apparently cured of it, and with a perfectly healthy skin, produce 

 a litter of whelps all of which broke out with mange at four or 

 five months old, though scattered in various parts of the country 

 at their walks ; the bitch afterwards showing the impurity of her 

 blood by again and again becoming the subject of mange. I should 

 therefore never breed from either a dog or bitch who was attacked 

 by this form of eruption. There is considerable thickening of the 

 skin with an ofiensive discharge from the surface, chiefly flowing 

 from the cracks and ulcerations under the scabs on it. This dries 

 and falls ofi" in scales, taking with them a good deal of the hair, 

 which is further removed by the constant scratching of the poor 

 dog, who is tormented with incessant itching. Almost alwaj^s 

 there is a fat unwieldy state of the system from want of exercise, 

 but the appetite is often deficient. The treatment is founded upon 

 the constitutional nature of the disease, which is not caused by any 

 parasite or vegetable growth, and is solely the result of what is com- 

 monly called foulness of the blood. The first thing to be done is 

 to clear out the bowels by a brisk aperient, such as (12) or (13). 

 Then give low diet without flesh, starving the dog till he is ready 

 to eat potatoes and green vegetables, alternately with oatmeal 

 porridge, — and then only in moderate quantities. As soon as the 

 stomach is brought down to this kind of food, but not before, begin 

 to give the liquor arsenicalis with the food, the dose being a drop 

 to each four pounds in weight of the animal, and thus a dog of 

 eight pounds' weight will require two drops three times daily ; 

 taking care to divide the food into three equal portions, and not 

 to give more of this altogether than is required for the purpose of
