Note 33 — PRELIMINARY DISCOURSE.
Francis Adams translation
Galen, in many parts of his works, alludes to the professional services of Hippocrates during the great plague described by Thucydides. He mentions decidedly that Thucydides gives only those symptoms which would strike a common, that is to say, a non-professional man; whereas Hippocrates describes the disease accurately like a professional man, but gives few of those symptoms which appeared most interesting to Thucydides.—De Difficult. Respir., ii., 7.
