    Although not agreeing with M. Guerin in regard to the invariable antecedence of partial or total destiuction, or absence, of the nervous centres, as the cause of morbid muscular retraction, it must be admitted that his remarks are ingenious. As the point in question is one of scien- tific interest, I have made the subjoined extract from a memoir read by him before the A-Ccid6iny oj Sciences of Paris, which may serve as a summary of this writer’s ideas upon the etiology of congenital displacements of the joints, and among them, of congenital luxation, at the head of the femur. “ The observation of certain monstrosities presents to us in a striking manner the combination of these four orders of facts, namely, that in them may be observed, at the same time, a material lesion of the nervous centres, the retraction of the totality or of the greater portion of the muscular system, and of concomitant luxations; a rigorous relation between the seat, the extent, and the degree of the nervous lesion, and the seat, extent, and degree of the retraction ; and finally, a relation of direction, of extent, and of degree, between this retraction and the dislocations which it produces. “ I have already frequently shown you, in certain mon- strosities, tbe coincidence of a partial or total destruction of the central nervous system, with a retraction, more or less general, of the muscular system, and the deformation of nearly all the parts ot the skeleton, and particularly of
