300 INFLAMMATIONS. 



unceasing industry, that dog cannot be too carefully watched, 

 there is great danger about him ; he may, without any other 

 symptom^ be pronounced to be decidedly rabid. I never knew a 

 single mistake about this. 



" Much has been said of the profuse discharge of saliva from 

 the mouth of the rabid dog. It is an undoubted fact that, in 

 this disease, all the glands concerned in the secretion of saliva 

 become increased in bulk and vascularity. The sublingual glands 

 wear an evident character of inflammation ; but it never equals 

 the increased discharge that accompanies epilepsy or nausea. The 

 frothy spume at the corners of the mouth is not for a moment to 

 be comj)ared with that which is evident enough in both of these 

 affections. It is a symptom of short duration, and seldom lasts 

 longer than twelve hours. The stories that are told of the mad 

 dog covered with froth are altogether fabulous. The dog recover- 

 ing from, or attacked by, a fit may be seen in this state ; but not 

 the rabid dog. Fits are often mistaken for rabies, and hence the 

 delusion. 



" The increased secretion of saliva soon passes away. It lessens 

 in quantity ; it becomes thicker, viscid, adhesive, and glutinous. 

 It clings to the corners of the mouth, and probably more annoy- 

 ingly so to the membrane of the fauces. The human being is 

 sadly distressed by it, he forces it out with the greatest violence, 

 or utters the falsely supposed bark of a dog, in his attempts to 

 force it from his mouth. This symptom occurs in the human 

 being when the disease is full}^ established, or at a late period of 

 it. The dog furiously attempts to detach it with his paws.
