S20 ANNUAL REPORT OF THE Off. Doo. 



tive LTj, which has been likened to that of a dog fatigued in the 

 chase, and in succeeding short barks which may follow, the jaws 

 do not close completely as in ordinary barking. 



While this symptom is a striking one and quite constant, it may 

 be lacking at times and certain dogs remain quiet in spite of all at- 

 tempts to excite barking. The appetite diminishes about this time; 

 food is taken with njore or less difficulty, and soon it is refused, 

 swallowing having become painful and difficult. The animal may 

 appear to have a bone stuck in its throat, a symptom which often 

 tempts the owner to make the dangerous examination for some 

 obstruction. There is no fear of water, and the animal drinks water 

 and other liquids quite greedily, until paralysis of the constrictor 

 muscles of the pharynx makes swallowing impossible. 



The excitation becomes marked and the animal is now furious. 

 If a stick or other article is presented to him he seizes it with 

 power; he attacks the bars of his cage or any object in the cage. If 

 at liberty, he attacks every object in his way, swallowing all sorts 

 of articles, such as wood, paper, straw and stones, the presence of 

 which in the stomach after death is one of the most striking features 

 of the disease. At this time he begins to wander, running with his 

 tail hung, the mouth open and the eyes with a wild look; he at- 

 tacks every object or animal which comes in his path. As a rule, 

 he runs straight ahead and does not turn out of his way to at- 

 tack animals. The dog may travel tremendous distances, but is 

 apt to return to his home, exhausted and covered with dust and 

 blood, or else he may continue his course until he falls exhausted, 

 as much as fifty miles being covered. Very soon paralysis sets in, 

 cojnmenciug in the hind legs, and finally becomes general. The 

 dog is no longer able to stand; the weakness becomes more marked 

 and stupor sets in, from which the animal may be aroused, but 

 which becomes deeper and deeper, and ends in death. The course 

 of the disease is always rapid, covering from six to ten days, and 

 averaging from four to five days. The symptoms are so character- 

 istic that once seen can scarcely be mistaken for any other disease. 

 The furious t^pe just described is the most common. 



Paralytic Form, The paralytic type, ordinarily spoken of as 

 "dumb rabies," constitutes from 15 to 20 per cent, of all cases. In 

 certain countries, as in Turkey, it is the prevailing type, which ex- 

 plains the relative rarity of rabies in man in this country where 

 dogs abound. The commencement of the disease is the same as 

 in the furious type, but the accesses of fury are lacking. For sev- 

 eral days the dog appears restless, seeking seclusion and dark places. 

 The paralysis may commence in various parts of the body, but, as 

 a rule, affects first the muscles of the jaw, which soon drop, the 

 dog being unable to close its mouth, and the tongue hanging out;
