390 ENZOOTIC PARAPLEGIA. 



seized, require nothin<^^ further to ensure their recovery than 

 a complete change of dietary. Many animals I have seen 

 receive no further treatment than removal from the pasture 

 where they Avere grazing to another of a different character — 

 a change from rye-grass ripening its seed to old land and 

 natural grasses not seeding — and this change has been suffi- 

 cient to ensure recovery. 



In addition to the complete change of dietary, it will in all 

 cases expedite the cure if a smart dose of purgative medicine 

 is given whenever this change is undertaken. When this 

 medicine is administered it will of course be necessary to 

 remove the animal to the stable if in the field ; while if green, 

 succulent food, of a character different from what he has been 

 receiving, cannot be obtained, good hay, with a few steamed 

 oats and bran, will do equally well. 



When it is determined that the horse shall be returned to 

 the field if removed from there, care must be exercised that 

 he is not again under conditions as to food-supply similar to 

 those from which he has been taken. 



In young and vigorous animals some recommend the em- 

 ployment of blood-letting as being likely to relieve the more 

 urgent symptoms. 



From what I have observed in cases of cerebral disturbance 

 associated with or resulting from simple indigestion, or im- 

 pacted stomach, where coma, amaurosis, and stertorous breath- 

 ing are present, this may with confidence be carried out. In 

 these it may be observed that the breathing becomes tranquil, 

 and consciousness returns gradually but steadily, and keeping 

 pace with the abstraction of the blood. Here, however, in 

 enzootic paraplegia, where there is rarely unconsciousness, or 

 at least very trifling indication of the cerebral structures being- 

 involved, instead of being beneficial, blood-letting is likely to 

 be followed by undesirable results. Should the bowels not in 

 due time respond to the medicine given, unless the symptoms 

 are becoming aggravated, it is better to wait for tAvo or three 

 days before another dose is administered. A free action of the 

 boAvels is, hoAvever, above all things to be desired, for by this 

 channel avo remove materials Avhich, if retained, Avill certainly 

 further intensify the disturbance. Having secured a moist 

 condition of the canal, it is advisable to keep it in this state
