. Special pathology and therapeutics of the diseases of domestic animals. Veterinary medicine. Cutaneous Tuberculin Test. 585 opposite thin fold (Fig. 94). In some animals a small hemorrhage occurs at the point of inoculation. As a rule the overlying epidermis dries up into a brown crust or scab. A swelling appearing immediately after the injection of the tuber- culin but disappearing after a few hours and which, according to Vallee is due to glycerin and salts contained in the tuberculin must not be regarded as a positive reaction. Lignieres as well as Roemer and Joseph inject the tuberculin on the side of the neck and as near as possible to the cutis. In this case a positive reaction consists in the appearance, beginning on the following day, of a painful edematous swelling around the point of Fig. 94. Intradermal Tuberculin Reaction. Edematous swelling of the right anal fold following injection of cc. of 50% tuberculin into the tissue of the cutis. For an objective determination of a reaction the thickness of a fold of skin about 5 cm. wide is accurately measured by means of micrometer calipers immediately before, and then again three or four days after the injection of the tuberculin at that point. If, during that tunc the fold has increased in thickness to the extent of cm. or more, the reaction is to be regarded as positive, if the increase is only to cm. the reaction is to be looked upon as doubtful and the test should be repeated with cc. of concentrated tuberculin applied on the opposite side of the neck. By means of their method ( cc. of 10% tuberculin) Moussu and Mantoux obtained in 70 head of cattle reactions corresponding in all respects.
