DISEASES OF DOMESTIC ANIMALS. 205 



cases, be increased' I have used it as strong as one to sixteen, but do 

 not keep up the use of this strong lotion, but after one injection use the 

 weak solution ; give general tonics — iodide of potassium, iodide of iron, 

 etc. Percival recommends acetate of lead, 1 drachm ; opium, 1 scruple : 

 turpentine, 2 ounces. But the best, perhaps, is the iodide of iron, iodide 

 of potassium, etc. In cattle, it is similar, but if it is associated with 

 tubercular disease, the animal will be unfit for breeding purposes. 



Barreiiuess may be due to contraction of the os-uteri. Apply bella- 

 donna, and dilate by means of the fingers and catheters. 



DISEASES OF THE OVARIES. 



Enlargemeuts— Ovarian Tumours are generally of an encysted 

 character. They are more likely to occur in mares that have had several 

 colts, but they may come in any from faulty conformation. 



Symptoms are not very plain. It may exist to a great extent without 

 extending the abdomen. The mare is supposed to have slight attacks of 

 colic, but the symptoms differ from some colic. The pain continues per- 

 haps a half hour or an hour, the pulse is not materially affected, and the 

 symptoms gradually disappear ; the mare is usually irritable, falls off in 

 condition, and may have a tucked up appearance ; the tumour may pass 

 around some of the intestines and cause strangulation — causing the 

 ordinary symptoms of strangulation. If there is slight irritation in con- 

 nection with the generative organs, and these symptoms are present, 

 make an examination fcr rectum, and if it is any great size you can 

 detect it. There may be a slight discharge from the vagina. There can 

 not be much done by way of treatment in the mare. I would recom- 

 mend iodine, iodide of potassium, etc., and you may deem it worth trying 

 an operation, but it is not generally successful. 



Vaginitis is generally the result of difficult parturition. Give a laxa- 

 tive and iodide of potassium, and you may use some slight astringent. 

 Allay the irritation. 



Abscess on the Vulva, caused by some irritation. Open up and let 

 the matter out. If she is in good condition, give a laxative ; if in poor 

 condition, give nutritious food. 



Partial Closure of the Lips of the Vulva, may occur in the cow 

 after difficult parturition. The lips may grow up until you could scarcely 

 introduce the ordinary director. It is best treated by opening up, and, 

 if seen in the early stage, you can do this with the fingers ; then use a 

 pledget of tow to keep the lips from uniting. Allay the irritation ; 

 apply lotions, etc. 



Ovariotomy. — This, like everything else, requires practice. It is 

 frequently performed in pigs, by cutting into the flank on either side, 

 remove the ovaries, secure the vessels and treat as a wound. It is best 

 to get a dead animal and examine as to the position of the ovaries, 

 etc., before operating on a living animal. Cattle are sometimes operated 

 on They take on flesh more rapidly after the operation. It has been, 

 and is still, recommended to splay milk cows four or five months after 

 calving, and it is said that they will give milk for four or five years and 

 take less food. It was advocated in Scotland some twenty-five years ago, 

 but I think it proved a failure. But lately it has been practiced and 

 recommended, especially in the southern part of the United States. 

 One way of operating is to cut into either side, the same as in the pig.
