Interleaved fair copy of a draft of "Museum Ludovicae Ulricae" (1764) written by Linnaeus with corrections and additions on the interleaves and on inserted slips.
In the published catalogue, the order was inverted and started with insects, followed by shells.
Full title:
'Museum | Reginae | Sae Rae Mtis | Ludovicae Uldaricae [sic] | Svecorum Gothorum Vandalq[ue] | Reginae | in | cujus parte altera | Insecta | exotica | describuntur | redacta | ad | Classes Genera Species | cum | Synonymis figuris'
Small slips glued in in Linnaeus the Younger's hand on pp. 17, 109, 273, 279, 295. Some of these refer to plant genera (cf. p. 273, "Spigelia anthelmintica", and are close to traces of dried plants, indicating that Linnaeus the Younger might have used the volume to press specimens. The imprint of dried specimens can be clearly seen on numerous pages (see pp. 280-281, 312-313, 329-330, 368-369, 388-389...).
On p. 27, Linnaeus indicates that the specimen is in his collection by writing 'in Museo Linnaei'.
Between fol. 140 and 141 (Linnaeus's foliation, i.e. p. 293), draft of a letter from Linnaeus to te Chancellor of the University of Uppsala, Count Höpken on the introduction of the tea plant into Sweden, written on 12 November 1763, which can be determined from his reply of the 24 November. This letter is lost.
