The first edition of the earliest Pharmacopoeia, or the standard 'recipe book' of medical compounds, to be printed in English. Developed by the Royal College of Physicians of London, who had published the compendium in Latin for the 170 years prior, this edition was rapidly reprinted, reaching three editions in its initial year. Healde's work would influence the research of John Latham, whose revised, and adapted, fifth edition would supersede it in 1791.
