richness to the blood, and giving tonicity and health to the 

 fibrouSj serous tissue, from which the fluid causing the 

 swelling arises. In pleuro-pneumonia in cattle, after fev^er 

 has abated, nothing will restore and prevent effusions of 

 serum, or fluid, in the chest, like sulphate of iron; and 

 effusions in the chest of cows, and neat cattle, is the cause 

 of very many deaths. The effusions form connecting links 

 between the lungs and the sides, from which adhesions 

 take place in that disease, and from which the animal cau 

 never be restored to good health, although it may live for 

 a year or two. How important, then, is a medicine 

 offering so much hope ! 



In addition to the diseases just named, sulphate of iron 

 is the medicine to be used in all cases where the powers of 

 life are low and depressed. In red water in cattle, bleeding 

 internally in all animals, dysentery, purpura, scarlatina, 

 and in debilitating diseases generally, no medicine offers 

 so much as the sulphate of iron. 



Observe. Sulphate of iron should not be given while 

 inflammation and fever lasts; it is time enough to give it 

 after all irritation has subsided. It should always be com- 

 bined with a vegetable tonic, such as gentian, or ginger. 

 Iron changes the dung to a green color, as if the animal 

 was at pasture. 



Doses. For horses and cattle, the dose is two to three 

 drachms, with the same quantity of powdered gentian, two 

 to three times in the day, to be given, mixed in a quantity 

 of cold water. Drench out of a bottle, if the animal does 

 not eat it readily, mixed with cut, or soft feed.

 solid state, this preparation is valuable for bleeding wounds, 

 to stop the flow of blood — which it will readily do, if 

 properly applied, and the blood vessel that is wounded is
