then greasing the parts and letting it go for two or three 
days until it heals, then washing it off with lukewarm water 
and soap and blistering again as before mentioned.

meal and raw linseed oil, obtained from flax seed. 
Action and Use. — Raw linseed oil is given as a very mild 
physic, or what is called a laxative. The dose of the oil is 
one pint poured down as a drench. In all cases, after giving 
it to a horse or cow, allow them to stand in the stable the 
next day and feed light for a few days. Linseed meal is used 
mostly, when given internally, for fattening cattle and for 
animals recovering from weakening diseases. The flax seed

poultices, and is one of the best that can be had. It should 
always be mixed with boiling water.
