further believe that every time we resort to the actual cautery, for the correction of a lameness in an articulation, we admit, in the fact that we do so resort, that we do not fully understand the condition we are attempting to cure. This belief is the result of actual contact with ample clinical material and the observations made in actual practice covering a period of time extending over more than fifteen years. Other chronic pathological conditions, in which iodine applications are frequently serviceable, are various new-growths in the integument, underlying tissues, and in the glandular tissue near the body surface. It is often possible to accomplish, with topical iodine applications, results in these conditions which could only be equalled by surgical interference of much more costly and dangerous character. Iodine applications are at times resorted to in such conditions as these, to obviate the scar formation that might result from a surgical operation. At other times, resort is had to iodine on account of such objections to surgical interference as cost, danger to the patient’s life, protracted period of convalescence, or other equally reasonable objections. In the effects that are obtained from the local applications of iodine preparations, in chronic pathological conditions, these preparations act not only in a palliative or ameliorative sense, but literally in a curative manner. They accomplish, in these conditions, solely and wholly through their own activity, the removal of the condition and the correction of the respective abnormalities. While, in some of the conditions under discussion, the desired result is attained only after very prolonged treatment with iodine, the condition is usually of such a character that neither the owner of the animal nor the attending veterinarian is averse to lending the time consumed. In other of these conditions, the desired result comes very promptly, at times with a rapidity that causes astonishment. In all cases yielding to topical iodine therapy, sufficient evidence of the beneficial effect derived is discernible with sufficient promptness to encourage the continuance of the treatment. IV. The Selection of Iodine Preparations for Practical Use. Next in importance to the proper selection of cases amenable to topical iodine application, is the selection of the particular preparation of iodine to be applied. As I have already pointed out, in the chapter on the general consideration of local iodine therapy, what may be an indication for the use of iodine in one form may lack the requisite pathological status for its successful application in another.
