DISEASES OF THE NERVOUS SYSTEM. 263 



head low and stretched out, nostrils dilated, superficial veins 

 distended, eyes protruded and red, pupils contracted, breathing 

 rapid and wheezing or deep and stertorous, the pulse quick 

 and weak, and the heart-beats tumultuous. This is followed 

 by prostration, a state of unconsciousness, palsy or convulsions 

 and death. If recovery ensues it is followed by dulness, un- 

 certain movements of the limbs, drowsiness, or other signs of 

 brain disease. 



Treatment. — Douche the head and neck with cold water, and 

 make the same application to the whole body, unless the weak- 

 ness of the patient forbids this. Throw stimulating injections 

 into the rectum (ammonia or oil of turpentine and oil. If the con- 

 vulsions are aggravated by the douche use injections of chloral- 

 hydrate instead. Apply frictions and mustard embrocations to 

 the limbs and the sides of the neck, especially when uncon- 

 sciousness and coma come on. Improvement may be expectec^ 

 when the pupils dilate, and above all when consciousness 

 returns. A failing pulse should be met with stimulants by the 

 mouth and rectum. To prevent sun-stroke much may be done 

 by keeping in vigorous health, avoiding ill-aired stables, using 

 breast-straps in place of collars, and wearing a sunshade and a 

 small wet sponge on the top of the head.
