or both lungs may be af- 

 fected, or only a part of 

 one, or all of one lung. If 

 the ear is placed on the 

 chest duringthe first stage, 

 engorgement of the affected 

 part with blood and bloody 

 serum is noticed, and a 

 characteristic crepitation is 

 heard, like the sound pro- 

 duced by rubbing the hair 

 between the fingers, near 

 the ear. As solidification occurs, this sound disappears, but in the 

 part of the lung unaffected there is an exaggerated murmur, while 

 none at all is noted in the solidified part, The boundaries of this 

 may be mapped out by percussion, or striking over the chest, from 

 the flat, dull sound produced. The pulse becomes rapid, small, and 

 feeble, breathing more labored, and shorter ; cough is occasional and 



weak. The animal now 

 stands as in Fig. 995, 

 with back and nose out- 

 stretched. If the head 

 is raised quickly, there 

 is great tendency to fall 

 backward. (Fig. 996.) 

 Gradual prostration and 

 wasting follow, and at 

 length the animal drops 

 head foremost — first fall- 

 ing upon the chest — (Fig. 997), with legs doubled beneath, and next 

 upon the side, where she remains,' occasionally lifting the, head and 

 vainly attempting to rise,, under great distress, until death termi- 

 nates her Suffering. Pneumonia may also terminate in resolution 

 of the consolidated lung, or abcess and gangrene. 



Treatment. — Clothe and house the patient, according to the 

 season of the year, but freely allow pure air ; give an enema of hot 

 soap-suds, or a saline laxative in a pint of gruel : — 



Epsom salts 8 to 12 oz. 



Gentian and ginger (powdered) each, 1 " 



Bleeding at the very outset is recommended by some reliable 

 authorities, in plethoric animals with high inflammatory symptoms, 

 and quick, full, bounding pulse. Later give sedatives : — •
