sesthesia abate, and the patient may become once more able to 

 swallow, but an ascending paralysis, beginning in the limbs 

 spreads over the body and death occurs in from one to eighteen 

 hours. In the paralytic stage there may still be slight jerking of 

 the muscles, or tremors, but violent convulsion no longer occurs, 

 and there is extreme prostration, with hurried, rattling breathing, 

 small, weak, irregular pulse and finally, stupor and coma. 



Diagnosis in man. The only additional point, to those already 

 stated for animals, is in regard to lyssophobia. This false form of 

 hydrophobia is usually fortified by the fact of a bite, but as a 

 rule it lacks the exaltation of common sensation and of the special 

 senses which characterizes genuine hydrophobia . Very often also 

 there is a flaw in the history, the dog that inflicted the bite is un- 

 known and may still be alive, in which case no medicine is so 

 good as to bring the healthy dog into the presence of the patient. 

 The dog may have been killed by an excited community without 

 any identification of his symptoms as those of rabies or any post 

 mortem examination to throw light on his case. The attack 

 may have come on after a conversation on the subject of the bite, 

 or of rabies, and perhaps, as in the case of the Montpellier cadet, 

 long after and when the patient had for the first time heard that 

 the dog that bit him had been mad. It may be that rabies does 

 not exist in the district and that no other victim in man nor beast 

 can be adduced. It may be that the patient has a nervous or- 

 ganization or is subject to hysteria, and therefore specially pre- 

 disposed to any disease of the imagination. Such cases cannot 

 be accepted as rabies until a successful inoculation has been made 

 on one or more animals.
