Ether in forcing Plants {Bev. Hort. Beige, Jan. 1901). — M. 



Johansen has studied the effect of this substance, and finds that it 

 resembles the action of frost, in that plants like Lilac will not flower 

 imless subjected to a low degree of temperature. By means of ether he 

 has made Lilac blossom in October, the vapour of ether thus bringing 

 about the internal chemical changes usually effected in the depth of 

 winter during the period of repose. — G. H. 



Eucalyptus and Malaria (BiUl. Bot. Dep. Jam. March 1901). — 

 It is thought by some that the Eucalyptus absorb so much moisture that 

 they dry up the marshes where mosquitoes breed ; but others think that 

 these insects will not approach the trees. According to the experience of 

 Mr. W. A. Sanders, living in the Sequoia sempervirens region of Cali- 

 fornia, it appears that the latter is, at least, true in his neighbourhood. 

 He planted a grove of E. globulus (now 140 ft. high). He says : " There 

 has never been seen a single mosquito larva in the irrigating ditch from 

 the spot where it enters the first shade of these trees to where it emerges 

 from them 200 yards away ; while above and below mosquito larvic are 

 plentiful." -G. H.
