Appendices to Twenty -second Annual Report 



The analysis of the muscle of this fish is given as follows, taking the 

 "thick " and the "thin " separately : — 



Thick. Thin. 

 Fats, . . 11*85 per cent. 17*42 per cent. 



Other solids, . 22-94 „ 20-36 „ 



Total solids, . 34*79 per cent. 37'78 per cent. 



The method is, I understand, to extract the fat from the tissue by 

 ether, then after distilling off the ether, to dry the fat at 100° C, and 

 weigh. The residue of the tissue having been also dried at a high 

 temperature and weighed, the two results are added together to give 

 the sum in total solids.
