The dissertation highlights Linnaeus's conviction that infectious diseases could be transmitted by living organisms, too small to be seen. Biographies of Linnaeus often fail to mention that Linnaeus was correct in ascribing the cause of diseases such as measles, smallpox and syphilis to living organisms. The dissertation itself reviews the work of many microscopists, especially on zoophytes and insects, marvelling at the many unexpected discoveries. It then discusses and quotes at length the observations of M\u00fcnchhausen suggesting that spores from fungi causing plant diseases germinate to produce animalcules, an observation that Linnaeus claimed to have confirmed. The dissertation then draws parallels between these findings and the contagiousness of many human diseases, and urges further studies of this \u2018invisible world\u2019 since, as Roos avers, microscopic organisms may cause more destruction than occurs in all wars.<\/jats:p>","DOI":"10.1017\/s0007087416000637","type":"journal-article","created":{"date-parts":[[2016,10,10]],"date-time":"2016-10-10T13:57:00Z","timestamp":1476107820000},"page":"353-382","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":4,"title":["A translation of the Linnaean dissertation<i>The Invisible World<\/i>"],"prefix":"10.1017","volume":"49","author":[{"given":"JANIS","family":"ANTONOVICS","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JACOBUS","family":"KRITZINGER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2016,10,10]]},"reference":[{"key":"S0007087416000637_ref42","volume-title":"M\u00e9moires pour servir \u00e0 l'histoire des insectes","author":"de R\u00e9aumur","year":"1734"},{"key":"S0007087416000637_ref26","doi-asserted-by":"publisher","DOI":"10.1098\/rstl.1742.0101"},{"key":"S0007087416000637_ref10","first-page":"1781","volume-title":"Select Dissertations from the Amoenitates Academicae, a supplement to Mr Stillingfleets tracts relating to natural history","volume":"1","author":"Brand"},{"key":"S0007087416000637_ref13","first-page":"85","article-title":"Linn\u00e9s, Fundamenta ornithologica","author":"Insulander","year":"2000","journal-title":"Svenska Linnes\u00e4llskapets \u00c5rsskrift"},{"key":"S0007087416000637_ref41","volume-title":"Gametes and Spores: Ideas about Sexual Reproduction 1750\u20131914","author":"Farley","year":"1982"},{"key":"S0007087416000637_ref31","volume-title":"From Ergot to \u2018Ernutin\u2019: An historical sketch","author":"Wellcome","year":"1908"},{"key":"S0007087416000637_ref37","volume-title":"European Smut Fungi","author":"Vanky","year":"1994"},{"key":"S0007087416000637_ref19","volume-title":"A Selection of the Correspondence of Linnaeus and other Naturalists, from the original manuscripts","volume":"1","author":"Smith","year":"1821"},{"key":"S0007087416000637_ref8","doi-asserted-by":"publisher","DOI":"10.1017\/S0007087416000339"},{"key":"S0007087416000637_ref39","volume-title":"Order out of Chaos: Linnean Plant Names and Their Types","author":"Jarvis","year":"2007"},{"key":"S0007087416000637_ref17","volume-title":"R\u00e9aumur and the Practice of Natural History in the Eighteenth Century","author":"Terrall","year":"2015"},{"key":"S0007087416000637_ref6","volume-title":"The Compleat Naturalist: A life of Linnaeus","author":"Blunt","year":"1971"},{"key":"S0007087416000637_ref16","volume-title":"The Quest for the Invisible: Microscopy in the Enlightenment","author":"Ratcliff","year":"2009"},{"key":"S0007087416000637_ref34","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-782203-7.50018-2"},{"key":"S0007087416000637_ref25","first-page":"215","article-title":"Den Osynliga V\u00e4rlden.
