 including the cost of cooking. The poor man wastes in purchasing proVender; his wife wastes in preparing IL for the table. When an intelligent person buys . coat, he has pretty fair idea as to whether 1t fits him and how it will wear. | But when he invests In meat and pota- toes, he has little information as to now much nutriment they contain or wheth- CT 1t Is of kind suited to his bodily re- | quirements.
 Professor Atwater has an apparatus | at Wesleyan university for measuring l the physical income and outgo of hu- man beings. It is metal box, inside | of which q man is placed. He stays | there for several days, during which he is fed on carefully weighed quantities | of certain foods. A current of air Is | drawn through the box by q machine | pump. Not only is all the waste from the mans body analysed and weighed, but the air is subjected to analysis before It goes in and after 1t comes out of the box.
 By the latter analysis it is discovered just what elements and how much of them has been given off from the lungs of the man in breathing. Everything that goes into the body of the subject being known, as well as the outgo, it is easily ascertained what has been used l to build up the tissues, to make blood, etc. The man in the box, which has glass windows, may spend his time in idleness, or he may be occupied actively for several hours of the day. In this way comparisons are obtained as to food consumed and results accom- plished under varying conditions.
 Most educated people have queer mo- tions about foods. It is generally i'm agined that an egg contains as much nutriment as pound of lean beefsteak. As matter of fact it has forty per cent. less of nutriment, pound for pound. Beef srloin is only seventy-five per cent. nutritious as beans and peas. Chicken and turkey are ahead of peas and beans in this respect, being the most nutritious foods known. Shad and mackeral are as nutritious as srloin steak. Lean beef is nearly three- fourths water.
 Dealers say that the demand for fish is actually increased to considerable extent by the popular belief that it is good brain food. The reason for this is supposed to be that fish contains a great deal of phosphorus, an element that is more abundant in the brain and nerves than in other parts of the body. But the fact is that there is no special abundance of phosphorus in fish. If there were it would be of no impor- tance. The widely-circulated phrase "Without phosphorus there is nc thought" was originated by German half in jest.
 The elder Agassiz once delivered a lecture On the importance of fish cul- ture-it was in Boston-and remarked in a joking way that fish was an excel lent brain food. From this saying and from the oft-quoted phrase of the Ger man scientist referred to, has beer derived the accepted idea on this sub ject.
 Fish eating does not promote cerebra activity.
 Professor Atwater has invented { [, l : produced by various foods. The foot selected for trial is burned in vesse surrounded by water. A thermomete
 registers the rise in the temperature O 5 the water, the quantity of which ii /; known. Then an equal amount of thu same food is burned in the human
 body. Of course, all food digested un t dergoes a process of chemical com - bustion.
 - If the amount of potential energy de
 veloped in the man is equal to that in q dicated by the rise in the temperatur @ of the water it is proved that tn energy power of any human being F precisely equal to the energy powe
 that has been absorbed in the shape o ,, food. Surplus energy, however, may b stored as fat in the body. The fat
 stored fuel. Americans store excessiv quantities of such fuel by eating to ? much starch, sugar and fats.
 With small equipment of knowledg 0 on this subject the poor man could SC ,' lect his food with vastly greate economy. In other words, he could liv l. much better for less money. He ough y to be taught to select such foods a
 wheat-flour. cornmeal, beans, milk, an g the cheaper cuts of meats. High-price 5. foods are in general uneconomical. Tn - maxim that the best is cheapest doe l. not apply to foods. l. The average man requires f1fty-nin
 ounces of food per diem. He consume ,t thirty-seven ounces of water and al o sorbs in breathing, thirty ounces ( r? oxygen from the air. His total bodil Il income therefore is about eight pound 10 daily. What he needs for his suppol - each day is four and one-f1fth ounce
 of flesh-forming albumen, two ounce of fat-enough to make fair-sized car q dle-seventeen and one-half ounces n sugar and starch, four-fifths of 8 a ounce of mineral matter-such as con .o mon salt. potassium, etc.-two quart if of water and 159 gallons of oxygen " much water is contained in solid food
