Annotatio I §.III GENERICA nearer: Signatum de signo — metonymy/synecdoche when sign ≠ thing; sacramental induction
(II) As nearer genus, the GENERIC view shows the sacramental proposition predicating the thing signified of the sign.
That can be proper only when sign and thing are materially the same; when they differ, the predication is metonymic or synechdochic — sign for thing, container for content, or part for whole — and so improper.
Induction from Old and New Testament sacramentals in the Supper’s own Institution confirms that a horistic sacramental proposition is improper by nature.

(II) GENERICA quà genus propius, exhibet propositionem sacramentalem, in qua signatum de signo praedicatur. Etsi verò sic praedicatio propria esse possit, quando nim. Signum cum signato materialiter idem est, tamen non potest non esse impropria, quandocunque signum & signatum materialiter differunt, sive signum nude significans, sive praetereà signati exhibitivum, habeatur: Utroque enim modo praedicatio evadit vel metonymica, vel synechdochica, eòque impropria. Priori quidem, per metonymiam signi pro signato; posteriori verò, vel per metonymiam continentis pro contento, vel per synechdochen partis pro toto. Confirmatur, sacramentalem propositionem ὁριστικὴν, suâ naturâ impropriam esse, Inductione etiam singularum Sacramentalium tam Veteris, quàm N. Testamenti, in ipsa quoque S. Coenae institutione, occurrentis.
