junctiva yellow. Eczematous or pustular eruptions may appear 

 on the skin on the nose, lips, neck, back, loins, croup or 

 perineum. 



Lesions. In addition to the lesions described above, there are 

 usually gastro-intestinal inflammation, oedema of the peritoneum 

 and pleura, in the lung as well as in the serosae, (pneumonia is 

 not uncommon especially in sheep), intestines, kidneys and mus- 

 cles, hsemorrhagic spots are not uncommon, the blood forms a 

 loose black coagulum, and the encephalon is ansemic and 

 softened. 



Treatment. The first consideration is to cut off the supply of 

 mercury. Mercurial applications on the skin should be washed 

 off with tepid water and if necessary soap. An application of 

 sulphide of potassium will precipitate the mercury in an insolu- 

 ble form. For mercurial agents in the alimentary canal an 

 emetic may be given (if the animal is one susceptible to emesis) 

 followed by a saline laxative. This may be combined with or 

 followed by raw eggs, mucilage, wheat gluten or other albumin- 

 oid, sulphide of potash or sulphur, to precipitate the mercury 

 and prevent its absorption. Later, when the bowels have been 

 cleared, iodide of potassium in small doses will serve to dissolve 

 and remove what mercury may be lodged in the tissues. 



Locally one of the best applications is chlorate of potash as a 

 mouth wash, 2 drs. to the quart of water. To this may be 

 added tannic acid or other vegetable astringent and even alcohol. 



Finally a course of iron and bitter tonics will serve a good 

 purpose in restoring the general tone.
