GENERAL DISEASES. 93 



Dark spots are found on the tliecse of the muscles, and in 

 the muscular tissue in various parts. 



The serous membranes show petechial spots and extrava- 

 sations. The pleura, endocardium, pericardium, and cere- 

 bral and spinal meninges, may all be so affected. The serous 

 cavities themselves often contain a gelatinous coloured exud- 

 ation. The mucous membranes are black or blackish-green. 

 The intestinal membranes frequently present ecchymosis, 

 and much infiltration with exudation. The mesenteric 

 glands are similarly infiltrated; the liver and spleen are 

 congested and friable. The lungs are also usually congested, 

 and the trachea and bronchi filled with dark-coloured frothy 

 extravasation. 



Treatment. — Attend to the sanitary conditions firstly and 

 chiefly. Medicinally, chlorate of potassium and salines, fol- 

 lowed by iron preparations and doses of turpentine, may be 

 administered. 



Astringents are preferred by some ; ergot of rye, tannin, 

 tincture of perchloride of iron, and acetate of lead being 

 especially recommended. 



Antiseptics also are worthy of trial, and the beneficial 

 action of chlorate of potassium may be due to its antiseptic 

 effect. 



If there be much debility, alcohol and vegetable tonics 

 should be given. We have found calcium sulphidej^^ in full 

 doses, of very great value in the treatment of this disease. 



Ammonium salts are to be avoided. 



The diet should be liberal. 



Locally, the sores should be dressed with antiseptic solu- 

 tions. If the head be much swollen, fomentation with warm 

 water is very useful. The swellings should not be punc- 

 tured. 



If there is much dyspnoea from swelling of the mouth or 

 nostrils, tracheotomy may be necessary.
