ionis, quia cum solaris calor in pu- dum, ecc. cur aurem inaius lumen
eis Padiis diffundatur, facile illi
permeane lapidem, ex parre dia-
Phanum; ac vero calor, qui a nO-
itroione diftunditur, cum mulco
haliru commiscetur, qui certe la-
pidem Tubire non porest; igitur
minorem effectum praectac noster
ionis; aliquem camen praestat, mo-
dico illo calore puro, quem per
medium diffundie: hac eadem 1a-
tione iam Cupra probaui, calorem
rectactum à nolrare ione diitu-
Cum, valde remiltum (ve aiune) ee
debilem elle.
9. Licec lapis noster in pyxi-
dula claula mulcum incalelcat a
proximo igne, nullam camen lu-
cem pexide aperra praetere, ratio
est, quia puri cancum calorisra-
diis accenditur, qui opacam pexi-
dem Cubire non poltunc, cur aucem
puro lumine accendatur, racio cAt,
quia radii Cubire debene, de quali
Denecrare iplum lapidem, ve sub-
eilem illam mareriam, mulcumque
praepacacam in incimis poris de
apochecis lapidis accingane, et ac-
Cendant.
10. Hlinc noster lapis ex ParTC
perspicuus est, acque diaphanus;
racio parer ex dictis, nili enim ex
Parre diaphanus essee, radii puri
caloris Cubire; ac permeare nOI
Pollene; igieur nec materiam in
incimis cauicatibus lacentem ac-
cendere.
11. In oblcuro cantum concla.
ui praedictam lucem aspicimus;
quia cum lux illa sic debilissima,
a maiori lumine quasi extinguieurs
hoc iplum etiam accidic iis cor-
poribus qua noctu cancum lucene,
minus oblcurec, rario est, quia
maior aftectio oculi, minorem
complecticur, e delet, ve fgu-
Fa, houram, Ced de hoc infra.
12. Calcinatur praedictus lapis
de non Lemel calcinatio repecituE;
racio est, quia per calcinacionem
leparatur crassior humoris porcio,
acque adeo maceria minus ini am-
mabilis; induranturque cerrestres.
ac Colida parres, porolque de apo-
checas relinguune, quae cum va-
cux non line; illam inaceriam in-
Aammabilem, mulcumque detaca-
tam continene; nec enim puces la-

Pradictus lapis calcinetur.
13. Vbi quis evigilac, maiorem
