116 DISEASES OF THE LUNGS. 



racter as to require on our part a great deal of search and 

 inquiry into the case to make them out. The horse is evi- 

 dently unwell^ and yet, to common observation, no particular 

 ailment is demonstrable. There may be no perceptible 

 heaving of the flanks; but little quickness of pulse; no 

 manifestation of pain ; and yet the horse mopes about, dull 

 and dejected; fastidious in his appetite; seldom or never 

 lying down ; looking unkind in his coat ; and out of health 

 altogether in his general appearance. Watch his nostrils : 

 in some of these cases I have found disturbed respiration to 

 be detectible in their movements when I could gain no 

 information from the flanks. At the beginning we must 

 inquire about cough, and examine the nostrils narrowly, to 

 ascertain if there be any expectoration from them. 



Diagnosis. — Such symptoms as these will be sufiicient 

 to direct our attention to the chest as the seat of disease : now 

 that we have percussion and auscultation, however, we need 

 not stop inquiry here, but avail ourselves of their valuable 

 aid to confirm our diagnosis, and afford us further informa- 

 tion as to the particular seat and nature of the morbid action 

 and alterations going on. 



Terminations. — Chronic, the same as sub-acute inflam- 

 mation, is to be viewed as a disorganisiug or destructive 

 process, though it be of a tardy and tedious nature. It 

 may end in hepatization or induration of the substance of 

 the lungs : it is very apt, indeed, to run on to produce 

 tubercles and vomicse, and in this form bring the case under 

 the denomination of what is commonly called phthisis, or 

 " pulmonary consumption/^ 



The treatment to be pursued in these obscure, latent, 

 insidious chronic forms of pneumonia, is to be substantially 

 the same as that recommended for the sub-acute stage; 

 such points as there may be of difference will best come 

 under consideration in treating our next subject, viz. —
