Begins 'Amphibia äro desse af äldre tider kallade'.
Several sets of notes about 'Amphibia', of various dates.
Notes on quarto sheets mostly in Swedish, notes on folio sheets mostly in Latin, sometimes being translations of the Swedish notes.
Quarto sheets (ff. 1-37) cover notes about 'Amphibia' in general, and the genera "Testudo", "Draco", "Petromyzon", "Raja", "Squalus", "Accipenses", following the arrangement of Linné, Carl von. 1766. "Systema naturae". Stockholm (12th edition).
Also contains notes on snake bites and cures (with the plant 'Senega', or "Polygala senega") on ff. 17-21.
Drawing on f. 37.
Folio sheets (ff. 38-56) cover notes about the genera "Testudines", "Lacertae" (including "L. crocodylus", "L. Monitor", "L. chamaeleon", "L. salamandra", "L. stincus", "L. gecko", "L. iguana"), "Ranae" ("R. pipa", "R. musica", "R. buffo", "R. bombina", "R. paradoxa", "R. temporaria", "R. esculenta", "R. arborea", "R. boans"). Also covers notes on snake bites and their cures (translation from the Swedish above), ff. 55-56. The folio sheets seem more varied in dates: notes on "Lacerta monitor" indicate that it is the fifth species of "Lacerta", as in "Systema naturae" 1758 (10th edition), whereas species of "Ranae" follow "Systema naturae" 1766 (12th edition).
