174 THE VETERINARY SCIENCE. 



ventilated stable. It is often seen in taking a horse out of a 

 pasture field and giving- him a hard day's work in the sun when 

 he is not used to it. 



Symptoms. — The first symptoms are dullness and dryness of 

 the skin, and if the horse is working he will not be sweating as 

 much as he should ; he will also be noticed not to take his food 

 very well, and have a staggering gait when he is walking. These 

 symptoms may be noticed two or three days before the disease 

 sets in. If he is working he will finally stagger and fall down, he 

 may then struggle for a short time, but, finally, will lie quiet, with 

 complete loss of power and feeling ; if you prick him with a pin or 

 knife he does not feel it, the pupil of the eye is very much enlarged, 

 the pulse quick and weak, he breathes heavy, and when you try to 

 get him up he will not be able to help himself at all. 



Treatment.^Apply cold, wet cloths and ice bags to the head 

 around the brain, and keep these on until he gets relief, and also give 



Sweet Spirits of Nitre 1 ounce or 4 tablespoonfuls. 



Whisky 1 wineglassful. 



Mix in a half pint of cold water and give as a drench. Repeat 



this every hour and a half or two hours until he gets relief. Be 



careful in drenching him while in this state for fear of choking him. 



As well as the above drench give a dose of physic consisting of 



Bitter Aloes 8 to 10 drams. 



Common Soda 1 teaspoonful. 



Ginger 1 " 



Mix in half pint of luke warm water and give as a drench. 

 If the animal seems to take notice to things around him and wants 

 to eat, give him soft food with boiled flaxseed in it, and give 

 plenty of cold water to drink, in small quantities at a time, but 

 often. If the horse lays for any length of time turn him over two 

 or three times every da}, this will prevent his lungs from becom- 

 ing aff'ected, and he will lie easier. Keep the body very warm 

 with plenty of blankets, this will have a tendency to draw the 

 blood away from his head. In this case, as in others, when the 

 animal is down keep plenty of dry bedding under him. As soon 

 as he wants to get up, and seems able, help him to his feet. 



CONCUSSION OF THE BRAIN. 

 Causes. — It generally occurs in a horse when he is running 

 away and strikes his head against something, or in rearing up 

 and falling back and striking the pole of the head. In some cases 

 he gets better quickly, while in other cases he may die very 

 suddenly.
