This consisted during the campaign in the primary application of the regulation first field dressing by one of the wounded man's comrades, an orderly, or less commonly an officer or a medical man. This dressing is composed of a piece of gauze, a pad of flax charpie between layers of gauze, a gauze bandage 4-1/2 yards long, a piece of mackintosh water-proof, and two safety pins, enclosed in an air-tight cover. Mr. Cheatle,[13] in insisting on the importance of an immediate antiseptic dressing in the field, recommends the following. A paste contained in a collapsible tube, made up in the following proportions: Mercury and zinc cyanide grs. 400, tragacanth in powder gr. 1, carbolic acid grs. 40, sterilised water grs. 800; sufficient bicyanide gauze and wool for the dressing of two wounds, a bandage, and four safety pins; the whole enclosed in a mackintosh bag. The paste possesses the advantage over any liquid or powder, that it can be applied in any position of the body to severe wounds, and its application in the open air is not interfered with by draughts of wind. Mr. Cheatle used a similar preparation with success during the campaign. On arrival at the Field hospital, or in some cases at the station of the bearer company, the wounds were then commonly dressed as follows: The parts around the wound were cleansed with an antiseptic lotion, either solution of perchloride of mercury 1 in 1,000, or 2-1/2 per cent. solution of carbolic acid. The wound itself was then cleansed, and a dressing of double cyanide of mercury and zinc applied. This was covered with a pad of wool and secured with a bandage. The gauze was usually wrung out in the lotion before application as a precaution against previous contamination, and the moistening was also useful as helping to ensure the dressing from subsequent displacement. It was early recognised that the drier the dressing the better, and hence anything like a mackintosh layer was carefully avoided. In some instances, antiseptic powders were employed, but they did not find much favour, and because they tended to favour slipping of the dressing, and to prevent the adhesion of the gauze dressing to the wound, they were certainly not desirable when there was any necessity for the patient to travel. In the absence of reliable water the use of antiseptic lotions was obligatory, and such is likely to be the case in most campaigns; in the present one, filtration of the thick muddy water was impossible, without a considerable expenditure of time, which could only be obtained when the hospitals were fairly stationary. I very much preferred carbolic acid lotions.
