 result in injury to the horse as well as to the driver

Treatment. As the sllitack rarely lasts over a few min- 

 utes, nothing is needed in the line of treatment that can 

 be of service during the attack. The veterinarian, if 

 called, never arrives in time to witness an attack. It can 

 do no harm to endeavor to prevent the recurrence of 

 attacks by the use of alterative and tonic treatment, 

 although it is extremely doubtful whether any form of 

 treatment would accomplish this. It usually suffices to 

 assure the client that the attacks are not serious and that 

 they will eventually subside altogether. 



The development of a somewhat nervous disposition 

 is an occasional sequel of vertigo in young horses. 

 Whether this is a direct effect of the disease, or merely 

 apprehension psychosis, I am not able to say.
