Godefiidus Guilielmus Leibnitius S. PD
on parum sibi debeo, quod cum discessa memoriam
noseri non dejosuisti, et ne ut presens multiplici
hamanitate devinxisti, ita absens inter anicos
numeras, quem ego sunc locun aliquo merisorum
genere lueri vel in posse, sed quando id sperare
vix ausim, sattem prontissima volantare ut-
cunque implere conabor.
De Cartetranis habes sententiam neam a
tua non abhorrentem, parum ab ipsis prestari
hodie, dignum Magistri ingenio coeprisq
Et vie quicquam ab illis inventum nom ines dignum
mendratu, usque adeo fatale et torpore occustarri
animos autoritati mancipatos. Ne in
Geometricis gaidem uno fluddenio demo
quicquam praestitere Cartesiani, Nam flugeni-
un ego inter Carlesianos ninine numero.
Unde intelligas vel Corlesium non publicasse
suas artes vel à discipulis non fuisse in
felleclas. = nanguam lipse Cartesins in Geone-
triam illam subliniorem non sasis penetrave-
rit. Unde fassus est alicabi in sua potestate
non esse problemata, ubi en proprietate tangen-
linea

taelias in censura sua quanquam interdum
paulo avrins multa tanen in Certesianos rerre
dixit. Iaq relim aliquem ex primipilis in Ba
tavis Galllaque respondere Ivio docrissino et
Magistri doctrinam et eriffinationem nultis
modis laborantem vindicare. od encertare
