From page 400: "Manna seri hæc. Destilla leni balnei calore serum lactis, donec in fundo vasis butyracea fœx subsideat, cui hærebit salina quædam substantia subalbida. Hanc curiose segrega, est enim sal seri essentiale; seu nitrum, cujus causa nitrosum dicitut serum, huicque tota abstergedi vis inest. Solve in aqua propria, & coagula. Opus repete, donec seri cremorem habeas sapore omnino mannam referentem." (This is the manna of whey. [Note: "Manna" is the dried, sweet sap of the tree Fraxinus ornus.] Gently distill whey via a heat bath until the buttery scum settles to the bottom of the vessel, to which substance some whitish salt [i.e., precipitate] attaches. This curious [substance once] separated, is truly the essential salt of whey; or, on account of which nitre, is called "nitre of whey", and all [life] force is in this that will be expelled. [Note: "Nitre" is an alchemical concept. It is the power of life, which gives life to otherwise inanimate matter. (See the philosophy of Sendivogius.)] Dissolve it in [its] own water and coagulate. Repeat the operation until you have cream of whey, recalling, by [its] taste, only manna.) In 1688, the German physician Michael Ettmüller (1644–1683) reprints Bartoletti's preparation. See: Ettmüller, Michael (1688). Opera Omnia… Frankfurt am Main ("Francofurtum ad Moenum", Germany): Johann David Zunner. 2, page 163. From page 163: "Undd Bertholetus praeparat ex sero lactis remedium, quod vocat mannam S. [alchemical symbol for salt, salem] seri lactis vid. in Encyclopaed. p. 400. Praeparatio est haec: … " (Whence Bartoletti prepared a medicine from milk whey, which he called manna or salt of milk whey, see in [his] Encyclopedia [note: this is a mistake; the preparation appeared in Bartoletti's Methodus in dyspnoeam … ], p. 400. This is the preparation: … )
