Are very common in the dog, and consist of small soft bags, lying close under the skin, of a circular form, and devoid of pain or inflammation. They vary in size from that of a pea to the volume of a small orange. The only remedy is the knife, which may be used with perfect safety, by anyone accustomed to it. The skin must be saved and dissected back, and the tumour, when exposed, may readily be lifted out of its bed without much dissection; after which the parts may be suffered to heal of themselves.
