DISEASES FOLLOWING PAETUKITION. 231 



(9) If in 2 hours the cow is not 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 scrupulous and 

 rigid precautions as at first. In all cases, but especinlly in severe 

 ones, it is well to keep watch of the patient, and to repeat the dis- 

 tention 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 the treatment may be repeated if necessary. 



Accessory treatment may still be used, but is rarely necessary. A 

 dose of purgative medicine (l^} pounds of 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 slrin to stimulate 

 the movements of the bowels. Sponging the sldn^ and especially 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 nearly 22,000,000 milch cows. If we 

 could raise their quality by preserving and breeding from the largest 

 producers of both milk and butter fat, in place of losing the best by 

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

 increase of 2 quarts a day, the proceeds at 3 cents a quart would 

 amount to $130,000,000 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 caused by low condition, weak- 

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

 of the hind limbs by a large calf passing through the pelvis. Its 

 symptoms do not differ from those of palsy of the hind limbs, occur- 

 ring at other times, and it may be treated in the same way, except so 

 far as bruises of the vagina may demand special smoothing treat- 

 ment. 



CONGESTION OP THE UDDER (GARGET). 



In heavy milkers, before and just after calving, it is the rule that 

 the mammary gland is enlarged, hot, tense, and tender, and that a 

 slight exudation or pasty swelling extends forward from the gland 

 on the lower surface of the abdomen. This physiological congestion 

 is looked upon as a matter of course, and disappears in two or three 

 days when the secretion of milk has been fully established. This
