ness of the pulse, which is increased to perhaps loo beats per 

 minute ; tumultuous heart's action, the impulse of which is 

 strongly felt behind the left elbow ; a more laborious working of 

 the flanks ; frequent despondent looking toward the flanks ; paw-

 permanent coldness of the extremities ; hanging head with great 

 dullness and despondency of expression ; dull, sunken, lusterless 

 eye ; hanging lower lip ; leaden hue of the nasal mucous mem-

Subacute Pneumonia. This term is employed to designate 

 that subdued or milder form of the disease which sometimes 

 arises independently and at others follows the acute. 



In this variety the characteristic symptoms may be much less 

 marked and the disease is less easily recognized. There is some 

 acceleration and quickness of pulse, lifting of the flanks and heat 

 of the mouth and body generally. There are alternations of 

 heat and cold of the surface and extremities, a rough, unthrifty 

 coat, hide-bound, a dull, listless moping manner and the same 

 symptoms on auscultation and percussion as in the acute form. 



The changes take place slowly, but the disease may prove ob- 

 stinate and is often followed by permanent alterations in the 

 lungs. Rheumatic affections of the limbs, inflammation of the 

 feet, and other diseases frequently supervene during the course 

 of this form of the affection. 



The terminations of pneumonia are : By death ; resolution 

 with absorption of exuded products ; splenisation ; abscess ; 

 gangrene ; permanent consolidation with organization of 

 exuded products. The disease will sometimes lapse into the 

 chronic form. 



Death is fortunately the least frequent issue. It may follow on 

 rapidly advancing and general congestion of the lung — asphyxia ; 

 from heart failure, the overworked organ becoming exhausted 

 under the strain of forcing the blood through the virtually imper- 

 vious lungs ; from hyperthermia, the limit of bodily temperature 

 io8° F. having been reached or exceeded ; or from collapse or 

 exhaustion. 



In resolution which is the most favorable termination the
