PLEURISY PNEUMONIA.

PLEURISY. 



Auscultation and Percussion. Complete 

 absence of the respiratory murmur, with 

 the crepitating wheezing always at the 

 bottom of the chest ; sometimes a gurgling 

 noise. Vesicular respiration very strong 

 in the upper region of the chest, or in the 

 sac opposite to the effusion. 



Continuance of the Effusion. Absence 

 of the respiratory murmur gains the mid- 

 dle region of the chest, following the level 

 of the fluid. These symptoms may be 

 found on only one side ; a circumstance of 

 frequent occurrence in the dog, but rare in 

 other animals. The respiratory murmur 

 increases in the superior region of the 

 chest, or on the side opposite to the effu- 

 sion. Inspiration becomes more and more 

 prolonged. Breath always cold. Cough 

 not existing, or rarely, and always sup- 

 pressed and interrupted. Exercise pro- 

 ducing much difficulty of respiration. 



Resolution, or He-absorption of the ef- 

 fused Fluid, and Organization of false 

 Membrane, the consequence of Pleurisy. 

 Slow but progressive re-appearance of the 

 respiratory murmur, and disappearance of 

 the sounds produced by the fluid. Dimi- 

 nution of the force of the respiratory mur- 

 mur in the superior part of the chest, or of 

 the lung opposite to the sac in which the 

 effusion exists. Gradual return of the 

 respiratory murmur to the inferior part of 

 the chest. Inspiration less deep, and re- 

 turning to its natural state. 



Chronic Pleurisy, with Hydrothorax. 

 Inspiration always deep, expiration short. 

 Cough dry, sometimes with expectoration ; 

 frequent or capricious ; always absence of 

 complete respiratory murmur in the in- 

 ferior portion of the chest. Sometimes 

 the gurgling noise during inspiration and 

 expiration. Strong respiratory murmur 

 in the superior portion. In dogs these 

 symptoms sometimes have existence only 

 on one side of the chest. The mucous 

 membranes are infiltrated; serous infil- 

 tration on the lower part of the chest and 

 belly; sometimes of the scrotum or the 

 inferior extremities ; generally of the fore 

 legs. The animal lies down frequently, 

 and dies of suffocation. 



PNEUMONIA. 



Auscultation and Percussion. Circum- 

 scribed absence of the respiratory murmur, 

 without any determined place, in one 

 point, or in many distinct parts of the 

 lung. The respiratory murmur increased 

 in one or more of the sound parts of the 

 lungs, or in the sound lung if one is in- 

 flamed. 



Passage to a State of Gray Indura- 

 tion. The absence of respiratory mur- 

 mur indicates extensive hepatization of 

 one lung; a circumstance, however, of 

 rare occurrence. When the induration is 

 of both lungs, and equally so, the respi- 

 ratory murmur and the inspiration remain 

 the same, except that they become irregu- 

 lar. The cough dry or humid, frequent, 

 and sometimes varying. Exercise accom- 

 panied by difficulty of respiration, without 

 dyspnoea. 



Resolution or Re- absorption of the 

 Products of Inflammation of the Paren- 

 chymatous Substance of the Lungs. Di- 

 minution of the force of the respiratory 

 murmur in the sound parts. Cessation of 

 the crepitating wheezing. Slow return of 

 the respiratory murmur where it had 

 ceased. Respiration ceases to be irregular 

 or interrupted, and returns slowly to its 

 natural state, or it remains interrupted. 

 This indicates the passage from red to 

 gray induration. 



Chronic Pneumonia (Gray Indura- 

 tion.) Inspiration or expiration inter- 

 rupted. Cough unfrequent ; suppressed ; 

 rarely with expectoration; always inter- 

 rupted. Complete absence of respiratory 

 murmur. 



(Softening of the Induration, Vlcerations, 

 Vomicce, ffc.) Mucous and wheezing ; 

 mucous rale in the bronchial ; discharge 

 from the nostrils of purulent matter, 

 white, gray, or black, and sometimes 

 fetid. Paleness of the mucous mem- 

 branes. The animal seldom lies down, 

 and never long at a time. Death by suf- 

 focation, when the matter proceeding from 

 the vomicae, or abscesses, obstructs the 

 bronchial passages, or by the development 

 of an acute inflammation engrafted upon 

 the chronic one.
