It has been my principal care to convey the precise meaning of my author, and also to preserve the genius of his style, where the English idiom would allow. I have likewise been careful not to wrest any expression of Celsus, in order to deceive the reader into a greater opinion of his knowledge, than he really deserves. His merit is sufficiently great without pretending to find in him any discoveries, the honour of which is due to the moderns. Every man of learning, who is acquainted with the state of physic among the ancients, and knows how far it differs from the modern, must be sensible of the difficulty of translating an author so elegant and concise, with the strictness necessary in a work of this nature. Such judges, I hope, will censure the faults, which cannot escape their observation, with the candour inseparable from true criticism. It only remains, that I return thanks to my ingenious and learned friends of the faculty, who have favoured me with their opinions on several passages, particularly to Dr. Maghie of Guy’s hospital.
