These are cases that occur in any part of the body indifferently: the rest have certain seats, which I am going to speak of, beginning with those in the head. In this a great number and variety of tubercles rise, called ganglia[ GQ ] melicerides[ GR ], atheromata[ GS ]; there are some other kinds, to which authors give different names; to which I shall also add steatomata[ GT ]: which though they often arise in the neck, and in the armpits, and sides, I have not mentioned separately; since all of them differ but little, and neither are threatening, nor require any different treatment from each other. Now all these rise from a very small beginning, and increase gradually for a long time, and are inclosed each in a coat of its own. Some of them are hard, and resist pressure, others are soft and yielding; some of them are bald in a part, others remain covered with hair, and are commonly without pain. What their contents are, though it may be pretty well guessed at, yet cannot be certainly known, till they be taken out. However, generally in these that resist, there are found either some stony substance, or a number of hairs concreted together: but in those that yield, something resembling honey, or thin pulticula, or the scrapings of cartilage, or insensible or bloody flesh; and these are commonly of different colours. And for the most part ganglia are elastic: the atheroma contains a liquor like thin pulticula: the meliceris a more liquid one, which therefore fluctuates upon being pressed: there is a fat substance in the steatoma, and that generally has the largest circumference, and so relaxes the whole surface of the skin above it, as to make it slide backward and forward; whereas, in the rest, it is more bound. It is proper first to shave them all if they be covered with hair, and then to cut them through the middle, that whatever was collected within may be evacuated. But the coat of the steatoma must also be cut; because it is not easily separated from the skin and subjacent flesh. In the others the coat is to be preserved entire: and immediately, when it appears white and tense, it must be separated by the handle of the knife from the skin and flesh, and taken out together with its contents. If, however, it should happen, that the lower side of the coat adheres to a muscle, lest that be wounded, the upper side must be taken away, and the lower left in its place. When the whole is extracted, the lips must be brought together, and a fibula put upon them, and over that an agglutinating medicine. When either the whole coat, or any part of it is left behind, medicines to promote a digestion must be applied.
