prœparatum in Chylum facessere. Hine ratio sitûs Vesiculæ, Capsulæ communis in Jecore; cur item ductuum Felleorum aliquot in Vesicula desinant; cur non-nulla Animalia câdem desitituta sint, facile ex præcedentibus explicatur. Adhuc tamen observandus mihi situs Vesiculæ in quotquot occurant Animalibus, præcipuè Carneo ventriculo præditis. Pancreatis etiam locum pensito, & humorem illius exprimi eodem, quo Bilis, tempore, deduco, ut ab utrisque permistis Chylus formetur.''

Erit hîc, Appendicis loco, Geometricum quiddam, demonstrans, Qui sieri possit, ut in Vesica Urinaria qenerentur Conchylia spiralia, si per Ureteres exprimatur quid molle aut viscidum, in Vesicæ resistentiam incidens, eaque occasione explicabitur, quo pacto in supersicie Terræ similia intorta corpora possint produci, qualia in quibusdam montibus observavi.
