132 INFLAMMATION OF THE INTESTINES. 



of which one may be given night and morning ; increasing the dose 

 if it occasions no disturbance in the system. Mr. Youatt has, I 

 believe, found benefit in asthmatic cases from the exhibition of 

 prussic acid: but the powerful nature of this remedy requires 

 professional assistance when it is administered. 



INFLAMMATION OF THE PLEURA IN DOGS (PLEURITIS). 



Pleurisy, although not very common in dogs, is yet sufficiently 

 so to deserve our notice. Mr. Youatt observes, that " he scarcely 

 recollects a case of chest afi'ection which did not ultimately become 

 connected with, or terminated in, pleurisy. This disease shews 

 itself by the extreme tenderness of the sides ; by almost constant 

 twitchings, accompanied with suppressed painful cough, which the 

 dog bears with much impatience." He also assures us that an ex- 

 ploration of the chest by auscultation is usually very satisfactory 

 in pleuritic cases. He places the dog alternately on his chest, his 

 back, or his side, which enables him to ascertain to a certainty the 

 extent to which effusion exists in the thoracic cavity. Here too, 

 I am sorry to say, that paracentesis has rarely succeeded, and pro- 

 bably its failure is in some measure to be attributed to the late 

 period at which it was attempted. The mode of treatment differs 

 little from that of pneumonia. In several cases, however, when I 

 have been assured of incipient hydrothorax, balls composed of di- 

 gitalis, tartrate of iron, and a small portion of calomel, have caused 

 the speedy absorption of the fluid." See Veterinarian, vol. vi, 

 p. 294.

INFLAMMATION OF THE STOMACH (GASTRITIS.) 



The stomach is less frequently affected with idiopathic inflam- 

 mation than the bowels ; it is, however, now and then the seat of 

 primary inflammation, and it often becomes affected when the
