Is occasionally prescribed in diarrhoea and flatulence, and mixed 

 with drying powders. 



When administered in gastric flatulence charcoal should be 

 reheated to thoroughly purge it of moisture and gases which it 

 may have absorbed. 



To do this spread it about' y 2 inch thick in a large pan and 

 place it in the oven of a stove with a slow fire, leave it in until 

 the charcoal comes to a dull red color, then put it in a bottle and 

 seal until wanted for use. Its action depends on its power of 

 absorption. 



In these cases it must be given in capsules and in large 

 quantities ; as much as ^2 lb. and occasionally a pound is used.

 powerful antiseptic and parasiticide, more powerful than carbolic 

 acid; it is used pure, in solution or in an ointment in strengths 

 of 1 to 50 to 1 to 20. Used internally, in gastric fermentation, 

 dysentery, typhoid fever and as a vermifuge and locally as an 

 antiseptic. In mange it is used in 5 per cent solution. Glycerin 

 renders it more soluble. For worms give horses one ounce in a 

 quart of water, on an empty stomach.

 as a wash; or, seeds, 1 to 1^ ozs., aqua 1 quart, boil down to
