Among the noteworthy contributions to the science previous to 1850 are the writings of Dease (1808), Haslam (1817),[108] Christison, the successor of Professor Duncan in the University of Edinburgh, and best known as a toxicologist, Forsyth (1829),[109] Chitty (1834),[110] Watson (1837),[111] Brady (1839),[112] Skae (1840),[113] Pagan (1840),[114] and Sampson (1841).[115] In 1836, Dr. Alfred Swaine Taylor (b. 1806, d. 1880), the first Professor of Medical Jurisprudence in Guy’s Hospital, published his “Elements of Medical Jurisprudence.” This, the most important work upon the subject in the English language, is now in its twelfth English and eleventh American edition. During forty years of devotion to forensic medicine Dr. Taylor also contributed other important works and numerous papers, published for the most part in the Reports of Guy’s Hospital.[116] In 1844, Dr. Wm. A. Guy, Professor of Forensic Medicine in King’s College, published the first edition of his excellent work.[117] In 1858, Fr. Ogston, Professor of Medical Jurisprudence in the University of Aberdeen, published a syllabus and subsequently (1878) a complete report of his lectures.[118] In 1882, C. M. Tidy, Professor of Chemistry and Forensic Medicine in the London Hospital, who had previously (1877) been associated with W. B. Woodman in the authorship of a valuable handbook, began the publication of a more extended work, which was interrupted by his death in 1892.[119] The first Spanish work on legal medicine was that of Juan Fernandez del Valles, printed in 1796-97.[120] No further contribution to medico-legal literature was furnished by Spain until the appearance in 1834 of the work of Peiro and Rodrigo, which went through four editions in ten years.[121] Ten years later, in 1844, Pedro Mata, Professor of Legal Medicine and Toxicology at Madrid, published the first edition of a work, which in the development of its subsequent editions, has become the most important on the subject in the Spanish language.[122] The first Portuguese medico-legal treatise was that of Jose Ferreira Borjes, first printed at Paris in 1832.[123] A posthumously published report of the lectures of Albrecht von Haller was the earliest Swiss work on forensic medicine.[124]
