It was, and must still be looked on as a most serviceable edition.
The edition published by Didot in 1857 has an altogether special character.
In the biographical notice M.Rathery for the first time treated as they deserve the foolish prejudices which have made Rabelais misunderstood, and M.Burgaud des Marets set the text on a quite new base.

Having proved, what of course is very evident, that in the original editions the spelling, and the language too, were of the simplest and clearest, and were not bristling with the nonsensical and superfluous consonants which have given rise to the idea that Rabelais is difficult to read, he took the trouble first of all to note the spelling of each word.

Whenever in a single instance he found it in accordance with modern spelling, he made it the same throughout.

The task was a hard one, and Rabelais certainly gained in clearness, but over-zeal is often fatal to a reform.

In respect to its precision and the value of its notes, which are short and very judicious, Burgaud des Marets' edition is valuable, and is amongst those which should be known and taken into account.
Since Le Duchat all the editions have a common fault.
