Observe. If the collar is not too tight on the neck, interfering 

 with the free passage of air in and out of the windpipe. 



Causes. Generally from some thickening of the glands of the 

 neck, or of the windpipe — the effects of bronchitis or distemper, 

 not treated, or improperly treated, in not supporting the strength; 

 whereby all thickenings are taken up, or reduced and even pre- 

 vented.

Gunshot Wound. — This is, excepting in times of war, a rare 

 occurrence, and the treatment consists in extracting the bullet, and 

 healing the wound as for an ordinary sore. The bullet is ex-

 grasps the bullet, and extracts the ball.

(5.) Inflammation of the heart. 



(6.) Ossification of tlie heart.

 breathing, nor yet from its depth, but from a peculiar double beat 

 or hitch, differing from all other varieties of breathing, either of 

 fever, inflammation, or debility,
