months. These, in many cases, have a septic tendency. Parturient 

 bronchitis in the cow is usually of a sub-acute nature, the animal drops 

 off feeding and chewing the cud, secretion of milk is nearl}^ suspended, 

 the flesh falls off very quickly, the animal has a languid appearance, 

 and there is a painful, sore cough, yet the breathing is not much 

 disturbed. While the parturient pneumonia is of a more acute character, 

 the symptoms are somewhat similar, only the cough is not so 

 frequent or so painful, and, on appl3'ing the ear to the side of the 

 chest, the lungs are heard to have a peculiar, jerky, squeaky sound, 

 while the breathing is also much quicker, and abdominal. The 

 following Treatment answers well in both cases: — Put the animal into 

 a good loose box, and apply mustard and water, mixed to the thickness 

 of cream, behind the shoulders for about i6 inches broad, (extending 

 from the spine down to the breast bone), and over this place a piece 

 of newspaper, covering with a sheet and girth. Also give five ounce 

 doses of linseed oil, once a day, following this up, every eight hours, 

 with a dose of half-a-drachm of carbolic acid (B.P.), and half-an-ounce 

 glycerine, in milk or water, tempting the appetite with an3'thing that 

 the animal will eat, and giving to it good nursing. 



535. The most formidable of all chest affections in the cow, which 

 we have to deal with, is Pleuro-Pneumonia, or combined inflamma- 

 tion of the lungs and pleurae. There are two kinds of Pleuro- 

 pneumonia — the simple and the contagious. On account of the 

 structural arrangements of the lungs of the cow, I have seen post- 

 mortem appearances exhibited in the lungs, resembling those of 

 pleuropneumonia (contagious^, but which I have traced to a needle, 

 or wire, passing in its course from the stomach to the heart, through 

 these organs; and I have had numbers of cases — single, solitary cases — 

 of simple pleuro-pneumonia, which showed all the mdixh\ed post-mortem 

 appearances of contagious pleuro-pneumonia, but the lungs were of a 

 more purpley hue, and more gritty. 



536. Simple Pleuro-Pneumonia. — The symptoms are analogous 

 to those of the contagious form, (par. 537 ) but of a more acute nature, 

 and the cases are solitary, i.e., there is not a general outbreak of the
