HARD WICKE'S SCIENCE- G OSSIF. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we now 

 publish Science-Gossip at least a week earlier than hereto- 

 fore, we cannot possibly insert in the following number any 

 communications which reach us later than the 8th of the 

 previous month. 



E. W. A. — The worm whose name you request is that 

 familiarly known as the "Hair-worm" {Goniius agiintic7is). 

 It is the one which schoolboys religiously believe is developed 

 by putting a horse-hair in shallow running water exposed to 

 the sun ! The " Hair-worm" passes the first stage of its life 

 within the bodies of some insects. 



H. W. Hitchcock (Hadleigh). — The " Grub " sent us is the 

 larva of the common Stag Beetle {Lucanus cerznis), abundant 

 in your part of the country. 



A Subscriber. — The fern you sent, with young ones grow- 

 ing on the ends of the older fronds, is in the not unusual con- 

 dition called proliferous. The young one may be taken off, 

 when ready, and, if properly potted, will develop into another 

 plant. Your proliferous plant is abtiorinally in the condition 

 which, in the Strawberry is normal — as when the latter puts 

 forth its stolons and buds. 



W. Statham. — Get Cooke's "Manual of Botanical Terms " 

 (London : Hardwicke & Bogue). It is just the kind of book 

 you want. 



Constant Reader. — The shrub you enclosed was Garrya 

 elliptica. 



A. L. S. (Camden-street). — The portion of flower you sent 

 was a Boiigaijivillea. 



V. G. (Waltham-cross). — Could you send us a more perfect 

 specimen of the shrubby plant ? The primrose which you 

 believe to be the Japanese P. is one with much less pretension, 

 Primula denticiilaia. 



Inquirer. — Your specimen, judging from the rough outline 

 sketch sent us, is Rotifcra vulgaris. 



T. V. D. — You can obtain anything you require for an 

 aquarium, marine or freshwater, from JNIr. King, Sea-horse 

 House, Portland-road, London. 



J. M. M. — No charge is made for the insertion of " E.x- 

 changes," unless they extend over three printed lines. 



G. \V. Landels. — We imagine you must be mistaken in the 

 number of legs of the parasite on the Tortoise. Otherwise your 

 description makes it answer to a species ol Ixodes. 



W. J. V. — The only book we know of relative to Felixstowe 

 (except the " Suffolk Traveller " and other county works) is an 

 old-fashioned and incorrect local guide-book. 



R. Hamilton. — The white variety of the Hyacinth you 

 enclosed is undoubtedly a natural variety, and not a garden 

 sport. White specimens of the common Hyacinth are not un- 

 common in some localities. 



R. J. Manning. — No specimen of a plant was enclosed in 

 your letter of May 20th. 



Fred Ahn. — We should be glad to receive an article from 

 you on the subject you mention. 



F. S. — Get Johnston's "British Zoophytes" from some 

 natural historj' bookseller in London. 



D. F. and Alpha. — You will find McNicoll's "Dictionary 

 of Natural History Terms" answer your purpose, as it gives 

 the correct pronunciation of each name, and the Latin and 

 Greek words from which the names are derived. It was pub- 

 lished, we believe, by Lovell Reeve & Co. 



Erratum. — In the article on "Economic Products of 

 Plants " last month, the names of the first two illustrations were 

 transposed. No. 112 is Urceola, and 113 Herz'a. 



J. T. Powell. — The popular character of Science-Gossip 

 does not admit of mere lists of plants or insects being pub- 

 lished, unless they illustrate some general principle. 



J\I. O. H. — Sir John Lubbock's work on the Thysatiitra was 

 published in the Linnean Society's Transactions, in 1862, 1867, 

 and 1869. We are not aware that a new edition of Pritchard's 

 " Infusioria" is in hand. It has been talked of for some time, 

 and is much wanted. 



H. ScADDiNG. — Accept our best thanks for the capital slides 

 you sent. 



H. J. Savorv, Jun. — The insects enclosed in small bottle aVe 

 a species of Long Horn-moth (Adela lie Geerella). 



" R.-vnunculus." — You did not give us any name to answer 

 your query by. From the remains of the plant you sent us 

 packed in moss, we think it is Anemone ranunculoides.
