Copybook with loose sheets, comprising two sets of notes on Linnaeus pater's lectures on 'Materia medica in regno lapideo'. The dissertation "Materia medica in regno lapideo" was defended on 15 May 1752 by Johan Lindhult (1723-1770), with Linnaeus pater as 'praeses'. It consisted of a compendium of 72 mineral substances prescribed by Linnaeus for medicinal needs arranged according to his classification and with pertinent mineralogical and medical data for each.
Linnaeus pater's lectures on the subject followed the same structure.
ff. 1-5: first set of note, incomplete, includes numbers 1 ("Silex") to 33 ("Hydragyrum"), very early hand;
ff. 6-18: complete set with all 72 mineral substances. With bits of string left onto pages, indicating it was once bound.
