SYMPTOMS 87 
phlegm are brought into the mouth and evacuated or 
swallowed; vomiting sometimes accompanies the violent 
efforts to dislodge this phlegm. 
Gentle squeezing of the larynx from the outside will 
easily induce a fit of coughing; therefore, except for 
purposes of diagnosis, it should not be indulged in. It is 
not long before the catarrhal process extends down the 
trachea to the bronchi, and eventually to the bronchioles. 
(3) Bronchitis—Bronchitis manifests itself by a slight 
respiratory acceleration, perhaps (but not constantly) an 
increased temperature, and rhonchial sounds on auscul- 
tation. If the sma:] bronchi become implicated, resulting 
in a condition known as capillary bronchitis, there is a 
further frequency of respiratory movement, greater 
difficulty in getting breath, and an obstinacy on the part 
of the animal to move, such movement usually accentua- 
“ting the cough and distressing the dog. Auscultation 
will now reveal dry or moist rd/es, the former in the 
earlier stages, due to the presence of viscid secretion in 
the bronchial tubes, or a thickening of their walls, and 
the sound produced has a whistling, musical, or squeaking 
quality ; the moist rd/es are in evidence so soon as the 
secretion becomes liquid, and one hears crackling, 
crepitant, or bubbly sounds. | 
(4) Broncho-pneumonia.—If at this stage the patient has 
become, or was previously, weak and unable to expel the 
accumulations of bronchial secretion, a further and serious 
complication arises, which doubtless accounts for many 
deaths in distemper. Owing to the bronchioles be- 
coming clogged with muco-purulent exudate, consoli- 
dated patches in single lobes are formed, which may 
extend to larger areas. This condition is known as 
catarrhal or broncho-pneumonia. Its onset is marked 
usually by a considerable rise in temperature, great 
dyspnoea, rapidity of pulse and respirations, feeble but
