“ The intervening time between the inoculation by the rabid 
bite, and the appearance of the consequent disease, is very vari¬ 
able in all the subjects of it: in the majority of instances, the 
effects appear in the dog between the third and seventh week. 
Cases, however, do now and then occur, where they have been 
protracted to three, four, or even a greater number of months. 
Although, therefore, caution should not be lost sight of, even 
after eight weeks have elapsed, yet the danger may be consi¬ 
dered as inconsiderable after that time. A week is the shortest 
period I have met with between the bite and rabid appearances. 
Mr. Youatt never saw a case with less than seventeen interven¬ 
ing days. In the horse, as far as my own experience goes, the 
average time is the same with the dog; Mr. Youatt, however, 
hints at one after four months. In cattle, the probatory period 
seems much the same as in horses and dogs. In the human, it 
may appear in a month, or be protracted to three or four; and 
the late Mr. Henry Earle authenticates a case within his own 
knowledge, in which the hydrophobic symptoms were delayed 
until a twelvemonth after the bite. Of the extraordinary in¬ 
stances we read of, which have been protracted to five, twelve, 
and even nineteen years, I do not believe one. 
“symptoms of rabies. 
“I shall now proceed to describe the pathognomonic and 
occasional indications of the rabid malady, premising that the 
varieties in both, but particularly in the latter, are so numerous, 
that hardly any two cases present themselves under a directly 
similar aspect. It is, however, certain that, by the aid of the 
pathognomonic symptoms, the disease may be commonly de¬ 
tected without fear of mistake. The extent of the former, and 
the necessity for a distinct notice of all the varieties of the lat¬ 
ter, render a perspicuous account of the malady extremely diffi¬ 
cult, and necessarily extend it beyond the limits of a summary. 
“ Rabies sometimes commences with dulness, at others with a
