First edition of Mead's work on smallpox and measles, which includes a Latin translation of Rhazes work. Mead favoured inoculation, and his great authority and influence helped towards a more general acceptance of this measure. Rhazes account is so vivid and complete that it seems almost modern. Certainly for Mead in the eighteenth century it was current enough, and even today it may be studied for its clinical value as well as its historical interest. (Garrison-Morton).
