DISEASES OF THE BLOOD. 31 



finement or to destroy hard objects. In the early stages 

 there is profuse salivation, but this does not last longer 

 than a couple of days ; a small amount of froth may collect 

 at the angles of the mouth, and the patient endeavours to 

 remove it by rubbing with the paws. The animal-in such 

 cases is generally, supposed to have a bone in the throat, 

 a report which must be always looked upon with the 

 greatest suspicion as probably dumb rabies. Only in the 

 earliest stages is vomition present, and a small amount of 

 blood may be expelled ; later there is paralysis of the 

 alimentary canal, as indicated by obstinate constipation and 

 the tendency of foreign bodies to accumulate in the 

 pharynx and stomach. Such foreign matters as straws, 

 sticks, and hair are picked up by the dog in the earliest 

 stages of the disorder, when there is perverted appetite as 

 indicated by appreciation of anything cold to the tongue 

 when licked, by tendency to eat dung, either his own or 

 that of other dogs, horses, &c, also to lap urine (which is 

 considered very diagnostic). As paralysis of the throat 

 sets in, the ingested matters are retained at the back of 

 the mouth against or in the pharynx. Male dogs are most 

 often affected, probably because there are more of them, 

 and hot on account of any special sexual features, or 

 deprivation of opportunity for sexual gratification simul- 

 taneously with high excitement, as was at one time sup- 

 posed. It has been observed, but not proved, that when 

 a pregnant female has been bitten, any active manifesta- 

 tion of the effects of inoculation is reserved until after 

 parturition has taken place, then the bitch may for a time 

 perform well her duties as a mother, but it is possible, 

 although not proved, that she may convey the disease to 

 her offspring in her milk. Fever is present in rabies, and 

 in the more advanced stages there is a hollow sound in 

 breathing, which act is especially performed through the 

 nose. The eye of the mad dog is at times abnormally 

 bright and red, and may present a certain amount of stra- 

 bismus, which gives the animal an excessively sinister 

 appearance ; in other cases (especially of the dumb form of 

 the disease) the eyes are dull, sad, and heavy looking, and,
