Link: • Carl Linnaeus to Abraham Bäck, 25 February 1757 n.s.
Dated 1757 d. 25 febr.. Sent from Uppsala (Sweden) to Stockholm (Sweden). Written in Latin.

Amicissimo suo,
D[omino] D[octori] A[BRAHAM] BAECK,
S[alutem] p[lurimam]
Car[olus] Linnaeus.

Spero S[erenissimam] Reginam et per consequens etiam Te melius valere. Quaeris a me, quid praestiterit B[eatus] Hasselquist, sed novisti aeque bene ac ego.

Legit plurima pulchra insecta, in Museo Reginae descripta.

Detexit Serpentes varios; docuit veram viperam ab officinis pessime derelictam.

Descripsit numerosos Aves et Pisces, omnibus aliis melius.

Plurima in pharmaceuticis simplicibus collegit; descripsisset, si vixisset.

Plantas Palaestinae legit, ut Flora inde potuerit confici, tamdiu in votis a doctis theologis.

Fossilia Palaestinae, Aegypti aliis omnibus magis sollicite collegit, ut vidisti in Museo Reginae.

Observationes habet in omni historia naturali, medica, oeconomica.

Anne unica flora Palaestinae sufficeret? Vide acta Gottingensia, ubi adeo desiderata; et hujus ignarus Rex Danorum impendit hujus caussa 30,000 imperialium.

Qui non attendunt ad scientiarum augmentum, haec non curant, uti vulgus. Tu novisti, quot observationes concurrant, ut singulas partes exstruantur; videbis etiam in systemate naturae, quam multa etiamnum laterent, si ejus ignota fuissent. Vale!

Upsaliae 1757 d[ie] 25 febr[uarii].

Linnaeus hopes that the Queen [Lovisa UlrikaLovisa Ulrika, (1720-1782).

are well.

Bäck has asked what Fredrik HasselquistHasselquist, Fredrik

had achieved, but Bäck should know that as well as Linnaeus himself. However, Linnaeus specifies:

He has collected several insects, now described in Museum Reginae.

He has discovered various snakes and shown that the common viper has been erroneously neglected in medicine.

He has described numerous birds and fishes, better than most.

He has collected many species for simple pharmacy, and he would have done more if he had lived.

He collected plants in Palestine to make a Flora, so long requested by theologists.

He has collected fossils in Palestine and Egypt, also published in Museum Reginae.

He has made many observations in natural history, medicine and economy.

Would not the Flora PalaestinaLinnaeus, Carl Flora

alone be enough? The King of Denmark [Fredrik VFredrik V, (1723-1766).
Danish. Reigned Denmark and Norway
] has assigned 30,000 imperialia for that purpose, ignorant of Hasselquist.

Those who do not pay attention to the progress of science do not care about these things, but Bäck knows how many agreeing observations are needed to make a complete picture. A good example of that is Systema naturae, where you can see how much would still be hidden if you did not investigate.
