Case 7 A. Y.--Femoral hernia. Female, age 35, A. C. C. Disp. Worker in tailor shop. History of case indefinite as to length of time present. Never been treated in any way. Operation March 21, 1906. Injection of forty minims of paraffin through saphenous opening and about ten minims through Poupart's ligament. Codeine discontinued at end of fourth night. Tenderness slight. No recurrence at end of twenty days. Patient not seen subsequently. Case 8. Case 8 E. H.--Marshalltown, Iowa. Private patient. American born. Varicocele on left side and oblique inguinal hernia. Operation April 16, 1906. Infiltration and removal of dilated veins in scrotum. Wound closed and inguinal canal followed by large needle. No blood aspirated and cold paraffin mixture with melting point 115 injected along canal. About forty minims thrown along canal and then puncture made at site of internal ring and half dram diffused at this point. Personal communication one year later making final payment for operation. Patient cured and grateful. Case 9. Case 9--Italian section worker wearing spring truss for holding of inguinal hernia. Strong pressure of truss making marked depression at site of internal ring. Patient injected with dram and half of paraffin of melting point 115. May 20, 1906. Agent deposited along canal and at internal ring. One week later no pain, no tenderness to moderate pressure. Cord somewhat larger than normal and epididimus thickened but not tender. Shreds in urine. Through interpreter information gleaned that epididimus had been somewhat tender following operation. History of acute epididimitis some months before. Case 10. Case 10 A. J.--Patient first consulted at Harvey dispensary. Treated for urethral stricture by internal urethrotomy. Subsequently referred to A. C. C. Disp. for treatment. Developed acute appendicitis and operation for removal after development of abscess. Abscess drained and healing of abdominal incision imperfect leaving hernial protrusion internally and near superior angle of scar. Injected with seventy minims of paraffin, 115 melting point, on Aug. 2, 1906. No pain following injection, no discoloration, and no recurrence over a year and a half after operation. CONCLUSION. These cases represent the ten first which were seen subsequent to injection. Cases which were injected and which did not return subsequent to injection have not been included as they would be of no value in estimating as to the usefulness of this method. In no instance has an ill consequence been suffered which would cause the patient to seek surgical aid elsewhere, or at least no case has come to the knowledge of the author directly or indirectly.
