De modo mensurandi pro fundita
tem abyssi et quomodo vulgo erresi
intempestioo usu regulae proportonum
Video insignes superiorum temporum
Mathematicos subinde gravissimos erro–
res commisisse, quod Progressionum
variarum doctrinam ignorarent,
sibique persuaderent tuto ubique posse
adhiberi regulam proportionum,
quam auream vocant Ita qualter
Revius qui Vitruvium Germanicum
dedit, et de Machinis pro suo tempor
satis belle scripsit. proposuit modum
inveniendi profunditatem abyssi vel
lacus ad cujus  fundum
jacta bolide pertingere non licet.
Si scilicet demittatur projiciatur in
aquam pondus cui adhaereat pila lignea
quae ubi pondus fundum attigit elateriolo
presso liberetur, Tefus et sua levitate
rursus emergat, tempus ab immersione
ad emersionem mesitur depsudra vel
clepsammio. Hactem non male, in eo
tam vult
voru malo qnad uult idem instrumentus
adhiberi in loco notae profunditatis
temporisque intervallum inter persionem
et emersionem iterum notari, ac
deinde fieri in regula aurea,
ut tempus ic seocente in loco nota
 profunditatee  ad notam
profunditatem ita tempus in loco
quaesitae profunditatis ad profun
ditatem quaesitam. Qui tamen
calculandi modus tum demum succedem
si corpus ascendens aut descendens 
motu uniformi moveretur, cum tamen
is sit acelleratus seu multo velocior
versus finem. itaque qui sic calculum
iniret, haud dubie a vero admodum
aberraret. Obiter hic noto, schven.
