HAving spoke of the several Extreamities of the Capillaries, dispersed through the glands of the Liver, belonging to the Bladder of Gall, and the Choledoch Duct, as the Receptacles of Choler: It is orderly now to Treat somewhat of the Liquor it self Percolated, as secerned from the Vital Juice, which are Bilious Recrements, and by some are thought to be specifically different; but if they be well considered, * 1.1 they differ only in qualities, and not in kind, Magis & minus non variant speciem, and so are only several degrees of the same Specifick Matter; whose more gross parts are more easily transmitted through the larger Orifices of the Excretories, appertaining to the Porus Bilarius, while the more thin and sharp Particles of Bilious Matter, do more easily insinuate themselves into the more nar∣row Extreamities of the small Vessels, appendant to the Bladder of Gall, wherein it borroweth greater degrees of Acrimony proceeding from its long stagnancy, and as being mixed with Choler, long resident in the Cavity of the Bladder, and is associated with Choler newly severed in the Glands, (lodged between the Coats of the Bladder) and carried through the small Pores of the inward Coat, into the bosome of the Bladder of Gall.
And that the Bilious Recrement, relating to the Bladder of Gall, * 1.2 hath qualities differing from that of the Choledoch Duct, Renowned Malpi∣ghius, hath taken the pains to evidence by an Experiment, Lib. de Lien. Cap. 6. Dum scilicet in brutis ligata Arteria Hepatica prope Truncum Caeliacae lacerato{que} Bilis folliculo, vel etiam avulsis ejusdem tunicis, coercito{que} pancreatis vase, superstite per diem animalis Vita, per portam in Jecur irruente Sanguine, bilis ingens copin è Poro Bilario, & Choledocho in Duodenum transducta colli∣gitur, quae Colore nequaquam simili pollet, cum dilutior sit, nec tantum lentoris & amaritiei obtinet, quantum bilis passim Vesicae possidet; & si igne vel alio consimili exagitur, vehementissimum exhalat odorem, alia{que} longe diversa à Cy∣sticae bilis natura patitur.
Three sorts of Choler may be conceived to be in the Liver: * 1.3 The one is never severed from the Blood in the glands of the Liver, but is intimately
