Short paper on ergotism, attempting to explain an outbreak of the disease in the southern provinces of Sweden (Småland and Bleking) in 1754 and 1755. Linnaeus gave its cause as the plant "Raphanus raphanistrum" growing in the fields there.
Two copies, both in Linnaeus's hand, the fuller version signed "C. Linnaeus". Apparently presented to the Academy of Science.
Not published in this form, later version as the dissertation "Raphania, 1763, resp. Rothman".
