Recti ebere; quam Joh. Bernoullius ex Leibnitius atque IIugenius
funi laxe acue suxtu, vel catenula ab ambobus sui terminis pen-
denti conrenire docuerune, etsi corum analpsis relariae nusquam pu-
blici facta sic juris. Sed quanquam catenaria atque velaria una ca-
demque int curra, non tamen ideo putandum, unius inrestigatio-
nem simul alterius quoque inventionem includere, adco ut, qui ca-
tenariam geometrice invenerie, etiam relariae problema solutum de-
disse censendus sit, quod tamen Claris. Vir Darid Gregorius insi-

Quod si loco gravitatis alia quaelibet vis similiter acens in lineam fexi-
lem vires (uas exerat, eadem producetur linea V. e. Si ventus aequabi-
lis supponatur, e secundum rectas datae positione rectae parallelas spi
rans, linea vento instata eadem erit cum catenaria. L’atcor quidem In
theli, ut ajunt, veram esse Poresii Viri assertionem, cequis enim
ambiset, quin alia quae cunque ris, loco graritatis substituta, simili-
ter applicata, ac eodem prorsus ac sraricas modo asens, cundem
