INTRODUCTION. 
Shortly after the publication of last year’s Report in 
March, 1917, it became evident that some of Dr. Johnstone’s 
results in regard to the analysis and the resulting food value 
_ of fish, which were published in brief form in that Report, 
were not in accord with statements made authoritatively 
elsewhere by some other scientific men. Under these 
circumstances, knowing the care and skill with which 
Dr. Johnstone’s work had been done, I urged him _ to 
continue his investigations for another year and to repeat 
the analyses in order that we might publish the reconsidered 
results in fuller detail in the present Report. 
| In view of the importance at the present time, in the 
interests of the public welfare, of any such contributions as 
this to a knowledge of correct food values, I had no 
hesitation in recommending to the Chairman that I should 
_ be authorised to lay before the Committee for publication a 
somewhat longer and more detailed Report than those of the 
_ last couple of years.
