This operation appears to cause formidable injuries, the abdominal tunic and the muscles of the flat portion of the thigh being largely exposed, but in reality the wound is less grave than might be supposed, and healing occurs in a comparatively short time, provided none of the diseased tissue is left.

The dressing is renewed at intervals of two or three days, and when cicatrisation proceeds regularly it may be omitted and replaced by antiseptic irrigation.

In the ewe and she-goat the operative technique is identical:

First stage. Elliptical incision, including the teat.

Second stage. Breaking through of the intermammary connective tissue partition and the subcutaneous tissue. Ligature of the anterior mammary vein.

Third stage. Isolation of the mamma from the front backwards. Ligature of the vessels of supply. Extirpation.

Fourth stage. Suture and drainage.
