398 HYSTERIA. 



Aloes were administered to commence with ; after which I gave 

 the animal Pepsine regularly for some time, after every meal. 

 Eegulation of the diet was strictly enforced. The patient 

 recovered. 



Diet. — The diet of every horse affected with Megrims 

 should undergo a thorough examination and revision. Is the 

 corn fusty ? Is the hay good ? or does it contain dust ? or is 

 it mouldy ? 



Tor every information respecting the diet of the patient, 

 see Section YI., page 108. 



HYSTERIA. 



I now enter upon the consideration of a malady which, up 

 to the present period, has not been described by any English 

 veterinarian except the author of the present treatise. I 

 designate the disease in question Hysteria, from the general 

 resemblance which I believe exists between it and certain forms 

 of Hysteria which at times are known to affect the female 

 species of the genus homo. 



In the year 1854 I published a pamphlet upon this disease,* 

 and up to the period named I have seen and treated six cases 

 of the malady ; since then, however, I have treated four others, 

 and been consulted twice respecting it. 



I have never known this disorder to affect animals of any 

 kind but mares. 



It is far from being a common disease — in proof of which 

 I may state, that I have conversed respecting it with veterinary 

 surgeons who have been forty years in extensive practice, and 

 who have stated to me that they never saw a case of the kind. 



I am unable at present to assign any cause of the disease 



which appears to me adequate to produce it.
