When the disease is established
When the disease is established, the animal is sensitive to cold. It seeks warmth, and is constantly shivering; when taken hold of, it is felt to tremble violently, so much so that the pulse cannot be accurately counted. The bowels are generally constipated. A thick purulent discharge flows from the eyes; and the white around the eye, if the upper lid be retracted, will be seen covered with numerous small and bright red vessels, giving to the part the appearance of acute inflammation. The vessels now spoken of are not to be confounded with the veins which are natural to this organ. These last are large, and of a purple hue, while their course is in the direction of the circumference of the cornea. The small vessels, indicative of distemper, are fine, bright in color, and their course is towards the centre, or in a line directly the opposite to that indicated by the veins. They are never present during health, though they are often to be witnessed in other diseases besides that which is here treated of. A glairy mucus, or yellow fluid, moistens the nostrils, and if the ear be applied to the head, the breathing will be discovered to be accompanied with an unusual sound. The cough is often severe and frequent; it is sometimes spasmodic the fits being almost convulsive, and terminating with the ejection of a small quantity of yellow frothy liquid, which is thrown off by the stomach. The digestion is always impaired, and sickness is not unusual; the matter vomited having an offensive smell, and never being again consumed by the animal, as is generally the case when the creature is in health. The nose is dry and harsh; the coat staring and devoid of gloss: the skin hotter than is customary, and the paws warm. The pulse is perhaps quicker by twenty beats than during the prior stage, but less full the artery feeling sharp, short, and thin under the finger.
