Landed fresh about 11,000,000 cwts. 
Imported fresh about 1,250,000 ewts. 
Total 12,250,000 ewts. 
Exported fresh about 1,000,000 ewts. 
Balance of fresh = 11,250,000 cwts. 
Subtract pickled herrings 8,000,000 ewts, 
Balance of fresh = 3,250,000 cwts. 
(Where the quantites are, of course, all“ rounded ”’ ones.) 
Now the propriety of subtracting a quantity of herrings 
exported pickled in strong brine, from another quantity landed 
fresh is obviously doubtful. The deductions for ‘‘ waste’’ are 
different, and the composition of the edible parts is also different. 
What the difference may be one cannot say, but it ought to be 
known before the‘ balance available ” is expanded into calories 
and the latter shared out among the population. 
Further it is very doubtful if the 3,250,000 ecwts. that 
results from this computation was eaten fresh in Great Britain. 
“ Less than one quarter of the herrings brought ashore enter 
into home consumption,’ say the Board of Agriculture and 
Fisheries ; while ““ probably not more than 14 or 15 % of all 
the herrings landed in Scotland are consumed in this country, ’ 
says the writer quoted in the‘ Fish Trades Gazette.”"* Taking 
20 % of all the landings of herrings as a reasonable approxi 
mation to the quantity consumed, we get about 110,000 metric 
tons instead of the 160,000 metric tons given by the Royal 
Society Committee. 
The Analytical Data of the Composition of Fish Flesh. 
The quantity of fish flesh available for human food having 
been obtained (or not), the next step is to convert this quantity 
into proteid and fat constituent quantities. Analyses of all
