Dictionnaire universel de médecine, de chirurgie, de chymie, de botanique, d'anatomie, de pharmacie, d'histoire naturelle, &c. Précédé d'un discours historique sur l'origine et les progrès de la médecine. Traduit de l'anglois de M. James. Revue, corrigé & augmenté par M. Julien Busson. 6 vols.

James, it may be assumed, had little or nothing to do with this translation, because copyright between England and France was essentially non-existent at the time. In the process of supervising this large publication, Diderot collaborated with three "philosophes", of which only Busson was a physician. Experience with this publication gave Diderot the idea of undertaking the much larger scale project, the Encyclopédie des sciences.
