III. Concerning the opinion 57 that Mercury cures Lues Venerea, by acting as an Antidote to the Venereal Matter IV. Of the different 86 Mercurial Preparations employed in Medicine V. Of the Mercurial 98 Preparations intended to act immediately upon the Parts affected with Lues Venerea VI. Of the Mercurial 117 Preparations intended to act in the cure of Lues Venerea, by entering the System VII. Of the Cautions to be 146 observed in the Employment of Mercury in Lues Venerea ------------------------------------------------------------------------ PREFACE. THE chief purpose of the study of medicine is to acquire the knowledge of a safe and effectual method of curing diseases. The attainment of this end is intimately connected with the public good. Every endeavour to promote it, therefore, may be considered as having some claim to a candid examination. In this persuasion, I submit the following observations to public inspection. Few diseases are at present more common than _lues venerea_. For its cure, mercury is a medicine which is almost universally employed; and the efficacy with which it operates has long been confirmed by unquestionable experience. But the successful employment of mercury in this disease requires very particular attention; and it is to be regreted, that, while many suffer from the distemper, not a few fall victims to what is used as the remedy: All therefore that has hitherto been said on this subject by no means supersedes farther attempts to improvement. To advance the practice of medicine in this particular, is the intention of the present publication.
