They often occur in cases of compound fracture, the ends of the broken bones wish their numerous open blood channels presenting the most favorable opportunity for absorption. The occurrence of pyaemia or aeptaemia is indicated by fever, the pulse being small, quick, and irregular. Delirium and stupor are often present. Severe chills, followed by fever and profuse sweating, with extreme depression, are also present. If the wound is discharging, the matter changes from the natural creamy color and consistency, to a bloody or dark thin fluid The skin about the wound becomes bluish or purple, healing ceases, and the wound gaps open. The joints are affected with rheumatic pains, sometimes abscesses forming in them. Breathing is difficult and increased in frequency.

Pyaemia occurs in connection with other conditions, as well as in fracture. Whenever it occurs, from whatever cause, the wound from which absorption takes place should be thoroughly disinfected by washing with carbolic acid alone, or a solution of permanganate of potash. The sick-room should be thoroughly ventilated. Disinfections should bo thoroughly used for the purpose of disinfecting the discharges from the body.
