Enteric oedema. — The effusion on the exterior may take another 

 course and pass to the intestine, causing symptoms of colic, which 

 either ends fatally or more rarely terminates b}^ a profuse diarrhea, 

 which is sometimes hemorrhagic in character. 



P.ulmonary (Edema. — Marked dyspnoea, without swelling of the 

 head, is indicative of metastasis into the parenchyma of the lungs, 

 which will rapidly show dullness on percussion and tubular murmurs 

 on auscultation. The tumefaction leaves the exterior and attacks 

 the lungs, and the animal dies of asphyxia. 



SepticcEmia. — There is certainly no disease in veterinary practice 

 which offers a more favorable field for the development of septicreniia. 

 The large mass of colloid matter held at the temj^erature of the animal 

 body could not be surpassed in the gelatine tube of bacteriological 

 laboratory as a nutriment for the putrefactive ferments. Septicaemia 

 is ushered in by general rigor, sudden elevation of temperature, and 

 marked symptoms of coma. 



TERMINATIONS. 



Resolution. — The simple form of the disease most frequently termi- 

 nates favorably on the eighth or tenth day by absorption of the effusion, 

 with usually a profuse diuresis, and with or Avithout diarrhea. The 

 appetite remains good or is at times capricious. The surface of the 

 body is dirty from desquamated eiiithelium, and at times there is a 

 complete loss of hair, giving the appearance of a bad case of sarcoptic 

 mange. At other times the absorption is slow, lasting for some weeks 

 with tendency to relapses. Again there may be left some permanent 

 induration, the result of embryonic growth. 



Death. — Death may occur from mechanical asphyxia, produced by 

 closure of the nostrils or closure of the glottis. Metastasis to the lungs 

 is almost invariably fatal, causing death by asphyxia. Metastatis to 

 the intestines may cause death from pain, enteritis, or hemorrhage. 



Excessive suppuration, lyrtipliangitis, and gangrene are causes of a 

 fatal termination by exhaustion. Mortal exhaustion is again pro- 

 duced by inability to swallow in cases of excessive swelling of the head. 



Peritonitis may rise secondary to the enteric oedema, or by perfora- 

 tion of the stomach or intestines by a gangrenous spot. 



Sepjtic(B77i'ia terminates fatally with its usual train of symptoms. 



The essential alterations of anasarca are exceedingly simple; the 

 capillaries are dilated, the lymphatic spaces between the fibers of 

 the connective tissue are filled with serum, and the coagulable por- 

 tion of the blood presents a yellowish or citrine mass, jelly-like in 

 consistency, which has stretched out the tissue like the meshes of a 

 sponge. Where the effusion has occurred between the muscles, as in 

 the head, these are found dissected and separated from each other 

 like those of a hog's head by the masses of fat. The surface of the 

 skin is desquamated and frequently denuded of the hair. Frequently
