examination was made by Dr. (now Sir The abdominal walls were found to be covered with fat, an inch thick. The ileum, just above the caecum, was perforated by ulcers of a tuberculous character, of which there were several. Both lungs were strongly adherent at their apices, especially the left, and in both cretaceous matter was found-in the right varying in size from a pin’shead to a pea; but in the left lung there was a large mass of the same material, which quite filled the ancient cavity at the summit of the lung. This patient had been free from chest symptoms for eight years. This case is less remarkable for the duration of his life after recovery from the third stage of consumption than for the completeness of the cure of his chest-symptoms, and for the demonstration it afforded, after death from another cause, of the arrest of the tuberculous disease which had made rapid strides eight years before.

The entire venous system is engorged with the same kind of blood, more especially the large venous trunks. The liver is found hyperaemic, enlarged, and darkcoloured. The first effect of the poison in the system seems to me to damage the current of blood, by the cells of the poison perhaps deranging the vital affinities existing between the blood-corpuscles and the serum in which they float, and by that means the nervous centres are affected and nutrition arrested.

CASE OF

DISLOCATION OF THE HIP-JOINT CHILD SIX MONTHS OLD. BY JOHN

IN A

POWDRELL, ESQ., M.R.C.S.

ON the 23rd April last Mrs. C- brought her child to me little girl six months old,-having reason to think it had been injured by a fall. It was a well-nourished, average-sized child, and apparently very healthy. The history was, that about a week previous to the above date the child was placed in a small arm-chair, and secured there with a handkerchief tied from arm to arm. By accident, the chair and child were upset; and on the mother going to her assistance, she says she had some difficulty in extricating it, as it was doubled on its side over the left arm of the chair. The child cried a good deal on being loosed from its awkward position; still the mother did not then think it was seriously injured. After this fall the child appeared to give way on the left side, as if in pain somewhere; and (as the mother expressed herself) when she tried to make it feel its feet, it would resist putting its left foot down on to the floor. Placing the child on its back on the mother’s knee, and removing its clothes from the lower part of its body and extremities, the legs were seen to be drawn up and flexed on to the abdomen, with the knees inclining towards the middle line. On extending the legs the child screamed out, and more so when the legs were placed together. Now, on comparing the two sides, the nature of the injury was seen. The left leg was between an inch and an inch and a quarter longer than the right, the left toes were extended out, and the heel was drawn up; the left trochanter major was much less prominent than the right, and behind and above it there was a depression not discernible on the right side. From these symptoms I at once came to the conclusion that it was a case of dislocation of the head of the femur, downwards and forwards, on to the obturator externus. My partner, Mr. Luke, coming in at this time, came to the same diagnosis. Grasping, as it were, the left side of the pelvis with my left - -a

AN IMPROVED TROCAR AND CANULA FOR PUNCTURING THE BLADDER PER RECTUM. BY

JOHN

D. HILL, F.R.C.S.,

SURGEON TO THE ROYAL FREE HOSPITAL.

IN surgical practice cases of retention of urine are sometimes met with which require the operation of puncture of the bladder per rectum and the retention of the canula in the bladder until a catheter can be introduced through the urethra. Having had some experience in this form of treatment, I have directed my attention to a defect in the instrument now used, which in some cases is attended with a chance of local mischief, and in all cases with discomfort to the patient. This instrument is so constructed that the canula is beveled to a sharp edge on the point of the trocar, for the double purpose of allowing it to slide with the trocar through the coats of the bladder without obstruction, and at the same time to spring over the bulb of the trocar by means of a fissure inserted in one or two of its sides. Hence it will be seen that when the trocar is withdrawn, and the bladder emptied, its walls are in actual contact with the sharp edge of the canula. Further, both ends of the canula being always open, the urine trickles away, keeping the patient constantly wet and uncomfortable. To remedy this defect I have lately passed an elastic bougie through the canula, securing it to the outer lip by a piece of tape. Carrying out this principle, Messrs. Weiss and Son have, under my direction, constructed an inner canula, with one end shut and rounded, to project beyond the sharp edge of the outer canula, while the outer end is locked to the lip of the external canula, a small ring being fixed to it as a handle. Thus when the bladder has been relieved by puncture, and the canula secured with tapes, the internal canula is introduced and fixed. By this means the external canula can be retained with perfect safety and comparative comfort, the urine being drawn off as may be required. This instrument answers so well that I am induced to ask my professional brethren to give it a trial. Guildford-street, May, 1868.
