uman Foods. Cases 85-114.—The utter dependence 
of man for sustenance upon vegetable products lends ex- 
ceptional interest to the consideration of plants as foods. 
hile it is true that man subsists largely upon animal 
food, these animals are themselves dependent upon vege- 
tation, so that human dependence thereon is but one step 
removed. It is our intention, so far as possible, to have 
represented in our food collection every natural vegetable 
substance known to be used as food by human beings, and 
also many of the more important manufactured food pro- 
ducts made from such substances. In the case of culti- 
vated products, it is not practicable to represent all of the 
cultivated varieties, but in all cases, a sufficient number of 
them are ert to illustrate ne nature and range of 
variation. The number of articles in this group is so 
great that it has been found necessary to adopt some 
special method of classification and arrangement. They 
have therefore been grouped in the following divisions: 
A. Underground Portions. 
B. Aerial Stems, Buds, Leaves or Leaf-stems and Flowers. 
C. Fleshy Fruits and Seeds 
D. Nuts and Seeds eaten in the dry state, such as Marrow 
Beans and Peanuts. 
£. The Cereal Grains and a few products of similar nature. 
The articles in each of these classes are arranged in their 
natural botanical sequence, from the lowest to the highest 
plant. 
Group dA—cases 85 and 86—includes roots, rootstocks, 
tubers and tubercles, and bulbs. Although some fruits, 
such as the peanut, are produced subterraneously, it has 
been thought better to place them under fruits rather than 
in this group. In these cases will be found, not only such 
staple root-crops as potatoes, sweet potatoes, yams, taro, 
turnips, radishes, beets, and carrots, but also a large num- 
ber of aboriginal foods, from many countries. Many of
