DISEASES FOLLOWIXG PAETUEITIOX. 237 



broad tape is tied around the free end of the teat to prevent escape of 

 the air. 



(7) The teat tube, which has been carefully preserved from possible 

 contact with other bodies, is dipped in the creolin solution and in- 

 serted in a second teat, and the second quarter is inflated, and so with 

 the third and fourth. 



(8) The recumbent cow is kept resting on her breast bone, with the 

 head elevated, even if it should be necessary to pack her around with 

 straw bundles or to suspend the head by a halter. Lying on her side, 

 she is liable to develop fatal bloating and to have belching of gas 

 and liquids, which, passing down the windpipe, cause fatal broncho- 

 pneumonia. 



(9) If in 2 hours the cow has not got on her feet, if there is no 

 brighter or more intelligent expression, if she has passed no manure 

 or urine, and if the air has become absorbed, leaving the udder less 

 tense, the injection of the bag may be repeated, under the same scru- 

 pulous and rigid precautions as at first. In all cases, but especially 

 in severe ones, it is well to keep watch of the patient, and repeat the 

 distention on the first indication of relapse. Should there not be a 

 free discharge of feces and urine after rising, indicating a natural 

 resumption of the nervous functions, the case should be all the more 

 carefully watched, so that tlie treatment may be repeated if necessary. 



Accessory treatment may still be employed, but is rarely necessary. 

 A dose of purgative medicine (1^ pounds Epsom salt) in warm 

 water may be given in the early stages, while as yet there is no danger 

 of its passing into the lungs through paralysis of the throat. Eserin 

 or pilocarpin (1^ grains) may be given under the skin to stimulate 

 the movements of the bowels. Sponging of the skin, and especially 

 of the udder, with cool water may be resorted to in hot weather. 



Bloating may demand puncture of the paunch, in the left flank, 

 with a cannula and trocar, the evacuation of the gas, and the intro- 

 duction through the tube of a tablespoonful of strong liquid ammonia 

 in a quart of cold water or other antiferment. 



The economic value of the new treatment of milk fever is enor- 

 mous. The United States has over 16,000,000 milch cows. If we 

 could raise the quality of these by presening and propagating the 

 highest, heaviest, and richest milkers, in place of losing the best by 

 milk fever, as in the past, and if we could thus secure an average 

 increase of 10 quarts a day, the proceeds at 1^ cents a quart would 

 reach $250,000,000 a year. ' 



PALSY AFTER CALVING (DROPPING AFTER CALVING ) . 



This consists in a more or less complete loss of control of the hind 

 limbs occurring after calving, and due either to low condition, weak- 

 ness, and exposure to cold or to injurious compression of the nerves
