statistics of the food consumption of the families of laboring 
classes in Massachusetts and Canada. ‘The data thus obtained 
as to kinds and amounts of foods consumed were sent to Mid- 
dletown, and from the analyses above referred to, the quantities 
of nutritive ingredients in fifteen dietaries of as many families 
and boarding-houses were estimated. The results were pub- 
lished in the Report of the Massachusetts Bureau of Labor 
for 1886. With this exception the food investigations up to 
1890 had been chiefly along the lines of the chemical compo- 
sition of American food materials. In 1890 a series of accu- 
‘rate studies of dietaries were undertaken by the Station in 
cooperation with the U. S. Department of Labor, and up to 
January, 1895, twenty-one such studies of the food consump- 
tion of families of mechanics and men in professional life had 
been carried out. ‘The main results were given in the Reports 
of the Station for the year 1891 to 1894 inclusive. They are 
to be given in more detail, with accounts of other work in 
this direction, in a publication of the U. S. Department of 
Labor. . 
ANALYSES OF FOOD MATERIALS EXHIBITED AT THE WORLD'S 
FAIR, 
In connection with the studies of dietaries, a considerable 
number of food materials have been analyzed. ‘The principal 
work in this direction since 1890, however, has been in the 
analyses of foods exhibited at the World’s Fair. 
As a member of the Jury of Awards at the Fair one of us 
(W. O. A.) was requested by the Executive Committee on 
Awards to take charge of an examination of some of the more 
interesting and important food materials there exhibited. This 
investigation was made in accordance with the purpose of the 
World’s Columbian Commission, which was to make the Fair 
educational and to provide that its influence should continue 
after the Fair itself should end. Probably no other occasion 
has offered such an opportunity for comparison of materials 
used for the nutrition of man. Certainly none has been so 
favorable for collecting specimens of food materials, including 
especially the animal foods, which are most interesting to usin 
the United States. Part of the analyses were, with the codpe- — E 
ration of the Station, carried out at Chicago during the Fair.
