“ Experience of fattening gives two pounds per day, or fourteen pounds per week, as what can be attained on an average, and for a length of time. If we considered half a pound per day as fat, which is not more than probable, there will be one and a half pounds for flesh, which, reckoned as dry material, [372] will be about one third of a pound, which is assimilated in increase of fibrin, and represents only one and one third to two pounds of substances rich in protein, beyond what is required for her maintenance. ”
