TJylenbroek, Pieter Johann. Responsio ad quses- 

 tionem hydrostaticam : " Ponitur vas cavum ex 

 materia densiori quam aqua confectum, a latere 

 foramine instructum, aqua penitus impletum, 

 eidemque prorsus immersum ; hujus igitur vasis 

 parietes interni quaeritur utrum aliam pressionem 

 patiantur, si foramen sit clausum ? aliam si sit 

 apertum ? Postulatur, ut responsio sit legibus 

 hydrostaticis innixa, quae simul exhibeat rationes, 

 modos et discrimina, quibus lis inter doctos 

 saepius agitata penitus dirimi possit, an fluida 

 gravitent in propriis locis ? " Leijden, Annal.
