320 PLEURO-PNEUMONIA. 



stomach ; which makes the breathing still more distressing. 

 After death, the rumen is mostly found crammed with 

 stinking, undigested food, and the effect even upon this 

 almost insensible compartment of the stomach, is shown by 

 its lining membrane peeling off as the mass is emptied out. 



The examination made after death generally displays 

 both sides of the chest, and the heart bag, full of fluid of a 

 bloody tinge. Loose flocks of lymph, about two inches in 

 length, adhere to the inside of the ribs, the outside of the 

 lungs, and the anterior surface of the diaphragm. The 

 lymph is of a dirty straw colour ; it likewise lines the 

 heart bag, and sticks to the outside of the heart itself. 

 The blood within the body is darker than usual ; and occa- 

 sionally the cellular tissue is injected, especially upon the 

 surface of the frame. The characteristic appearance which 

 marks the complaint is, however, found within the lungs. 

 These, when cut into, are of various tints, from the palest 

 pink to the darkest modena. Their variegated aspect 

 pleases the surgeon as well as surprises him, especially 

 when he first cuts into the lungs, for then the colours are 

 very bright, and the distinction between them very marked. 

 Between these hues travel eccentric whitish lines, taking 

 no definite course, or being of no definite thickness ; but 

 running here and there, and being of all imaginable breadths. 

 It is this difference of hues, divided by numberless whitish 

 lines, which has gained for the lungs the term of marbled ; 

 a word that very well prepares the imaginative spectator for 

 the sight which he will behold. Added to all which, we 

 have said the air tubes and cells are plugged up with a thick 

 frothy mucus ; and whoever sees the organs of respiration 

 in such a state requires nothing further to make him com- 

 prehend the cause of death. 



With regard to medicinal measures, these must be very 

 gentle. Every caution is necessary to husband the strength ; 

 and active measures will not always check the disorder. 

 During the first stage the symptoms merely denote general 

 irritability, and the treatment required is merely such as 

 will check that which the symptoms suggest. If the loss 

 of a very small quantity of blood will produce an effect 

 upon the disposition, something may be suspected as lurk- 

 ing behind the irritability ; but if the animal endures a full
