DISEASES OF THE RESPIRATORY ORGANS. 41 



tory murmur in those portions not diseased, and as the 

 malady proceeds this murmur becomes quite obliterated, the 

 crepitus general and more defined, and the other symptoms 

 all increased in severity. 



. If the malady is not checked at this stage, it quickly 

 passes on into the second. The crepitus on auscultation is 

 absent, and no sound, except it be a slight wheezing or 

 whistling noise, can be detected ; hepatization has then taken 

 place, and inflation is but a'cipher. The sound emitted on 

 percussion at this stage is very characteristic of consolidation, 

 being flat and dead. 



The cough now is frequent, and accompanied with red or 

 rusty expectoration ; the eyes have a sunken appearances ; 

 respiration is performed with great effort and pain ; the 

 cheeks are inflated in the act, nostrils dilated and the general 

 expression is haggard and pitiful in the extreme. The posi- 

 tion on the haunches is still maintained, or if changed, it is 

 but momentarily to stand with the fore-legs propped apart to 

 allow more room for the abdominal muscles to aid respira- 

 tion. 



When the third stage arrives and suppuration commences 

 — in other words, when the lung structure breaks down, aus- 

 cultation discovers a new sound — a bubbling or gurgling 

 crepitation caused by the passage of air through pus. 



On placing the hand flat upon the side, much the same 

 sensation will be communicated ; it is as though fluid was 

 boiling underneath, and I have been painfully struck with 

 this phenomenon both in the human and canine subject. The 

 appealing look for relief in this stage is most affecting ; 

 acutely is the weakness of human aid now felt by the atten- 

 dant — petting, caressing, words of comfort and pity, are all 

 that he has to dispose of. 



The cough is now loose, and accompanied with copious 

 expectoration ; the mouth and lips are coated with sticky 

 slime ; the breath has a peculiar foetid, cadaverous odor, and 

 is taken in short gasps ; the ears and extremities are cold
