A collection of eight articles and papers submitted to the Swedish Academy by Torbern Olof Bergman including his discovery, made when he was still a student and praised by Linnaeus, that the coccus aquaticus is not an insect but the egg of the leech. The other important paper in the collection is by Klingenstierna. 'After reading Dollond's paper [on lenses] Klingenstierna took up the problem of achromatic and aplanatic lens systems for theoretical investigation. In 1760 he published in Kunliga Svenska vetenskapsakademiens Handlingar a comprehensive theory for such lens systems, referring to Dollond's experimental results and mentioning that he had made Dollond aware of his proof that Newton's assertion was wrong. Klingenstiernia's important 1760 paper is now considered a classic contribution to geometrical optics, paving the way for the later works of Abbe and Gullstrand' (DSB). (10)
