CHAP. III. The signes of Impostumes or Tumors in general.
* 1.1BEfore we undertake the cure of Tumors, it is expedient to know their kinds and differences, which knowledge must be drawn from their proper signs, the same way, as in other dis∣eases. But because the proper and principal signs of tumors are drawn from the essence of the part they possess, we must first know the parts, and then consider what their essence and com∣position are.
We are taught both by skill in Anatomy, and the observation of the depraved function, especi∣ally when the affected part is one of those which lie hid in the Body; for we know whether or no, the external parts are affected with a Tumor against Nature, by comparing that with his na∣tural, which is contrary. For comparing the sound part with the diseased, we shall easily judge whether it be swollen, or no.
But because it it not sufficient for a Chirurgeon only to know these general signs (which are known even to the vulgar) he must attentively observe such as are more proper and neer. And these are drawn from the difference of the matter and humors, of which the tumors consist.
* 1.2For this, Galen teaches, That all differences of Tumors arise from the nature and condition of the matter which flows down and generates the tumor; also they are known by such accidents as happen to them, as colour, heat, hardness, softness, pain, tension, resistance.
Wherefore pain, heat, redness, and tension, indicate a sanguine humor; coldness, softness, and no great pain, phlegm; tension, hardness, the livid colour of the part, and a pricking pain by fits, melancholy; and yellowish and pale colour, biting pain without hardness of the part, cho∣ler.
And besides, Impostumes have their periods and exacerbations following the nature and moti∣on of the humors of which they are generated. Wherefore by the motion and fits it will be no dif∣ficult matter to know the kind of the humor; for as in the Spring, so in the morning the blood is in motion; as in the Summer, so in the midst of the day, choler; as in Autumn, so in the even∣ing, Melancholy; as in Winter, so in the night the exacerbation of phlegm are most predomi∣nant. For Hip••••crates and Galen teach, that the year hath circuits of diseases, so that the same pro∣portion of the excess and motion of humors, which is in the four seasons of the year, is also in the four quarters of each day.
Impostumes which are curable have four times: their beginning, encrease, state, and declinati∣on; and we must alter our medicines, according to the variety of these times. We know the be∣ginning by the first swelling of the part; The encrease, when the swelling, pain, and other acci∣dents do manifestly encrease, and enlarge themselves; the state, when the foresaid symptoms in∣crease no more, but each of them, because at their height, remain in their state immoveable, unless the very matter of the tumor degenerate,* 1.3 and change it self into another kind of humor; The declination, when the swelling, pain, feaver, restlesness, are lessened. And from hence the Chi∣rurgeon may presage what the end of the tumor may be; for tumors are commonly terminated four manner of wayes, if so be, that the motion of the humors causing them be not intercepted, or they without some manifest cause, do flow back into the body.
Therefore first they are terminated by insensible transpiration, or resolution; secondly, by suppuration when the matter is digested and ripened; thirdly, by induration, when it degene∣rates
