Among the fishes the least waste material is found in the halibiit, with 

 17.70 per cent, and the greatest in the flounder/which contains 66.8 per 

 Cent; yet the same price woukl probably have to be paid for each. The 

 average protein content in the fishes is somewhat lower than the cor- 

 responding average for the meats. The amount of fat found in fish is 

 small, salmon, with 8.8, having the maximum, and flounder, with .3 per 

 Cent, the minimum. The shell fish all have high percentages of waste 

 material. 



Table II is very interesting and quite important in its way, both as 

 regards food value and food economy. It is not, however, in a convenient 

 form for the calculation of dietaries; a difficulty overcome by Tables III 

 and IV, which, respectively, show the amounts in ounces of nutrients 

 per pound, and parts of an ounce per ounce, of the different foods repre- 

 sented. In the tables the data given for the friiits and nuts have been 

 estimatecl from analyses made by Mr. George E. Colby of this Station, 

 that for California flour and bread from analyses of my own, while the 

 figures for the remaining foods were calculated from data published by 

 Professor Atwater. 



Having these tables before us, the making up of dietaries is a very simple 

 matter. It should be said that in these tables the figures for Nos. 1 to 

 15, inclusive, include the waste; while for the remainder the edible por- 

 tion only is represented.
