    with which it comes in contact; or coagulable lymph oozes from the capillaries and concretes, forming what are called FALSE MEMBRANES sometimes blocking up the passages of mucous surfaces ; and this same exudation On SEROUS SURFACES causes ADHESIONS; sometimes the capillary exhalants are so altered as to allow blood to ooze from them, which fact it is necessary to remember to account for the appearance of blood where no rup- ture of any blood vessel has taken place, as happens 1 in HGMORRAGE from the bowels or other parts. | When a part receives a blow of sufficient force there is an extravasation from the capillary arteries of blood, or of lymph, which causes swelling of the part, but is in process of time absorbed and carried off by the lym- - phatics. In this instance healthy capillaries are compelled by force to allow their contents to escape, which are gradu- ally taken out of the way by the absorbents; in disease the process is similar, in erysipelas, lymph and serum are effused, causing swelling which is gradually ab- sorbed as the patient recovers; in dropsy nearly the same takes place. Blows are frequently of more serious consequence than just stated; if very severe the life of the part may be destroyed, and the dead animal matter becoming fluid by decomposition is removed by the absorbents, in other words an ULCERATION takes place and the _ part will be gradually repaired by granulations. - Sometimes Tumours are formed in consequence of blows, coagulable lymph being effused which becomes by a process similar to granulation vascular and orga- nised (possessed of vitality) a part of the animal, and
