and lard or lanolin, 8 parts. An excellent ointment may be 

 prepared after the following formula: 



Petrolatum 2 pounds. 



Spirits of camphor 2 ounces. 



Spirits of turpentine 2 ounces. 



Oil of peppermint i/ 2 ounce. 



Carbolic acid y 2 ounce. 



Powdered extract of 



belladonna leaves 6 ounces. 



This is to be mixed thoroughly and applied with mas- 

 sage daily after bathing the udder with warm water. The 

 ointment may be rubbed in thoroughly and the udder

 They should be maintained under sanitary conditions in
