General Remarks on the Analytical Results. 
It is necessary to make some remarks with regard to the 
general question of the accuracy of the analyses. 
‘First of all we must note that the totals for water, oil, 
proteid and ash in the Manx Summer Herrings of 1916 and 1917 
show a deficiency. The mean results for all the samples 
received during each month are given in the Table on p. 103. 
Excluding the analyses of May, 1916, we see that the mean totals

_ The cause for this deficiency was investigated in a pre-
