CHEVALIER ON GUN-SHOT WOUNDS. In a former number wre have given a translation from a elistinguished French writer on ibis subject. It will be useful tbcompare the opinions in that publication with those of the author, whom we here
... hom we here introduce. Mr. Chevalier is an English surgeon, of the highest reputation. His book has been received in the most favourable manner, three éditions having be-en published in no long space of time. The following may be considered as an epitome of the most important practical parts of his work. A gun-shot wound is a wound made by a blunt instrument impelled with great velocity into the living solid. A wound of this description must therefore necessarily produce more or less of contusion and laceration of the wounded parts ; will often be accompanied with hicmorrhagc, the fracture of a bone, and in many instances with the lodgment of extraneous substances. By contusion the texture of some fibres will be weakened, that of others will be broken through, and some portions will be absolutely killed. Those which are dead must be separated ; and to effect this will be the first operation of nature. The portion removed is called the eschar or slough. This is not always confined to what is evidently destroyed, but often extends to portions, which have been very much weakened, or whose source of nourishment has been cut off. A large artery may be so injured by contusion as to slough, and a violent anel even fatal haemorrhage may take place at the formation of the eschar. If the contusion has been slight, and there is no external wound, the dead particles may be absorbed and the part restored without an eschar.
