For my own Particular, when after reading the Introduction to the Work, and much of the Sequel, I had determined to translate it; to be as just as possible to the Author, and to his _English_ Readers, I determined not to interpolate any Sentiment of my own into the Text, nor to omit one Sentence of the Original, which, besides its being _Detraction_ in its literal Sense, I thought might imply it in its worst, its figurative one; for which there was no Room. To conform as fully as possible to the Plainness and Perspicuity he proposed, I have been pretty often obliged in the anatomical Names of some Parts, and sometimes of the Symptoms, as well as in some pretty familiar, though not entirely popular Words, to explain all such by the most common Words I have heard used for them; as after mentioning the _Diaphragm_, to add, or _Midriff_--the _Trachaea_--or _Windpipe_--_acrimonious_, or _very sharp_, and so of many others. This may a little, though but a little, have extended the Translation beyond the Original; as the great Affinity between the _French_ and _Latin_, and between the former and many _Latin_ Words borrowed from the _Greek_, generally makes the same anatomical or medical Term, that is technical with us, vernacular or common with them. But this unavoidable Tautology, which may be irksome to many Ears, those medical Readers, for whom it was not intended, will readily forgive, from a Consideration of the general Address of the Work: while they reflect that meer Style, if thoroughly intelligible, is least essential to those Books, which wholly consist of very useful, and generally interesting, Matter. As many of the Notes of the Editor of _Lyons_, as I have retained in this Version (having translated from the Edition of _Lyons_) are subscribed _E. L._ I have dispensed with several, some, as evidently less within Dr. _Tissot's_ Plan, from tending to theorize, however justly or practically, where he must have had his own Reasons for omitting to theorize: a few others, as manifestly needless, from what the Author had either premised, or speedily subjoined, on the very same Circumstance: besides a very few, from their local Confinement to the Practice at _Lyons_, which lies in a Climate somewhat more different from our own than that of _Lausanne_. It is probable nevertheless, I have retained a few more than were necessary in a professed Translation of the original Work: but wherever I have done this, I have generally subjoined my Motive for it; of whatever Consequence that may appear to the Reader. I have retained all the Author's own Notes, with his Name annexed to them; or if ever the Annotator was uncertain to me, I have declared whose Note I supposed it to be.
