IN PNEUMONIA, the symptoms differ from Pleurisy, yet the difference manifests itself in this, that in _Pleurisy_ there is more pain, and in _Pneumonia_ more difficult breathing. Pneumonia is often a consequence of a cold, bronchitis, or the termination of some disease of the air-passages, and may begin with symptoms of a cold—rough coat, want of appetite, low spirits, etc. In other cases, it begins with a shivering chill; the legs, ears and skin are cold; the coat is rough; the nose pale and dry; quick pulse, which afterwards becomes frequent and full; breathing at first quick, then panting and heaving; the skin now becomes hot, except _the legs, which remain very cold_. This is a _characteristic symptom and will never deceive_; the nose and eyes are red; mouth hot and dry; the eyes have a yellowish color, and the horse looks uneasy and restless. As the disease extends, the breathing becomes more difficult, and is attended with heaving of the flanks; the nostrils are much widened; the nose and head held out; the neck lengthened; the forelegs are fixed in one place, and spread apart; the nose and eyes have a dark blueish color; the face looks anxious and disturbed; _the legs_ and ears are _very cold_; the legs seem fine, and the hair upon them glossy; the cough is more frequent, hard and painful; the horse seems drowsy; there is no appetite; the dung is hard and covered with slime, and the urine high-colored and scanty. In the last stage, the pulse is small, weak, and can scarcely be felt, the breathing is quicker and more difficult; the breath is very hot; the eyes and nose are lead colored; the skin is cold, and clammy sweat breaks out upon it here and there; the mouth is cold; the tongue is coated; the teeth are ground every now and then, and twitches are occasionally seen. The eyes become more and more heavy, glassy and dim; the strength becomes less and less; the horse leans against the stall or manger, or wanders around; he staggers and falls; tries to rise, but cannot; groans, struggles and dies. As an improvement takes place, the horse appears more natural, warmth returns to his extremities, his breathing is more free, pulse softer, fuller and less frequent, cough easier, _and he lies down_ quietly, and without uneasiness. These good symptoms rarely or never deceive.
