uerſario, quòd fiſtula AC nil prorsùs ab incluſo mer-
curio BC grauatur, & ſic de facto experimur appli-
cata digiti pulpa ori infimo fiſtulæ; quod in partę
intermedia pulpæ à mercurio tacta nulla compreſſio,
nec contuſio neque grauitatio perſentitur, quando præ-
cisè mercurij altitudo BC eſt vnius cubiti, & qua-
drantis
ferè; quod ſieius altitudo ſupra CB augeatur,
tunc ſolummodò percipitur in medio pulpæ digiti ſub-
iecti compreſſio grauitans iuxtà menſuram exceſſus mer-
curij ſupra eum qui altitudinem vnius cubiti, & qua-

tur violentèr infra debitam altitudinem BC, tunc ne-
dùm ſubiecta pulpa digiti non comprimitur, ſed è
contrà exugitur, vt efficiunt cucurbitæ medicæ, &
hyrudines.
Sed dicet aduerſarius ſi mercurius BC
nil grauitat, nec comprimit digitum, quare requi-

Reſpondeo aereum cylindrum SA fiſtulæ vitreæ in-

CA non repellatur æquali actione contraria ſursùm
ab aere collaterali SG, quia huius vis exercetur, &
omninò expletur ſuſtentando mercurium BC; igitur
neceſſariò vitrum CA comprimitur deorsùm à gra-
