Dissolve in a pint of lukewarm water and give as a 
drench. If this does not give relief in one hour, give: 
Raw Linseed Oil 1 teacupful. 
Spirits of Turpentine Ya ounce or 1 dessertspoonful. 
Mix and give as a drench. If this does not give relief in 
two hours, follow with : 
Sweet Spirits of Nitre.. , .J^ ounce or 2 dessertspoonfuls. 
Bicarbonate of Soda 1 teaspoonful. 
Ginger 1 teaspoonful. 
Mix in a half pint of lukewarm water and give as a 
drench every two hours until it gets relief. 
In very urgent cases when the life of the sheep is 
endangered it may be necessary to resort to tapping. This 
operation is performed as follows: Select a point half way 
between the point of the hip and the last rib, about three 
inches down from the backbone. Clip the wool from this 
spot, making a bare space about the size of your hand. Cut 
a small hole in the skin just large enough to admit the 
entrance of the trocar and cannula — that used for tapping 
cattle will do. When the instrument has been disinfected 
and oiled press it through the incision, downward and inward 
until it enters the paunch. While the cannula is held in 
position pull out the trocar. The gas immediately escapes 
through the hole thus formed, and saves the sheep's life by 
so doing. When the gas has escaped remove the cannula 
and allow the incision to heal. 
Should a trocar and cannula not be on hand use a pen- 
knife to make an opening and allow the gas to escape. 
4. Impaction of the First Part of the Stomach. 
The stomach of a ruminant is fully described in Part III. 
Notice that the first division merely acts as a sort of store- 
house for food hurriedly taken into the stomach to be after- 
ward fully masticated. In a young. ruminant this division of 
the stomach is comparatively small, but develops as the 
animal leaves its milk diet for ordinary food. It frequently 
happens that the food taken into this division becomes hard- 
ened and packed into a sort of mass to such an extent that it 
does not pass to the next division to be prepared by being 
rolled into balls and forced again to the mouth for re- 
mastication.
