The chief symptom noted is the enlargement of the head, which in some cases,becomes twice the normal size. The lips and tissue of the inside of the mouth are muchswollen and if the swollen parts are pressed with the finger nail, the impression 26 remains for a long time. These swellings may become so large in severe cases thatthe animal can not close its mouth. When the disease has advanced, a rusty-coloredfluid runs continuously from the eyes and nose. The eyelids become so swollen thatthe animal cannot keep its eyes open. The lining membrane which covers the lids,the conjunctiva, becomes filled with fluid and causes a bladder-like protrusion. Ifthis swollen membrane is pricked with a needle, the fluid matter contained thereinwill ooze out. Usually there is very little pus to be found in any part of the A case of Big Head. In nearly every case we found that the primary point of infection was in thevicinity of either the upper or lower third premolar tooth. There was usually a trackbetween that tooth and the outside of the bone forming the tooth cavity, but thetooth cavity itself was not always involved. If a probe were introduced into thistrack or fistula, when the upper side of the jaw was affected, it could be pushed upalmost to the eye cavity. In the early stages of the disease, the treatment consists in extracting the teethin the vicinity of the infected cavity, and syringing out the track to remove the 27 accumulated infective material. Good results have been obtained in some early casesby swabbing the cavity with tincture of iodine and applying stimulating linimentsto the swollen parts. After the disease has advanced and the germs have reachedthe blood stream, treatment is very discouraging, and a Jarge percentage of theaffected animals die. We have t
