[1] (_Appareil._) I am fully sensible that the word Apparatus, does not, according to the common acceptation of the term, convey, in English, precisely the same ideas, that the word “_appareil_” does, in French; but it certainly approaches much nearer to it than any other term found in English works on surgery. It signifies a collection or assemblage of means, used for the attainment of a particular end; and this is, in substance, what Desault meant by the term “_appareil_.” His “appareil” (apparel) for a broken bone included splints, bandages, bolsters, and every thing else necessary for retaining the fractured ends in apposition. The English reader will naturally enough annex the same ideas to the word Apparatus, as used throughout the present work. I have, therefore, thought proper to adopt it, rather than to introduce a new or uncommon term, and am sure, that, for all practical purposes, it will be found sufficiently expressive of the meaning of the original. And I am much more solicitous to become instrumental in giving some aid to the surgeon in the practice of his profession, than to escape the censure of the fastidious critic.
