Browne x reports the results of an examination of the composition 
of sprats, " a well-known fish." A specimen was bruised in a mortar 
and dried at 212° F. One hundred parts of this contained : Water, 
63.65; oil, 18.60; solids, 17.75. Of the solids, nitrogen constituted 
11.53 per cent, equivalent to 1.94 per cent of the original sample, and 
ash, 2.21 per cent. The composition of the ash. is given in the fol- 
lowing table :
