I. IT is called in Greek, 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉. in Latin, Oedema; and in English, Oedema, and, the White-swelling. 'Tis true, Hippocrates and other ancient Physicians, under the name of Oedema understood all other Turnors whatsoever; because it signifies an eminency, rising up, or swelling: but those of later times understand only one certain kind of swelling, which is the White-swelling here in∣tended.
II. Definition. Tumor est praeter Naturam, ab Humore seroso aut pituitoso ortum habens, albus, mollis, laxus, indolens, & caloris expers; prementi Digito cedens, & per congestionem frequentiùs, quàm per affluxum Humorum pro∣ductus. It is a Tumor besides Nature, arising from a serous or pituitous matter, white, soft, loose, without pain, and void of heat; yielding to the Fingers being prest, and oftner caused by conge∣stion, than fluxion, or a flux of Humors.
III. The Kinds. It is perfect, when it proceeds from Phlegm only: imperfect, when it pro∣ceeds from other Humors; as Blood, Choler, Melancholy; whence they are called Oedema Phlegmonoodes, Erysipelatoodes, Scirrhoodes.
IV. The Cause. It is caused from Phlegm alone sometimes, and sometimes from a mixtion of other Humors, as is mentioned in the Kinds. But Barbett thinks it to be produced from the ill disposition of the Lympha∣ducts.
V. Galen, ad Glauc. lib. 2. cap. 3. saith, that it is caused by a Pituitous matter; or else by the Spirits, when they are full of Vapors. But by that great Man's leave, tho' in the similar Parts there may be some kind of flatulent Spirit collected, which may tumify the Part; yet this Tumor is not properly Oedema, but rather 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, or 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, a Windy Tumor: of which hereafter.
VI. Sennertus says it proceeds from a serous Humor abounding in the Body, and descending upon the Part, and there abiding and sticking fast, as in a substance more cold than other parts of the Body.
VII. The Conjoined Cause is Phle••m contained in the Blood,
