'Causes'.--Independent of the natural agents before referred to in the production of inflammatory affections, there are some few causes to which we can especially attribute this disease. Direct injuries done to the member itself, either by wounds or stings of insects, the taking of poisonous or irritating substances into the mouth, want of water while hunting in hot weather, &c. Several years ago we witnessed the death of a very valuable pointer, suffering from this disease produced by poison maliciously administered. He was affected so suddenly and violently with inflammation of the throat and tongue that his owner, Mr. F--, was lead to believe that a bone had lodged in the throat, which was the occasion of all the trouble. After proper examination and considerable delay, he was forced to abandon this erroneous idea, but not in time to save the poor animal, who soon died from strangulation or congestion of the lungs. This valuable dog might have been saved if promptly and energetically treated. The stings of wasps or bees may also produce this affection. 'Treatment'.--Nothing can be done with this malady without the use of the lancet, by which six or eight ounces of blood should be drawn at the commencement of the disease. If the tongue is much swollen and very tender, longitudinal incisions should be made in it, extending as far back as possible, and their bleeding assisted by sponging the mouth out with tepid water. Astringent applications may then be used as washes, such as alum water, strong vinegar, infusions of oak bark or solutions of nitrate of silver, four or six grains to the ounce, to be applied once or twice a day. A large blister may also be placed under the throat, and when the inflammation is sufficiently reduced to allow the introduction of articles into the stomach, a powerful purge of aloes should be given. Nothing, however, can be done without copious bleeding.--L.] THE LIPS of the dog discharge, with somewhat less efficiency, the same office as in the horse, cattle, and sheep; and are usefully employed in gathering together the food, and conveying it to the mouth. The lips also secrete the saliva, a fluid that is indispensably necessary for the proper comminution of the food.
