Douglas Mixture. — The Douglas mixture is not so popular as 

 it was years ago, but it is a cheap tonic that many people think is 

 all right. As it is astringent as well as tonic, it should be given 

 sparingly for some troubles. This is an improvement on the oH 

 recipe for Douglas mixture and will give better satisfaction: 



Sulphate of iron, quarter pound; aromatic sulphuric acid, 4 

 ounces; and one gallon of water. The aromatic solution is made 

 in alcohol, with tincture of ginger and spirits of cinnamon added, 

 and is much better for internal use. 



To make: Place the sulphate of iron and the acid in a strong 

 earthenware pot; pour on the water and stir well with a stick. 

 Cover the mixture with a woollen cloth and leave for a day. Then 

 run oil into glass bottles or stone jug and cork tight. 



Dose: A teaspoonful to each half pint of water or the same 

 amount mixed in mash, every third or fourth day. The drinking ves- 

 sels must not be tin or iron; nothing except earthenware or wood. 



Used and made right this improved tonic is a great addition to 

 the list of cheap poultry tonics. Like all cheap things, it was used in- 

 discriminately and got in bad repute..
