While _Salin_ was thus engaged on the subject of poisoning, _Lafosse_ sought to distinguish the phenomena produced by death, from the traces of violence inflicted during life upon the body. He, moreover, developed the unequivocal signs of pregnancy and parturition. _Professor Chaussier_, in the year 1789, by a memoir, to the Academy of Sciences at Dijon, on the great importance of the study of juridical medicine, excited a spirit of emulation which was productive of the highest advantage. At about this period also the memorable “_Encyclopédie Méthodique_,” was undertaken, in which the celebrated authors already named contributed their powerful assistance, in conjunction with _Professor Mahon_, in compiling the elaborate articles upon Medical Jurisprudence. Such were the materials, says _M. Foderé_, which enabled me to publish my first systematic work[39] on this science in the year 1796. In the first few years of the present century the science of juridical medicine received numerous contributions from the French physicians. _M. Vigné_, of Rouen, published in 1805 his humane and enlightened reflections upon its practical applications; a work which bears internal evidence of the science as well as the judgment of its author. In the year 1807, the system of _Professor Mahon_ appeared, not, however, until after the death of its author; _M. Fautrel_ having undertaken the charge of arranging the manuscript, of illustrating it with notes, and of giving it to the world.[40] Nearly at the same time the small, but useful work of _Belloc_[41] was published; and in the following year _Marc_[42] translated the German manual of _Rose_ on juridical dissection, and enriched it with original observations; to which he also subjoined two memoirs on the obscure subject of the “_Docimasia Pulmonaris_.” We have deemed it necessary to introduce to our readers this slight sketch of the literary history of Medical Jurisprudence in relation to its progress in the several countries of Germany, Italy, and France; for much of the information thus afforded we are indebted to the elaborate system of _Professor Foderé_,[43] published in six volumes, in the year 1813, and which must be regarded as a new work, rather than the republication of that already noticed, as having appeared in 1796. From this voluminous treatise we have frequently, in the progress of our present undertaking, made copious extracts. It becomes our duty therefore to present our reader with some account of the extent of its objects, and the order of their arrangement. The author divides his work into three parts, viz. the _First_ comprehending subjects of a mixed nature, or those which admit of application to civil as well as criminal cases, “_Médecine Légale mixte_.” The _Second_ exclusively relating to criminal jurisprudence, “_Médecine Légale Criminelle_;” and the _Third_, to medical police, “_Médecine Légale Sanitaire_.”
