be active, or it will be of no avail. Large bleedings, followed by 

 a calomel purge (12), and the fever powder (50), will be necessary ; 

 but no time should be lost in calling in skilful aid, if the dog's life 

 is valued. 



Chronic laryngitis attacks the same part, comes on insidiously, 

 and manifests itself chiefly in a hoarse cough and stridulous bark. 

 It is best treated by a scton in the throat, together with low diet 

 and the alterative pill (1). 



Bronchocele is known by an enlargement, often to the size of the 

 fist, of the thyroid body placed on each side of the wind pipe. If 

 this does not press upon the air-passage, there is no inconvenience ; 

 but in course of time it generally does this, and the dog becomes 

 wheezy and short-winded. It is chiefly seen in house pets, and 

 may be relieved by the internal use of iodine (3), given for weeks 

 in succession. 



INFLAMMATION OF THE LUNGS. 



The organs of respiration consist of an external serous and an 

 internal mucous membrane, united together by cellular tissue. 

 Each of these is the seat of a peculiar inflammation (pleurisy, 

 pneumonia, and bronchitis), attended by different symptoms and 

 requiring a variation in treatment. There is likewise, as in all 

 other inflammations, an acute and a chronic kind, so that here we 

 have six different inflammatory disorders of the organs of the 

 chest, besides heart disease and phthisis or consumption. All the 

 acute forms are attended with severe sympathetic fever, and quick 

 pulse ; but the character of the latter varies a good deal. The 

 chronic forms have also some slight febrile symptoms; but gener- 

 ally in proportion to the acuteness is the amount of this attendant 

 or sympathetic fever. As these three forms are liable to be easily 

 mistaken for each other, I place the symptoms of each in juxtapo- 

 sition in the following Table :
