    congenital displacements without absence of some portion of the central nervous system, nor could there be any foetal aneucephalous monstrosities, without the existence of numerous luxations or subluxations. As soon as the correlation of circumstances, reported by M. Gu6rin, is found to be at variance with facts, the generalization he has adopted, must be pronounced falla- cious. Now, aneucephalous foetal monsters are to be met with, in which no dislocations of the articulations are present, and it is no uncommon event to see congenital dislocations attributable to muscular retraction—not only of the hip-joints,—but also of many of the other articula- tions, without any palpable absence of the nervous centres. Thus, in those cases I have to relate hereafter, and from which I have had the drawings taken, there was no absence of the nervous centres apparent, nor in the cases related by Palleta and Dupuytren, is the absence of any portion of the spinal marrow or of the encephalon al- luded to. The physiology of the nervous system, and its influ- ence over muscular contraction, will nevertheless induce the inquirer to look to the centres of this system as the source, whence is radiated the pathologic influence, which manifests itself in the muscles, in the form of morbid muscular retraction, and upon which probably depend many congenital dislocations, and among them the dislo- 6
