and one part of iodide of potassium, with six to eight parts of water. 

 Williams gives, as an alterative, arsenic of potash ; take arsenious' acid 

 one drachra, carbonate of potash one drachm, water twelve ounce? ; mix 

 and boil slowly until the arsenic is dissolved, and strain when cold, 

 and give from one-half ounce to one ounce of the liquor two or three 

 times a day. 



Sallenders. — This is a kind of squamous inflammation of the skin. 

 It is an eczemous disease. Occurring upon the hock, it may cause 

 falling off of the hair. In some cases irritation is set up from some 

 cause or other, and an aqueous discharge takes place. The irritation 

 ceases to a certain extent, and you have a thickened condition of the 

 skin. This disease is more common in heavy draft horses, especially 

 if highly fed, as stallions which are allowed to run down in winter, 

 and then suddenly fed up in the spring. This has a tendency to pro- 

 duce it ; or it may come from the flies irritating some sore upon the 

 parts. Although not a serious disease, it is difiicult to treat. Blister- 

 ing may produce a well marked case. 



Treatment must be both local and constitutional, and if the owner 

 must work the horse, y u may relieve the irritation by washing once 

 or twice, but do not wash every day, just once or twice, and dress with 

 an alkaline soda solution ; after which you will find benefit from using 

 the remedies already mentioned, or you may use an anodyne oint- 

 ment. Give a purgative, or, if you cannot do this, on account of 

 working, etc., just stint in his allowance of food to a certain extent; 

 give diuretics pretty freely. Proud flesh or granulations may come 

 from flies, etc. In such a case you can use nitrate of silver or butter 

 of antimony, and endeavour to protect the hock as well as possible 

 from the flies. If you can apply a poultice to the hock, do so. A 

 lotion of corrosive sublimate is very good. Corrosive sublimate two 

 drachms, alcohol four ounces, water one pint. It requires careful 

 treatment and it is difficult to effect a cure, especially if the horse is 

 highly fed. There is no specific for it, 



Mallenders is just the same condition of the limb, but attacks the 

 fore-limb on the knee, and is treated just the same way. It may come 

 from getting the foot over the halter. 



Eczema Rubriiin. — In dogs it is not contagious. It is similar to 

 eczema in the horse, the result of too high feeding or want of exer- 

 cise. It comes in hunting dogs, from working in the long, wet, rough 

 grass. 



Symptoms are well marked. He suffers severely, and rubs himself 

 very much. If you examine closely, there will be no parasites. It 

 comes along the belly, shoulders, etc. 



Treatment. — Give a laxative; buckthorn syrup, one, two, or three 

 ounces, according to the size of the dog, is very useful, but be careful 

 in using carbolic acid on dogs, for it will be absorbed, and in many 

 cases poison the dog. However, it is most useful. A small quantity 

 will destroy a dog, by acting upon the nervous system. Change the 

 food, and if he has been allowed too much animal food, change to a 

 bread diet. 



Settle Rash. — The name is taken, perhaps, from the human 

 pathology. Surfeit is another name applied to it, coming from the 

 belief that it comes from faulty feeding ; urticaria is a name applied 

 in many of our works. It is very frequent, and may occur at any 

 season of the year, but most frequently in the spring, and comes very 

 quickly. It consists of elastic pimples of various sizes and shapes 

 coming upon the shoulder, head, neck and body, and in many cases
