Le Clerc questions the authenticity of this epistle, but seems to have had no other grounds for his scepticism than the general suspicion which has attached to all the Epistolæ Græcanicæ since the memorable controversy between the Honorable Mr. Boyle and Dr. Bentley on the authenticity of the Epistles of Phalaris. It is published in the ‘Bibliotheca Græca’ of Albertus Fabricius, who appears to have been satisfied as to its genuineness. Mr. Moir, the author of ‘Outlines of the Ancient History of Medicine,’ condemns it as apocryphal, upon the authority of Schulze. (p. 76.) All we shall say on this point is, that the evidence against the authority of this Epistle appears to us to be very inconclusive. BOOK SECOND. SECT. I.—ON FEVERS, FROM THE WORKS OF GALEN AND SEVERAL OTHERS. After having treated of those things which relate to the preservation of health, we now come to the treatment of persons already in disease, and shall begin with homogeneous disorders as being the most simple. These are what are called Fevers. Wherefore, using again principally Oribasius’ Epitome of the Works of Galen and several others on this subject, we shall add a very few things omitted by them. * * * * * COMMENTARY.
