1835. Small folio, pp. [viii], 36,  duplicate leaf of pp. 35-6,-44,  explanation to plates and vitae curriculum; with four engraved plates, one partially hand-coloured in blue and red, and signed ‘Franz Wagner del, C. Guinard sc’; title-page somewhat browned, with further browning and foxing throughout, plates quite prominently foxed and browned, corners a little furled, with a few small marginal nicks and tears, ink accession number at upper margin of title-page with very faint blindstamp at tail; sympathetically rebound in modern black marbled papers to style, with some light wear to joints and extremities. A detailed dissertation on pathological anatomy, focusing upon human and animal abnormalities, and in particular the various types of bone fissures. For a doctoral thesis it is surprisingly well produced in the larger folio format, using appealing typography and including four finely engraved plates illustrating the head of a young lamb or calf.
Conrad Meyer-Ahrens (1813-1872) was a Swiss physician and medical historian. He studied at the Friedrich-Wilhelms-Universität Berlin where he publicly defended the present dissertation. The dedication is to his teacher, Johannes Müller.
