are probably due to the animal scratching or gnawing the sore. 

 This is the only skin eruption that characterizes this disease, and 

 it dries up very quickly, so that in from eight to fourteen days we 

 see no other marks except those light, granulating spots (exan- 

 thema of distemper, distemper-pox). Hertwig and Friedberger 

 have observed some cases in which this eruption made its appear- 

 ance without any other symptom of distemper. 



2. Symptoms Indicated by the Eyes. There is generally more or 

 less purulent catarrhal coniuncti%'itis. The animal avoids the 

 light. There are redness and swelling of the conjunctiva. In the 

 early stages the secretion is serous and very fluid. Later on it 

 becomes a muco-purulent secretion, either light gray or yellowish 

 in color. This sometimes occurs in large masses (blennorrhoea of 

 the eyes). This fluid collects in the corner of the lower eyelid 

 or trickles down over the face, drying in yellowish crusts in the 

 edges and borders of the eyelids, frequently gluing them together. 

 The corrosive action of these secretions and also the inflammation 

 of the surrounding membranes may cause lesions of the cornea, 

 sometimes from the animal scratching and rubbiug the eye, espec' ally 

 in animals with prominent eyes (such as pugs and king charles 

 spaniels). In some cases it may be due to deficieut nutrition of 

 the cornea. This ulceration starts with a slight swelling on the 

 external surface of the cornea and subsequent formation of an 

 ulceration. (Other details will be found in the chapter on Diseases 

 of the Eye.) 



AVe see in rare cases keratitis parenchymatosa by extension of 

 the inflammation of the cornea. This may be complicated with a 

 permanent opacity of the sclerotic membrane, and in rare cases the 

 whole eye becomes acutely inflamed and breaks down (see Diseases 

 of the Eye). 



3. Symptoms of the Respiratory Apparatus. These are generally 

 a catarrhal inflammation of the mucous membranes of, the upper 

 air-passages, and, if the disease is acute, the finer sections of the 

 bronchi become inflamed. The first symptom is a catarrh of the 

 nose, which is marked by sneezing and the animal rubbing or 

 Aviping his nose with his front paws. This discharge increases. 

 In the early stages it is simply serous ; later it becomes mucous,
