* Col. (2) is formed from the data, Ratio of edible to inedible parts, of 
Table p. 99; Cols. (3) and (4) are based on the mean monthly analyses of Table on 
page 103. The rest of the Table is obvious in its construction. The numbers of 
kilos. in Cols. (3) and (4) are multiplied by their appropriate energy-factors, 
9°3 and 4°1, and then we get Col. 5. 
The point of immediate practical importance is this—that 
there is really no statistical, commercial information with 
regard to the fishery that enables us to form any useful estimate 
of its dietetic value to the nation. 
The Herring Fisheriesof the United 
Kingdom. 
The White Paper* prepared by the Royal Society Food 
(War) Committee gives a statement of the mean annual avail- 
able fish supply of the United Kingdom for the period 1909-13. 
It finds the quantities of all species of fresh fish landed and 
imported, and then subtracts the quantities of the same species 
exported and re-exported. The balance is the supply of fish- 
food available for human consumption. Deductions are made 
for “‘ waste,” that is, inedible components (guts, head, gills, 
bones, &c.) and then the fat and proteid values are calculated. 
The latter are expanded into calories. ‘“‘ The cases,” say the 
Committee, “‘ in which the figures are largely conjectural are 
few and inconsiderable.”
