 The result of the examination will be found farther on. 



It is very difficult to point out the diagnostic symptoms of pneu- 

 monia to th" non-professional observer, as we ascertain its ejctent, 

 its situation, and every step of its progress, by means of the ear. 

 All the symptoms that give us the most sure information respect- 

 ing the nature of the disease, the event to which it tends, and the 

 remedial treatment which it requires, spring out of the actual 

 changes wrought in the pulmonary substance itself; and these 

 changes are disclosed to us by the method gf auscultation. It is 

 Vecessary, therefore, in order to treat this disease understandingly 

 and properly, you should know first of all, what those changes are 

 which are produced by inflammation of the substance of the lungs : 

 that you should know the morbid anatomy of pneumonia, as an 

 indispensable groundwork for the knowledge of its pathology. 

 For this reason, if none other, the account of the autopsy given 

 would be valuable in order to grasp more fully the rationale of 

 treatment. 



The majority of cases of simple pneumonia in dogs, is allowed 

 usually to run its course unnoticed, no symptoms being observed 

 other than a slight cough, or comparative dull condition of the 

 animal ; or it passes for a very slight attack of distemper, and runs 

 its usual course terminating favorably, thanks to the constitution 

 of the animal, and not the so-called distemper remedies. But if 

 the simple imflammation of the lungs involves the surrounding 

 tissues, as may be the case from the outset, or as a result of pneu- 

 monia proper, it becomes an entirely different affair. The pleura, 

 (the serous membrane that lines the interior of the thorax,) is 

 most likely to be involved, and the disease becomes pleuro-pneu- 

 monia. 



Autopsy of a Newfoundland bitch, aged thirteen months. 

 Examination six hours after death : 



The intemjri changes were confined almost entirely to the 

 chest. On opening this, the animal being placed on the back, we 

 found layers of yellowish, friable, false membrane, varying in tena- 

 city, stretched across and around the sack containing the heart. 

 Adhesions of this character existed on both sides of the chest, and 

 ivere bathed in a yellowish grumous fluid or serum, which proved
