PNEUMONIA INFLAMMATION OF THE SUBSTANCE 



OF THE LUNGS. 



THIS disease is frequent in certain climates in all our domes- 

 tic animals. Its causes are similar to those already referred 

 to under the heads ' Laryngitis/ ' Pulmonary Congestion/ and 

 ' Bronchitis.' Contrasted with the latter disease, it will pro- 

 bably be found that pneumonia occurs more frequently in 

 young and vigorous animals, than bronchitis, especially of a 

 relapsing form.
