Louis van Ledden Hulsebosch, father of Dutch forensic pioneer Co van Ledden Hulsebosch, starts the prepublication of his monumental work “Makro- und mikroskopische Diagnostik der Menschlichen Exkremente” with the words “Of the many disciplines that are practiced there are few that are so interesting, but none that is practiced so scarcely as the microscopic examination of human excrements” (translation of the Dutch original manuscript).
Recently this prepublication (in Dutch) (Originally published in Ned. Tijdschrift voor Geneeskunde, Jaargang 1897, 2de Deel) has been made available digitally by his great grandson Co van Ledden Hulsebosch Jr.
