The presence of the paraffin will not interfere with the successful performance of the open operation nor will it complicate the operation so that the chances of a radical cure are not diminished from this method, nor is the patient liable to a slower convalescence. Vehement protests against the use of paraffin injections are to be expected from surgeons doing the open operation, and unbiased readers should not be misled by condemnatory remarks from inexperienced sources. PREPARATION OF THE SKIN. The hair over the pubes and the groin of the affected side should be cut rather close and then the parts scrubbed with a solution of green soap. A small amount of a forty per cent. solution of formaldehyde may be added to the soap solution as this agent is a very powerful antiseptic. Soap solution. Formaldehyde solution, one dram (40%). Green soap, four ounces. Dilute alcohol to make one pint. The dilute alcohol is made up of equal parts of ninety-five per cent alcohol and water. After the parts are thoroughly scrubbed with this solution the soap should be removed with moist compresses and then the parts mopped with a solution of seventy per cent alcohol. Finally the field of operation should be flooded with ether as this agent is an effective antiseptic and also acts as a solvent for any greasy matter not removed by the soap. PREPARATION OF THE HANDS OF THE OPERATOR. Antiseptics cannot be as freely used upon the hands of the operator as upon the skin of the patient as the repeated application of the stronger antiseptics cause a scaling of the epithelial cells and finally the development of an irritated state which prevents cleansing of the hands sufficiently to permit operating. It is well to scrub the hands with the soap solution and then to follow with the use of the seventy per cent alcohol. The alcohol solution is the least irritating of effective antiseptics and it is the solution in which needles and leather washers should be kept, so that they are at all times ready for use. THE SYRINGE. The sterilized paraffin syringe should not be handled until the hands have been scrubbed. The washers and needles, just before using, should be removed from the alcohol solution. It is unnecessary to wash the alcohol from the fingers, washers or needles, in fact, it is preferable to leave it upon them. Using an extra large syringe it is possible to operate upon several patients without resterilizing the syringe. This instrument may be soaked in the alcohol solution, the needle changed and the operator may continue until the syringe is empty.
