 clear sign of the absence of this disease ; bnt this opinion is 30 

 entirely in opposition to the careful accounts given by all those 

 who have witnessed the disease when it had unquestionably been 

 communicated either to man or to some of the lower animals, that 

 no reliance ought to be placed upon it, especially where so im- 

 portant a stake is involved. Mr. Youatt witnessed more cases of 

 rabies than perhaps any equally good observer ever did, and be

 times when he is more than usually salacious, may, and does 

 diligently search the urining places ; he may even at those periods 

 be seen to lick the spot which another has just wetted : hut, if a 

 peculiar eagerness accompanies this strange employment, if, in

 unceasing industry, that dog cannot be too carefully watched, 

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

 symptom, be pronounced to he 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

 become increased in bulk and vascularity. The sublingual glands 

 wear an evident character of inflammation : but it never equals

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