There are cases that resist treatment of the kind described above. Diet and drugs do not succeed in establishing the habit of daily bowel movements. In these cases radical treatment is imperative. The diet should be the same as that described above, but it will be found advisable to cut out milk altogether. Cereals can be taken with sugar and butter instead of milk. The oil injection plan of Professor Kerley has given me excellent results. I quote his comments upon and method of giving it:-- "OIL INJECTIONS."--"For this purpose a soft-bulb syringe of four ounces' capacity is ordered. Over the hard rubber tip is place a small sized adult rectal tube or a No. 18 American catheter. The catheter or tube is cut so that but nine inches remain for use. The cut end is forced over the small, hard rubber tip of the syringe. A fountain syringe is impracticable for this purpose, as it is soon destroyed by the oil and rendered unfit for use. Besides, sufficient pressure is not produced to force the oil into the gut even with a high elevation of the bag. The child is placed on his back or on his left side. The syringe is filled with oil, the tube is lubricated, and passed through the rectum as far as it can go. When it has been passed to the full nine inches, as may readily be done with a little practice, the syringe is emptied and the tube withdrawn. The injection should be given after the child has been placed in bed for the night. It is our object to have the oil retained during the night. If a passage of the bowels is produced at the time, or if the oil leaks out during the night, a small quantity should be used. In some of my patients I have been able to use but one ounce. In very few, indeed, does it cause an evacuation at the time. If there is a tendency to leakage a napkin should be worn to avoid soiling the bed-linen. The following morning after breakfast, the child is placed on the vessel and kept there until a bowel movement results or until fifteen minutes have elapsed. In a great many cases if the constipation has been obstinate for months, the bowel will be at once evacuated. When this does not occur in fifteen minutes, a glycerine suppository is inserted, which invariably produces an evacuation. This use of the suppository, according to my observation, can usually be dispensed with in a very few days; the use of the oil, however, may have to be continued for several weeks. When the child has had the oil nightly and an evacuation the next morning without assistance for two weeks, I direct that the oil be omitted for a night and the effect noted. If the usual passage occurs after breakfast, the oil is given for five nights and then omitted. If the case progresses satisfactorily the use of the oil is gradually omitted, being given at first every second night, then every third, fourth, or fifth night, etc. A considerable number of cases have been completely relieved in two months. In the event of no passage
