The duration of this mild form has been observed to last for two months, 

 though it usually terminates in about two weeks. 



The benignant form in the stallion is not so well marked as in the mare, 

 though, if carefully observed, there will be noticed evident and irritable 

 swelling of the prepuce (sheath), extending in some instances to the yard, 

 causing more or less collapsus of it, and like the benign form in the mare, 

 will sometimes disappear without causing any severe lesion, though this 

 favorable termination cannot always be depended upon, for often, from want 

 of attention, or other cause it develops into the malignant form. 



The malignant form of the disease in the mare is much to be dreaded, for 

 its onset and course are frequently so aggravating as to cause the most dis- 

 tressing symptoms, and death in the end. 



It is ushered in with the same general symptoms as are exhibited in the 

 benign form, but soon we have a strong smelling catarrh from the mucous 

 membrane of the vagina. On the outside of the vulva, as well as upon the 

 delicate skin of the thighs, and under the tail, will be found circular abrasions. 

 The emission of urine gives rise to much irritation, even amounting to 

 excitement. The animal becomes hide bound, and swellings appear in various 

 parts of the body — circular in outline, and say a couple of inches in diam- 

 eter. They disappear after a time, to however, make their appearance in 

 some other part. 



Then we have frequently nervous complications to contend with, producing 

 in some animals a degree of marasmus hideous to behold. 



The animal, if required to walk, will do so in a very uncertain manner, 

 showing that, to a great extent, it has lost control of its joints, which 

 indeed may be much tumified. Things keep going from bad to worse, until 

 death eventually closes th-e scene. 



The malignant form in the stallion is often a sequel to the benignant, and is, 

 therefore, ushered in with the same characteristic symptoms. The yard and 

 other contiguous parts will be marked with abrasions similar to those of the 

 mare. The act of urination causes pain, showing that the lining of the 

 urethra must be involved. The animal will soon begin to lose condition and 

 become weak. If required to walk or trot, will govern himself is a very 

 awkward manner, swaying from side to side, and sometimes falling. Other 

 general symptoms are so like those of the mare that they do not require 

 description. 



The malignant form of the disorder may extend through a period of months 

 or even years before it will have run its course. 



SANITARY MEASURES TO BE ADOPTED FOR THE PREVENTION OF AN 



OUTBREAK. 



I may say in connection with the disease under consideration that preven- 

 tion is not only better, but more easily accomplished than cure, by abstain- 

 ing from the importation of mares or stallions for breeding purposes, from 

 infected districts. When the disease prevails in a State or territory, all stal- 

 lions used for breeding purposes, should be carefully examined by a competent 

 person every now and again, and the slightest symptoms dealt with accord- 

 ingly. 



Of the treatment of this complaint I am sorry to say it has not been very 

 satisfactory up to the present, that is, when the disease manifests itself in
