NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

 orders, and orders for the supply of this Journal, should be 

 addressed to the Publisher. All contributions, books, 

 and pamphlets for the Editor should be sent to 192, 

 Piccadilly, London, W. To avoid disappointment, contri- 

 butions should not be received later than the 15th of each 

 month. A'o notice whatever run he taken of communica- 

 tions which do not contain the name and address of the 

 writer, not necessarily for publication, if desired to be with- 

 held. We do not undertake to answer any queries not 

 specially connected with Natural History, in accordance 

 with our acceptance of that term ; nor can we answer 

 queries which might be solved by the correspondent by an 

 appeal to any elementary book on the subject. We are 

 always prepared to accept queries of a critical nature, and 

 to publish the replies, provided some of our readers, besides 

 the querist, are likely to be interested in them. We do not 

 undertake to return rejected manuscripts unless sufficient 

 stamps are enclosed to cover the return postage. Neither 

 do we promise to refer to cr return any manuscript alter 

 one month from the date of its receipt. 



R. H. W. — We cannot insert mere lists, either of plants or 

 insects. 



T. M. H.— Tobacco-water, or strong soap-suds, may be 

 advantageously used for destroying the blight on rose-trees. 



A Subscriber. — Your query about lightning-conductors 

 does not come within our province. Inquire in the pages of 

 some journal devoted to mechanics or physical science. 



S. A. Stewart. — The moss is Hypnum filicinum. 



Will some of our courteous, but eager, correspondents, 

 remember the inexorable limits of space, and that it is impos- 

 sible to publish more than our monthly columns will allow ? 

 We cannot depart, except under very special circumstances, 

 from the rule of priority in contributions. 



Rev. R. B. C— See zoological paragraph in last Science- 

 Gossip on " Fish building nests." 



Constant.— See " Half-hours by the Sea-side," just 

 published. Kardwicke, 192, Piccadilly. 



L. V. Hamel. — You will find all the instruction ynu need 

 in an article published in the February luimber of Science. 

 Gossip, headed, " A Simple Method for Preparing Skeleton 

 Leaves." We thought that as this was so recent, you must 

 have seen it. 



W. Aldridce. — See paragraphs in present number on 

 drying fungi. Most of the treatment is applicable to gourds.

Rev. B. B. C— See paragraph in the zoological column of 

 last number of Science-Gossip. 



C. R. W. NuRSEY. — The supposed Foraminifer seems to 

 belong to the genus Dactylopora ; but your sketch shows no 

 pseudopodal apertures. An actual examination will be 

 necessary to determine its nature. 



T. G. Darling.— The larva in the pear sent appears to be 

 that of one of the small Gall-gnats, or Midges {Cecidomyia). 

 Most likely it also feeds on the fruit of the hawthorn, by 

 which its abundance is kept up. The only plan of destroying 

 it would be by lighting weed fires near the trees at the time 

 of blossoming.

 pellucidu/n.
