Link: • Carl Linnaeus to Abraham Bäck, 2 April 1756 n.s.
Dated 2 april 1756. Sent from Uppsala (Sweden) to Stockholm (Sweden). Written in Latin.

Min Kiäreste Broder,

Per aliquot dies distractus negotiis innumeris non licuit vacare literis amicorum.

Heri succubuit filia D[omini] D[octoris] Rosen variolis. Inoculatio instituta fuit eadem die in filio, filia, nata Kioerning et nata Norreliana. Filiola Kiörning feliciter absolvebatur; sat violenter affligebatur filius Rosen. Filia variolis confluentibus contaminata periit. Periclitatur adhuc magnopere Norrelia; et ulcus, ubi inoculatio instituta, sanie fluit copiosissime, ut chirurgi metuant magnopere, quod pars laedatur, sed nondum vita evasit. Plures qui praepararunt natos suos, ut inocularentur, inoculationi jam cessant, postquam familiam D[omini] Rosenii tamdiu cruciatam et mactatam praemissis incurrisse variolas confluentes, et filiam succubuisse, ubi omnes aliae infantes evasere sine arte, in urbe; rarissime enim auditum, quod hac tempestate s[ive] epidemia aliquis infans perierit. Doleo jacturam D[omi]ni Rosenii, ejusque conjugis, qui amisere natam pulcherrimam; mater dolet tanto magis, quod credat flliam vixisse abs arte, sed periisse arte sua.

Miser Söderberg, si capite damnetur; doleo juvenem animo mitissimo ita seductum fuisse.

Prodiit Browne Historia naturalis Jamaicae, quae erit opus egregium.

. Some of these persons had been taken seriously ill by the inoculation, but only von Rosénstein’s daughter had died. However, many parents who had decided to have their children inoculated have changed their minds, since they think that the inoculation brought about the girl’s death. You hardly ever hear that a child has died from smallpox during the current outbreak.

Linnaeus is saddened by the von Rosénstein family’s loss, and the girl’s mother [Anna Christina Rosén von RosensteinRosén von Rosenstein, Anna
(1718-1782). Swedish.
Wife of Nils Rosén von
Rosenstein, born von Hermansson.
] mourns the more since she thinks that it was the inoculation that caused her death.

Linnaeus would be sorry if Olof SöderbergSöderberg, Olof Swedish.
gets the death sentence. It is a pity that a young man of such a mild temperament has been so badly misled.
