VIRO AMPLISSIMO,
D[omi]n[o] D[octori] Linnaeo,
S[alutem] P[lurimam] D[icit]
D[ominus] Ludwig.

Literas Tuas exoptatissimas circa finem praecedentis anni accepi, et cognovi spem meam de amicitia Tua continuatura non frustraneam fuisse, sed eum Te inveni qualem semper exoptaveram et amaveram. De rebus Tuis ex voto succedentibus maximopere Tibi gratulor et majora quoque laborum Tuorum praemia ex toto pectore Tibi apprecor. Maximopere tamen doleo, quod patriae redditus rebus botanicis adeo sis ereptus, ut omnem studium promovendi fervorem seposueris. Scio equidem praxin clinicam et rigorem climatis Vestri multum imminuere posse ardorem in promovendo studio olim adeo quaesito. Noli tamen omnimode seponere labores, qui Tibi hactenus ex voto successerunt. Perficias ad minimum ea quae olim promisisti. Perficias, quaeso, si omnia silentio tradere vis, Philosophiam Tuam botanicam.[1] Haec enim fundamentum totius studii videtur, quoniam definitiones continet, quas a nullo alio quam perfectissimo plantarum indagatore expectare possumus. Quae in Belgio aguntur Tibi forsitan jam nota sunt, e.g. BurmannumBurman, Johannes (1707-1779).

, cujus synopsis stirpium Germaniae[5] forsitan jam sub prelo sudat. Sed quid ego, Botanicorum minimus? Labores mei in Praxi clinica et in Collegiis Anatomicis, Physiologicis, Pathologicis amorem in plantas non quidem penitus supprimunt, sed tantum impediunt. Anno praeterlapso observationes in Methodum tuam Sexualem[6] promulgavi, non eo animo, ut me Tuis conatibus opponerem, sed ut confunderem nonnullos ex nostratibus, qui vix plantas indigenas cognoscunt et tamen magno cum impetu studio innovandi (dicam perficiendi), quod in Tuis scriptis invenire solent, sese opponere conantur. Quod si forsitan quaedam Tibi displicent, respondeas, quaeso, ad illa. Et nisi alio modo id promulgare velis, ego ipse responsionem Tuam collectoribus actorum eruditorum tradam, quo illis inseratur. Aphorismos botanicos[7] in usum Collegii mei Botanici editos Tibi mitto. Lubentius quidem illos retinere et imposterum emendatos Tibi tradere vellem, sed quo desiderio Tuo satisfaciam, nunc mitto et excusationem errorum nonnullorum, quam humanissime mihi expeto.

Quid Tibi est varietas et quomodo distinguitur a specie? Quomodo hic experimenta certa institui possunt? Multa ex Tuis perplacent. Quaedam experientiae meae contradicunt.

upSUMMARY

Christian Gottlieb Ludwig congratulates Linnaeus on his recent successes. Ludwig regrets that Linnaeus has returned to Sweden. Linnaeus should finish his Philosophia botanica, which contains definitions that can be expected from no one but the most brilliant explorer of plants.

In Holland Johannes Burman is publishing Georg Eberhard Rumph’s Herbarium Amboinense. In Leiden Johan Frederik Gronovius has published Flora Virginica and Adriaan van Royen Prodromus florae Lugduni Batavorum. In Germany all the botanists are silent except Albrecht von Haller, whose “Synopsis” of the German plants is perhaps now being printed. Last year Ludwig published his Observationes in Methodum plantarum sexualem Cel. Linnaei, in order to refute many of his German fellow-countrymen, who, although they hardly know the German plants, try to criticise Linnaeus. Linnaeus’s objections can be published in Acta eruditorum. Ludwig will send his Aphorismi botanici. He will soon publish De minuendis plantarum speciebus.

Ludwig asks Linnaeus to define a variety and to distinguish it from a species.

Johann Georg Siegesbeck’s Primitiae florae Petropolitanae will be sent. Siegesbeck has left St Petersburg. Johann Bernhard von Fischer offered Siegesbeck’s position to Ludwig, who declined.
