a period of four days would be quite effective, provided the 

 infested fruit is collected daily and submerged in water. The 

 two last methods, however, could be advantageously combined. 

 Infested fruit could be collected daily and thrown into a barrel 

 or tank of water, and when a sufficient amount has accumu- 

 lated the maggoty fruit could be buried. This would do away 

 with the daily plowing or digging of trenches, filling in and 

 tramping of the soil. In large orchards, however, the daily 

 gathering of infested fruit would be rather expensive on 

 account of the labor.

The Seventieth Birthday of Prof. Metschnikoff. 

 Science for Dec. 25, 1914, calls attention to the fact that Prof. Elias 

 Metschnikoff (or Elie Metchnikoff), "the eminent Russian pathologist, 

 who for the last twenty-six years has been engaged in research at 

 the Pasteur Institute in Paris, will be seventy years old next" May 

 and states that a Festschrift for him has been in preparation. It should 

 not lie forgotten that in earlier years Metschnikoff published import- 

 ant papers on the embryology of scorpions (1871), of chilognathous 

 myriopods (1874, 1875), of TTetniptora and other insects (1866).
