trade terms as " butterine ". All mixtures containing 

 animal fats made in semblance of butter are legally 

 known as oleomargarine. When coloring matter is added 

 to butter fat, within the meaning of the law the product

 oleomargarine must be branded or marked as the Com-

 oleomargarine, must be used to designate the product.

 Commissioner to employ a chemist who shall ascertain 

 whether or not oleomargarine contains any ingredients 

 that are deleterious to health. Appeal may be taken 

 from the decisions of the Commissioner to a board com-
