Growers are warned that the method of treating trees with cyanide 

 of potassium [see this Review, Ser. A, iii, p. 73] has frequently resulted 

 in the discoloration of the tissues or in the destruction of the trees 

 and should only be employed after considerable experimentation.

A correspondent states that in October 1912 the cotton worm moth, 

 [Alabama argillacea, Hb.] suddenly appeared in tremendous numbers 

 in Chnton, N.Y. A few days earlier an equally large swarm appeared 

 in Ontario [see this Review, Scr. A, i, p. 169]. None were seen in Chnton 

 in 1913 and only a few specimens in the autumn of 1914.

This is a record of experiments performed to find the source of 

 nitrogenous compounds required for the gro\vth of Drosophila. The 

 larvae were able to manufacture all the comphcated nitrogenous 

 compounds of their body from one or two amino-acids or from one 

 ammonium salt. Bacteria may have helped in the work of syntheses 

 in these experiments, but 40 successive generations of Drosophila 

 larvae have been raised aseptically on their natural vegetable food, 

 the banana.
