Harpooning the udder according to Ostertag. The operation may be performed on the standing animal, but bet- ter results can be obtained if the animal is cast and secured. Wash the field of operation with soap and water, rinse with 2 per cent, lysol solution, following this with 50 per cent, alcohol. With hooked forceps grasp the skin overlying the suspicious area in the udder and at the fold thus pro- duced incise the skin and underlying facia with scissors, grasp the tissues with the thumb and index finger of the left hand and insert the harpoon with the right. When the suspected tissue has been reached give the harpoon a half turn and withdraw it quickly. The cutaneous wound is closed with artery forceps which are allowed to remain ten minutes, whereupon the wound is sealed with iodoformcollodion. Cows thus treated will give bloody milk for a few days, but if carefully performed the operation is not dangerous. Tubercles, if contained in tissue thus removed, can usual- ly be recognized with the aid of a simple lens. If the exam- ination gives negative results it is advisable to repeat the op- eration. Tubercle bacilli can always be demonstrated in the tubercles. In this method a positive diagnosis alone is of any value. We can not rely upon negative results. This method is o*L.
