In fractures about the pelvis the Eontgen rays, so far as onecan judge, are not likely to help the surgeon much. The hip,again, is deeply placed, and so far satisfactory results are notalways attainable. However, much is often to be learnt in thecase of children and young adults, in one case a fracture of theneck of the femur was shown in a muscular adult, six feet in.

It will be wise to try and secure a record of impactedintracapsular fracture of the hip, because of its frequent after-shortening, which may be attributed by patients to unskilfultreatment. Under such circumstances a differential photograph,showing an alteration in form or relation of the injured side,might be of the utmost value to the medical attendant. Coxa Vara.—Mr. Lynn Thomas has communicated the case ofa young man aged about eighteen who injured his hip in playingfootball. From an examination of his signs and symptoms, somemonths after the original injury, he would have concluded thatabsorption was taking place of the head of the bone, most likelyafter impaction into it of the neck. An examination by the #-rays,however, showed the bending of the neck of th
