 tonics are indicated. If the stock have been grazed on rape or 

 turnips, they should be gi-\'en plenty of dry food to compensate

Where the symptoms have once manifested themselves, the 

 sheep is almost sure to perish, medical treatment being of no

 the heart, are comparatively empty; the kidneys are pale, the 

 tubules containing a viscid fluid; the liver is enlarged and soft-

 petechiae (spots).

 great debility, and extravasation of blood from the capillaries, 

 the blood itself being altered in character.
