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.
So far this Inquisitive Anatomist, which the Publisher (who very much doubteth, whether any Copies of this intimation, Printed at Pisa this very year, besides that one, which lately came to his hands, be to be found in England) thought fit to insert in these Papers, thereby to administer occasion to our dextrous Anatomists here, with all possible diligence and care to pursue, joyntly with that Italian Professour, those important Inquiries about such considerable Subjects, as have been above related; comparing with their Researches in this matter the many notable Experiments, lately published in No 63. and 64. of these Tracts, made and communicated by the Honourable Robert Boyle.
