“THE taciturn rabies. 
*•' Dumb madness forms the other and most frequent variety in 
adult dogs, and which cases appear dependent on a less degree 
of active censorial excitement, but with greater morbid affection 
of the bowels. The symptoms which succeed to the premoni- 
tary 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 breath¬ 
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 tumefaction. 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 cany 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 is 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 ordinary 
“ * 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 tho 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.”
