2. METHOD OF ANALYSIS OF THE FLESH OF FISHES. 
During the course of the earlier part of the work here recorded a not 
inconsiderable amount of labor was devoted to the study of the methods 
of analysis. After a time the information thus obtained and, what is 
perhaps of as much consequence, the getting of the routine well in hand 
enabled us to turn out the analyses rapidly and with what seemed to us 
reasonable accuracy, at least so far as the principal determinations, 
moisture, nitrogen, ether extract, ash, sulphur, phosphorus, chlorine, 
etc., are concerned. The methods employed were as follows : 
PREPARATION OF MATERIAL FOR ANALYSIS. 
Separation of flesh ( edible portion) from refuse (bones, shin , entrails , 
spawn , etc.), — The specimens as received at the laboratory were weighed. 
The flesh was then separated from the refuse and both were weighed. 
There was always a slight loss in the separation, due to evaporation, 
and to slimy and fatty matters and small fragments of the tissues that 
adhered to the hands and to the utensils used in preparing the sample. 
Perfect separation of the flesh from the other tissues was difficult, but 
* This specimen consisted of only a part of the animal, left lobe of body, and we 
Wore upable to identify the species with certainty.
