502 DOGS USED FOR SPORT. 



tissue, accounts for the cavernous sounds that may be sometimes 

 detected in these diseases, and also for the intolerable fetor of the 

 breath so often present, and for the discharges from the nose, 

 matter being forced by coughing into the posterior portions of the 

 throat, and there lodged, finding its way out through the nostrils 

 by the attempts of the animal to expel it ; besides the nasal passa- 

 ges become diseased through sympathy, and contact with the 

 morbific matter thrown off during exhalation. 



The air passages were found coated with patches of false mem- 

 brane, and bathed in purulent matter throughout their entire 

 length. 



The heart was contracted and pale, containing a little very 

 dark semi-fluid blood in both the left auricle and ventricle. The 

 pericardium (heart's sack), was slightly thickened by deposiU 

 around it, and contained a. slight excess of serum. 



The brain presented no abnormal characteristics. There was

 ratus. The tissues generally were bloodless. 



I know not whether I have made this intelligible to the general 

 reader or not : at all events it may be of some value to my profes- 

 sional brethren, no small number of whom are ardent sportsmen. 



Although difiBcult to instruct the uninitiated in the manner of 

 making a diagnosis, it must be attempted. We first inquire 

 what signals of its existence inflammation holds out ; and how far 

 we, not having the power of seeing what is going on within the 

 cavity of the chest, may nevertheless ascertain the important pro- 

 cesses which are there transacted. 



If the ear be appUed to the chest, and the portion of lung adja- 

 cent to that surface happen to be in the first stage of inflammation, 

 you hear a peculiar crackling sound ; the smallest and finest pos- 

 sible kind of crepitation, which has been happily illustrated by 

 saying that it resembles the multitudinous little crackling explosions 

 made by salt when it is scattered over red hot coals ; another re- 

 semblance is, like the rumpling of a very fine piece of parchment, 

 or like the sound produced by rubbing a lock of your hair between 

 four thumb and finger close to the ear. This is the crepitation or
