It is interesting to note the relative amount of fat and albuminoids in the corn and cobmeal mixture as compared with the sugar meal. _Constituents_. _Corn and cob meal_. _Sugar meal._ _Per Cent._ _Per Cent._ Water 13.37 6.10 Salts 1.43 1.17 Fat 2.81 11.16 Carb-hydrates 65.99 52.66 Woody fibre 8.03 8.64 Proteids 8.37 20.27 —_Bulletin_: _Iowa Agricultural Experiment Station_.
