118 DAIRY CHEMISTRY 



Experiments have shown that butter is slightly more 

 digestible than oleomargarine. As long as oleomar- 

 garine is sold under its own name, there is little 

 objection to its use ; but people naturally prefer 

 genuine butter and cheese to imitation articles, and 

 they should be protected in securing them. It is 

 when oleomargarine is sold as butter that the prin- 

 cipal injury is done to the butter industry. For 

 this reason, laws have been passed regulating the 

 sale of dairy products and prohibiting adulteration.
