Having seen with my own eyes the wonderful results of this treatment during my visits to the American Ambulance and other hospitals in France, I requested Mr. Laurence V. Benet, superintendent of the American Ambulance, to furnish me with an authoritative description of the treatment. The chief purpose of this is to enable medical authorities in this country, particularly those connected with hospitals maintained by iron and steel plants, to gain a reliable outline of the treatment. Dr. Benet, in spite of the fact that he is one of the busiest men in France, kindly agreed to furnish this information. In doing so he accompanied the description with the following letter: * * * 1 Avenue De Camoens Paris, October 26, 1916. Mr. Joseph G. Butler, Jr., Youngstown, O. My dear Mr. Butler:-- In compliance with my request, Dr. Joseph Lawrence, of the American Ambulance, has kindly prepared a short note on the Carrel treatment of wounds, and this I am now enclosing. I trust that you will find it sufficiently explicit for your purposes, and that it will be of use and interest to you. Now that you are again home I hope that your wonderful trip in France will be less than a mere memory and that the labors of the Industrial Commission will prove, as they should, most valuable to the manufacturers and exporters of the United States. Believe me that it was to me a great privilege as well as a great pleasure to have met you and your distinguished colleagues, and that my only regret is that I was unable to be of greater use to the Commission. I am, with very kind regards, Sincerely yours, LAURENCE V. BENET 1 encl. * * * The Carrel Treatment of Wounds. The Carrel treatment consists in thorough irrigation guided by the bacteriological observation of the wound. For the irrigation of the wound, Carrel has chosen a certain size of rubber tube about 4 mm. in diameter into which he punches small holes at intervals. The one end of this tube is shut, the other end is allowed to protrude from the dressing. On the surface wound, the tube is laid over the wound in the direction of the greatest diameter of the wound with the open end towards the most elevated part. In perforating wounds, the tube or several tubes, when the wound is large, are passed through from both sides, or pushed into cavities or pockets that may exist. If the wound is not a perforating wound, but a deep wound, the tubes are planted deep into the cavity that may be formed. These tubes are always of sufficient number to thoroughly irrigate the broken surface. Over the uninjured skin, about the wound, is placed thin strips of gauze which have been steeped in vaseline, the skin having been thoroughly washed before with soap and water.
