Quarta ſiphonum ſpecies minus ſimplex eſt: nam conſtat ex duobus uel
tribus ſiphonibus: quorum pila attollit machina, quam uerſant homines:
etenim cuique pilo eſt dens, quem ſuculæ bini dentes uiciſſim tollunt.
Eam
duo uiri robuſti, uel quatuor, cogunt.
Sed cùm pila decidunt in fiſtulas, eo-
rum orbiculi hauriunt aquas: cùm attolluntur, eaſdem aquas exprimunt per
fiſtulas.
Cuiuſque aut pili ſuperior pars, quæ in foraminibus tignorum tranſ-
uerſariorum continetur, quadrangula eſt, & craſſa atque lata ſemipedem: reli
qua, quæ in fiſtulas incidit, & ex alio ligno facta eſt, tota teres.
Horum trium
ſiphonum quiſque ex duabus continentibus fiſtulis, ad tigna putei affixis, com
ponitur
.
Verùm hæc machina altius aquas haurit, utpote ad pedes quatuor
& uiginti.
Si foramina fiſtularum magna ſunt duo tantum modo ſiphones
fiunt: ſi paruæ, tres: ut utroque modo machina oneri par eſſe poſsit.
Idem de
cæteris machinis earumque fiſtulis ſentiendum eſt.
Quoniam uerò hi ſipho-
nes ex duabus fiſtulis conſtant, pyxis ferrea, ut etiam prius dixi, cui eſt foricu-
la ferrea, non includitur in trunco, ſed in qaeſtula inferiore: & quidem ea par
te, qua ad ſuperiorem adnectitur: atque ita pili pars teres ſuperioris tantum-
modo fiſtulæ longitudinem habet.
Sed hanc rem mox planius explicabo.
Pili dens A. Suculæ dentes B. Pili pars ſuperior quadran/
gula C. Eiuſdem pars inferior teres D. Tigna tranſuer-
ſaria E. Fistulæ F. Eius apertura G. Canalis H.
