The frequent occurrence of fracture of the ribs in the inmates of Lunatic Asylums has recently attracted much attention. And the more attention has been called to it, the more frequent does the occurrence seem to have become. This fact alone would make one suspect that the injury was not due to improper violence on the part of the attendants. Without, however, entering into this question, I propose here merely to record the results of my examination of the bones of two patients who lately died in the Sussex County Lunatic Asylum with fractured ribs. Whether or not further observation may justify a wider extension of the conclusion that the bones break so readily because they are diseased, at least I cannot hesitate to adopt it in the present instance.
