HA RD WICKE'S SCIENCE- G OSS IF. 



To OUR Recent Exchangers.— We are willing to be helpful 

 to our genuine naturalists, but we cannot further allow dis- 

 guised Exchanges like those which frequently come to us 

 to appear unless as advertisements. 



H. E. G.— Get Bennett's "Manual of Cryptogamia," pub- 

 lished by Longmans at, we believe, 6s. 



C. H. Betts. — We are much obliged by your complimentary 

 query, but we beg to say that, as a magazine or oiherwise, 

 Science-Gossip is perfectly free, and sails under no auspices 

 except those of publisher, editor, and generous and loyal con- 

 tributors. It has been issued thus for twenty-six years, and 

 perhaps no other popular scientific journal has such a world- 

 wide or large circulation. Our views are perfectly independent, 

 although we endeavour to make them comprehensive and 

 .sympathetic. ^ ,, , , 



C. T. MussoN (Hawkesbury, N.S. Wales).— ISIany thanks 

 for specimens of "green roses." They are not uncommon, 

 and on this side of the world we have known florists who made 

 money by cultivating " green rose " trees. Of course, it is a 

 question of return of the petals to the foliar or green condition. 

 The real inquiry ought to be as to whether this greenness is due 

 to the presence of chlorophyll, or otherwise.
