contains, as a rule, a larger percentage of oil or fat, and a 

 smaller one of organic-nitrogen-containing matter, than the 

 new-process linseed meal. Aside from the stated causes

 Our inquiry into the comparative value of both kinds of 

 meal as a fodder ingredient of the daily diet for milch cows 

 has been carried on with articles of the following average
