THE DISEASES OF CATTLE. 43 



is no blood to spare. In the next place blood under all the 

 stages of this malady is highly carbonized. Now it seems to 

 be more necessary to decarbonize it than to abstract it ; it 

 can be decarbonized by administering repeated doses of am- 

 monia with much better prospects of success, than by the former 

 process. 



Ammonia is always indicated in debilitating diseases, and in 

 congestions of the lungs ; it stimulates the circulatory apparatus 

 to increased activity, and thus induces a more equal distribu- 

 tion of the blood ; in this way congestions are relieved. 



The dose of aqua ammonia, as a diffusable stimulant, de- 

 carbonizer and antiseptic, is from two to four drachms ; it 

 should be largely diluted with water or gruel, for if given alone 

 it will act as a vesicant and irritant, and thus do more harm 

 than good. It may be given often, provided it is well diluted, 

 as it does not accumulate in the system, but is generally ex- 

 creted from the same through the common excretory outlets. 



Ungent symptoms may be thus relieved, for example : 

 should the animal have a bad cough, a dram of Tilden's or 

 Thayer's fluid extract of lobelia may be given occasionally, in 

 a draught of water, and after the exhibition of ammonia, should 

 the pulse indicate a sedative, half an ounce of powdered nitre, 

 may be given at intervals of two hours until the pulse become 

 softer and less frequent. 



The best purgative should such an agent be indicated, is 

 chloride of sodium, — common salt. Dose, eight or twelve 

 ounces dissolved in water. 



Should the animal be feverish, which may be discovered by 

 the unnatural heat of the external surface, dry state of the 

 mouth, accompanied by excessive thirst, scanty urine, etc., a 

 few doses of the solution of the acetate of ammonia mjiy be 

 given. Dose, three ounces diluted with water. 



INOCULATION FOR CONTAGIOUS PLEURO-PNEUxMONIA. 



It appears, from reports made by French and German veter- 

 inary surgeons, that inoculation for the above disease must 

 come into general practice, and finally will prove of great
