VIRULENT MANGE. 467 



produced form, but it may be known by its generally attacking 

 young puppies, while the other appears at all ages, but chiefly in 

 the adult animal. The hair falls off in both, but there is more 

 scab in the insect mange, probably from the fact that it does not 

 produce such violent itching, and therefore the scratching is not 

 so incessant. The treatment is nearly the same in both cases, being 

 chiefly by external remedies, though alteratives, stomachics, and 

 tonics, are often required from the loss of health which generally 

 accompanies the disease. In all cases, therefore, it is necessary to 

 attend to this, giving generally a mild aperient first, such as (12) 

 or (13), and subsequently (2) and (3) combined together, or (1) 

 and (59), according to circumstances. At the same time one of 

 the following applications may be tried externally, with the greatest 

 care that the dog does not lick them off, as they are highly poi- 

 sonous when taken into the stomach. To the wash some aloes is 

 added, with the view of preventing this by the bitter taste of the 

 drug, but though it has this good effect partially, there is nothing 

 like a wire or leathern muzzle kept constantly on, except when 

 feeding, at which time of course the tongue is otherwise engaged. 

 All applications must be rubbed well into the roots of the hair. 



Ointment (or dressing) for virulent mange : 



Green iodide of mercury, 2 drachms. 

 Lard, 2 ounces. 



Mix, and.rub as much as can be got rid of in this way into the diseased skin, 

 every other day, for a week ; then wait a week, and dress again. Take care 

 to leave no superfluous ointment. 



A milder ointment : 



Compound sulphur ointment, 4 oz. 

 Spirit of turpentine, 1 ounce. 

 Mix, and rub in every other day.
