there are traces of suppuration and of ulceration. The mucous mem- 

 brane of the nose is found studded M'ith small, hemorrhagic spots, 

 sometimes red, more frequently brown or black, often coalesced with 

 each other in irregular sized patches and surrounded by a reddish 

 zone, the product of irritation. If oedema of the intestines has 

 occurred the membrane is found four or five times its normal thick- 

 ness, reddish in color, with hemorrhages on the free surface. CEdema 

 of the lungs leaves these organs distended. On section a yellowish 

 fluid runs out, like the fluid does from lungs which have been filled 

 with Avater in the dissecting room. The secondary alterations vary 

 according to the comijlications. There are frequently the lesions of 

 asphyxia; externally we find ulcers, abscesses, and gangrenous spots 

 and the deep ulcers resulting from the latter. The lymphatic cords 

 and glands are found with all the lesions of lymphangitis. Again 

 are found the traces of excessive emaciation, or the lesions of septi- 

 caemia. Except from the complications the blood is not altered in 

 anasarca. If previous to the attack the animal had renemia the tis- 

 sue will be infiltrated and the pallor and other appearances of aenemia 

 will be found. If prior to the attack the animal is in moderate health, 

 with unaltered blood, the blood will be found to clot with the typical 

 change of the buffy coat of the horse. In death by asphyxia the 

 blood will be found fluid, black in color, but gradually turns red, 

 and clots on exposure to the air. Dieckerhoff mentions fibrinous 

 Ijneumonia among the alterations. I myself have never seen it 

 occur. 



The diagnosis of anasarca must principally be nmde from farcj' or 

 glanders. In anasarca the swelling is nonsensitive, while sensitive 

 in the acute swelling of farcy. The nodes of farcy are distinct and 

 hard and never circumscribed, as in the other disease. The erujjtion 

 of glanders on the mucous membranes is nodular, hard, and pellet- 

 like. The redness disappears on pressure. In case of excessive 

 swelling of the head, in anasarca, there may occur an extensive sero- 

 fibrinous exudation from the mucous membranes of the nose, poured 

 out as a semi-fluid mass or as a cast of the nasal fosste, never having 

 the appearance or tjpical oily character which it has in glanders. 

 The inflammation of the lymphatic cords and glands in anasarca does 

 not produce the hard, indurated character which is found in farcy. 



Sejificanuia may have occurred i^rimarily, or as a complication of 

 anasarca. The diagnosis must be from the history, and the prognosis 

 is of little import. 



While this is not an excessively fatal disease, the i^rognosis must 

 always be guarded. The majority of cases run a simi^le course and 

 terminate favorably at the end of eight or ten days, or possibly after 

 one to two relapses, requiring several weeks for comi)letc recoverj^ 

 Effusion into the head renders the jirognosis much more grave from 

 the possible danger of mechanical asphyxia. Threatened mechanical
