HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

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

 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. No notice whatever can be 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 

 can we promise to refer to or return any manuscript after 

 one month from the date of its receipt. All microscopical 

 drawings intended for publication should have annexed 

 thereto the powers employed, or the extent of enlargement, 

 indicated in diameters (thus : x 320 diameters). Communi- 

 cations intended for publication.should be written on one 

 side of the paper only, and all scientific names, and names of 

 places and individuals, should be as legible as possible. 

 Wherever scientific names or technicalities are employed, it 

 is hoped that the common names will accompany them. 

 Lists or tables are inadmissible under any circumstances. 

 Those of the popular names of British plants and animals 

 are retained and registered for publication when suffi- 

 ciently complete for that purpose, in whatever form may 

 then be decided upon. Address, No. 192, Piccadilly, 

 London, W. 



H. D., H. M., J. S., Jun. — We do not pretend to name more 

 than two specimens at a time from the same individual. In 

 two instances to send six, and the other ten specimens, is 

 too unreasonable to cause any hesitation in putting the rule 

 in force. 



W. H. S. — It was distinctly stated that no discussion of the 

 question " Do insects feel pain? " would be permitted to ex- 

 tend beyond the December number. 



J. S., Jun. — No. 1 is Crisia denticulata. No. 7 a sea-weed, 

 Corallina officinalis. No. 10 a sea-weed in bad state, 



E. M. H.— On palm is Graphiola phcenicis. Only by pick- 

 ing off and destroying the leaves affected. Will you send us 

 further specimens, with locality ? 



W. C. P. — It is the " Spindle tree,'' Euonymus europaeus. 



J. M. — You will not induce reptiles to eat during winter. 

 All you can do is to let them alone, giving them the opportunity 

 of burying themselves from the frost, under leaves, moss, &c. 



A. L.— We cannot answer your question this month. If 

 any information is obtainable, it shall be given in a future 

 number. 



A. R.— We cannot suppose that the constantly repeated 

 notice that exchanges must be written out fairly and legibly 

 is not read ; our only conclusion must be that it is disregarded. 

 Of course we can only resort to the penalty, — that is, non- 

 insertion. We cannot write out such notices afresh, adding 

 address, and giving the generic names in full. If such 

 notices are to be inserted gratuitously, surely it cannot be too 

 much to require that they should be written as they are to be 

 printed. 



G. E. Q.— The Eel-pout is Lota vxtlgaris. 



Constant Subscribers will know that we have always 

 insisted upon name and address being furnished, so that no 

 attention will be paid to their communications. 



A. C. — The Diatoms are, 1. Coacinodiscus radiatus; 2. Pin- 

 nularia nobilis. 3. Campylodiscus cribrosus. 4. Endictyi 

 oceanica = Melosira cribrosus, Sm. 5. Aulacodisrus marguri- 

 taceus. 6. Coscinodiscus perforatus. 



Italian Bees. — "A. L." wishes to know where, and at 

 what price he can purchase a Queen. 



J. J. Exon wants to know where he can obtain Professor 

 Goodsir's tube for studying infusoria. 



S. S. desires to know the most approved method of hatch- 

 ing chickens by artificial means.
