highly porous bodies which though greatly enlarged preserve the 
shape and appearance of the original, and being readily acted 
upon by the digestive juices form valuable and economic foods. 
The products are also readily emulsified by water and other 
liquids and lend themselves to use in the arts for sizing, pasting, 
etc. The method in question is essentially distinguished from 
other processes by being based upon the explosive action of the 
liquid contained in air-dry starch, and the principal features of the 
invention are set forth in the twelve claims of the inventor as 
allowed in the grant. Dr. Anderson’s invention is based upon 
studies made in the laboratories in the Garden, and he is now 
engaged in the perfection of machinery and apparatus by which 
the products in question may be made in commercial quantities.
