Hirshberg" says that yeast and orange juice are among the 

 most important articles of diet for infants. When the new 

 food is generally adopted, we may speak in quite a new sense 

 of the rising generation. 



BAI.D Eagle Threatened. — The bald eagle, the symbol 

 of our country, is rapidly on its way to extinction. Long 

 ago it disappeared from the more settled regions but until 

 recently it existed in considerable numbers in the wilder parts 

 of our country. In 1917, however, the Territorial Legisla- 

 ture of Alaska offered a bounty of fifty cents for each eagle 

 killed and by April, 1919 this had resulted in the killing of 

 5600 eagles. One is inclined to wonder what kind of an in-

 bird at fifty cents a head. A committee looking toward the 

 future protection of the eagle has been formed and we trust 

 may succeed in their efforts before there are no more eagles 

 to protect. 



Zygomorphic Flowers. — What the systematist calls an 

 irregular flower is usually termed a zygomorphic flower by the 

 morphologist. In either case we have been accustomed to 

 form a mental picture of a flower some of whose parts are 

 unlike other parts of the same origin. The most familiar 

 forms are those which the petals are of different sizes or 

 shapes resulting in labiate or papilionaceous corollas such as 

 are found in the mint, figwort and pea families. Such flowers 

 usually face sidewise on the stem and are adapted to the 

 visits of large insects. As to the exact definition of zygo- 

 morphic flowers, even the authorities differ. Originally this 

 type of flower was defined as one that could be cut into two 

 exactly similar parts in a single plane only. If one recalls the 

 structure of a sweet pea, snapdragon, larkspur or nasturtium, 

 he will appreciate the fact that a cut in only one direction will 

 separate the flower into similar halves. But what about tlie
