43. A doubt can be raised:

What is liquified by heat is not solidified or coagulated by it; ductibles are liquified by heat, therefore they are not coagulated by it.

Again, it was previously established that things that start coagulation with heat and end with cold are insoluble. So since ductibles are liquifiable their coagulation may not begin with heat and end with cold.

In reply to the first argument we should say that ductibles are as much coagulated by cold as they are liquified [by heat], and they are only liquified until coagulation by heat ceases and not after [heat is withdrawn].

original latin

Ad aliud quod quorum coagulatio incipit a calido valde consumante humidum et terminatur a frigido consumante quod relictum fuit a calido illiquabilia sunt. Sed calidum quod fecit quandam coagulationem in ductibili -- scilicet, in principio suae generationis -- congregavit enim vaporem unde fit ductile, non consumebat valde humidum illius vaporis, et ideo bene potest liquari. Propter tamen multa verba in hoc capitulo dicta, dicunt multi quod Aristoteles non fecit hoc tractatum, sed est additus vel editus ab Avicenna.

45. Dubitatur:

Terra quae maxime sicca est quiescit in superfice plana, siccitas ergo in vivo argento non erit causa quare non quiescat in superficie plana.

Dicendum quod siccitas in vivo argento est valde subtilis, et ideo non terminat aqueitatem vivi argenti in tantum ut possit quiescere in superficie plana.

44. Dubitatur:

Vinum non est ductile ut ductile prius definitum est.

Dicendum quod communius hic sumitur quam prius; dicitur enim hic ductile quod qualidam * conglutinationem habet in humido.

Remarks on vocabulary : This passage contains a word that seems not to be found in any dictionary `qualidam'. Clearly it is an adjective that means: of a certain kind. It has been formed on the model of the indefinite pronoun: quidam, quaedam, quiddam, but it has a different stem: qualis, quale, meaning 'a sort of, a kind of.' Why the accusative is written `qualidam' rather than `qualendam' is a mystery, at least for now.
