De cautelis medicorum.

The first practical treatise on medical ethics. "Following opening remarks on the ideal conduct of the physician, and his duties towards his patients, their relatives, and his own colleagues while avoiding the perverse intentions of society in general, Zerbis systematically discusses six key areas in which the physician must seek to preserve himself from danger: his nature, character, and physical appearance; his training; his attitude toward God; and his attitude toward himself, and toward his patient; his relation to those present in the sickroom, the women, his disciples, ordinary folk, and druggists; and finally, the image he presents to the world at large outside the sickroom" (NLM cataloguing of this title.)
