Which prevents the two diseases from appearing exactly the same

In its character, distemper approaches very near to "continued fever" in the human subject; the chief difference being consequent upon the more delicate constitution and more irritable temperament of the dog, which prevents the two diseases from appearing exactly the same. It consists in a general fever, which produces a morbid excitement of all the mucous membranes. The digestive track is the principal seat of the disease, but of course its presence is most easily recognised at those parts which are most exposed to view. Thus the membrane of the eye, being a comparatively large surface, and by its delicacy well calculated to denote every variation of the system, is usually the first observed, and often the only place inspected. If this be cloudy or watery, the nature of the malady is at once concluded; the membrane of the nose also, though less palpable, is under observation; and if its secretion be copious and opaque, the fact is generally imagined to be established. The alterations, however, exhibited by these membranes are no more than sympathetic derangements, they being continuous with the more important organs; and when proofs are found in the eyes or nose, the disorder is generally confirmed, or has taken hold of the system. Some have supposed the disease originated in the nose, and thence extended to other parts; now I shall not stop here to consider so groundless an hypothesis. It essentially is fever affecting the entire of the mucous surfaces, but especially those of the alimentary canal.
