HARDWICKE'S SCIENCE-GOSSIP. 



[April 1, 18C7. 



NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

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

 addressed to the Pi/blishkr. 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 can be taken of communi- 

 cations 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 mierht 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 

 cannot 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 manu- 

 script 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). Communications 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 inad- 

 missible under any circumstances. Those of the popular 

 names of British plants and animals are retained and regis- 

 tered for publication when sufficiently complete lor that 

 purpose, in whatever form may then be decided upon. 

 Address No. 192, Piccaiiii.lv, London', W. 



F. A. C. — Menyanthes trifoliata grows on Hampstead 

 Heath ; the others are American plants. Not stated whether 

 dried or growing plants are required. 



W. A. L. — As C. B. resides in Vienna, he cannot answer 

 for himself. We know of no place in England where the 

 articles can be obtained. 



J. P. and T. H. N. — As there must be a limit somewhere, 

 we have resolved not to admit apparatus into our Exchange 

 column, which is designed for objects in Natural History. 



E. D. C— Most probably. 



E. T. S. — Macrosporium sarcinula. 



R. G. — The Podura, doubtfully referred to Achorvtes fime- 

 taria at p. "2, accords with the JJesoria viatica of Nicolet ; 

 but his descriptions are so concise that it is difficult to speak 

 positively. — I. 0. W. 



A. B. P. — A great deal of nonsense ha« been written about 

 " Gregarines " developing into Pediculi. There is more 

 romance than truth in the newspaper reports. 



R. H. — The book you mention is probably Daniel Cooper's 

 " Flora Metropolitana : or, Botanical Rambles within Thirty 

 Miles of London" (S. Highlev, 183b); or possibly the Middle 

 sex portion of Turner & Dillwyn's " Botanist's Guide." Both 

 these, however, have been superseded by Watson's "New 

 Botanist's Guide ; but Dr. Trimen's announced " Flora of 

 Middlesex " will be likely to give you the most recent infor- 

 mation. — N. 



T. H., Ju.v. — 1. Hypnum (Brachythecium) rutabnhim ; 2. 

 The same, vat. Q longiselum ; 3. Atrichum undulatum 3 



4. Hypnum (Brachythecium) Velutinum.—R. B. 



A. N. — Forwarded to E. H. R. as requested. 



H. M. G. — "Taxidermy made Easy" (Gardiner, 52, High 

 Holborn, W.C., price Is. 6d.) contains Waterton's Method of 

 Stuffing Birds, reprinted from his " Wanderings." 



W. H. — See answer to H. M. G. above. For insects, " The 

 Butterfly Collector's Manual" (Kent & Co.), or the volume of 

 " Insect Miscellanies." 



H. P. A. — We cannot judge from the name alone. Send 

 drawing and description. 



Acarus.— Letters and specimens from the following duly 

 leceived :— W. W. S., A. S., W. T. I. 



W. C— See our oft-repeated notice at the head of this 

 column. 



J. G.— Thanks for your offer. See the reply to H. M. G. 



A. J. and R. H. N. B. — Compel ns again to say that we 

 cannot notice communications where the name of tlie writer 

 is not given. 



T. P. — Thuidium tamariscinum, Br and Sch. (Hypnum 

 tarn. Hedg.), Common. — R. B. 



H. G. G — 1. Ompliulod.es verna, a Boraginaceous plant, 

 nearly allied to Cynoglosswm, of which genus it was formerly 

 considered a species. 2. Not frequent. 3. The white-flowered 

 variety of Lamium purpureum is not uncommon. — B. 



C. H. G. — 1. No. 2. We cannot say. 3. Question is not 

 clear. 4. None specially. 5. Dr. Carpenter's work on the 

 Microscope, pp. 618, second edition. 



Waterton's Process. — We have to thank numerous cor- 

 • respondents who have sent manu-cript directions for this 

 i process, or indicated in what books it is to be found. 



J. S. K. — Your Lichens are common species, and may he 



', found in any old orchard. We cannot undertake to return 



specimens ; duplicates must be kept, with corresponding 



numbers. 1. Ramalinn fraiinea; 2. Rnmalinu fustiginta ; 



' 3. Ecernia prunastri ; 4. Borrera ciliaris; 5. Usnea hirta. — 



I R. B. 



J. E. T.— Tortilla fallax.— R. B. 



A. W. C. — They may be found in a recent number of the 

 Microscopical Journal. 



M. A. B. — We should think one of the large silk-houses in 

 the City, but much depends upon the quantity you have to 

 dispose of. 



Youghal. — Your specimen is a portion of a vulcanic bomb, 

 probably introduced with ballast. — R. T. 



W. M. — Tne report is unfortunately derived through too 

 trustworthy a channel to leave much hope of its being un- 

 true that Dr. Livingstone, the celebrated African traveller, 

 has been murdered bv natives.
