AMMONIUM CHLORIDE 149 



Uses. — The indications for tlie administration of ammo- 

 nium carbonate are much the same as those for ammonia 

 preparations. It ia a more useful expectorant, however, and 

 it and the aromatic spirit are more serviceable in the treat- 

 ment of flatulence. For the latter condition in horses with 

 colic a ball containing ammonium carbonate 3 ii., and cap- 

 sicum 3 i., with sufficient linseed meal and molasses to make 

 the proper bulk and consistency, is often efficient. We may 

 use ammonium carbonate alone in the case of acute or 

 chronic bronchitis, or it may be combined with other 

 stimulants, or expectorants, as ammonium chloride. In 

 electric shock, so common an accident in the larger cities 

 from "live" wires, the administration of full doses of 

 aromatic spirit diluted with half a pint of water will prove 

 a most effective heart stimulant when the animal can 

 swallow.

Action Internal. — ^When ingested, sal ammoniac is a feeble 

 heart and respiratory stimulant, and is not comparable to the 

 ammonia compounds or ammonium carbonate in this respect, 

 it is eliminated in great part unchanged by the urine, but 

 also by the other channels. In its excretion it stimulates 

 the mucous membranes, increases their secretions generally,
