Peuch and Cruzel recommend friction with oil of cade. Repeated cauterisation with nitric acid is declared to give good results by destroying the new tissue.

These modes of treatment, however, are impracticable in dealing with large multiple lesions, nor does the elastic ligature give much better results.

Total removal with the scissors or bistoury, or simply tearing out by hand, is preferable to any other course. Troublesome bleeding may follow, but is rarely of great importance. It usually stops in a few minutes, even where small arteries of the size of several millimètres in diameter have been divided. As a measure of precaution, however, the little wounds may be touched with the red-hot blade of the thermo-cautery.

The écraseur is rarely required. The smaller warts are generally sessile, and can be removed with a bistoury or a sharp curette. The removal of those about the udder requires considerable precaution to avoid injuring the teats.

All the growths are usually removed at one operation; Moussu has thus taken away 30 lbs. weight without the slightest ill effect. After the wounds have been washed with an antiseptic, the raw surfaces are powdered with a mixture of equal parts of boric acid, tannin, and calcined alum; cicatrisation occurs in a few days.

URTICARIA IN THE PIG.

This disease usually attacks pigs during the spring or summer, producing characteristic cutaneous lesions, which, however, are of a benign character. It seems to arise from some form of alimentary intoxication.

Symptoms. At first the dominant symptoms point to disturbance of digestion. The appetite is lost, and the bowels may be confined or there may be diarrhœa. This is sometimes accompanied by vomiting, and by fever.
