"the taciturn rabies. 



'• Diitnh madness forms tlie other and most frequent variety in 

 adult dogs, and wliich cases appear dependent on a less degree 

 of active censorial excitement, but with greater morbid affection 

 of the bowels. Tlie symptoms which succeed to the premoni- 

 tai-y ones, are often rapid ; and superadded to the dull, heavy, 

 and distressed countenance, costiveness, &c., there appears a 

 stiffness about the jaws, and a hollow sound is emitted in bi-eath- 

 ing, which is rather performed by the mouth than the nose, that 

 being plugged up with pus, or the arch of communication being 

 straightened by tumefacti(m. As the whole of the pharynx and 

 larynx becomes tumefied to the full extent, the muscles at the 

 base of the tongue, and those of the lower jaw are rendered 

 inert; the mouth remains open, and the tongue hangs pendulous 

 without; and sometimes there exists an actual inability to close 

 the jaws. A congestion of blood is the necessary consequence 

 of the distention of the parts, and the tongue from this cause 

 usually appears, in these cases, livid or almost black, particu- 

 larly towards its apex or point : frequently a black central line 

 extends through its whole length. This state of the parts occa- 

 sions often a difficulty, sometimes a total inability even, to swal- 

 low either liquids or solids. In general, however, the inability 

 is principally confined to liquids, which are, in such instances, 

 returned as fast as they are lapped, from the incapacity of the 

 tongue to carry it into the pharynx ; but in no instance, as al- 

 ready insisted on, do the attempts to swallow appear to excite 

 apprehension or give pain. The mouth itself is mostly parched 

 and dry ; occasionally, however, it is seen with saliva continu 

 ally flowing from it.* It ts the tumefaction of the pharynx that 

 produces the deep choking noise already noticed, and which 

 seems to issue from the bottom of the glottis : all the oi'dinary 



" * In most cases, an increased salivary flow arises at some period of the 

 complaint, which is not frequently lasting-, but is succeeded by a viscid bronchial 

 secretion, that appears to irritate the dog beyond endurance ; and to remove 

 which he often employs himself with the utmost violence, in forcing his paws 

 against his mouth, as dogs do when a bone is lodged between the teeth."
