HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



J. C. D. — The dried plant with seeds is a specimen of 

 Veronica hederifoliii. The moss is Dlcranum bryoidns. 



E. L. — Your suggestion is worth thinking over, but it is a 

 dangerous task to meddle with a usage that works well, and 

 to peril it for an unknown result. It might be tried, however. 

 Many thanks lor your kind offers. 



Young Collector. — There is no doubt that difference in 

 the mineral constituents of soils influences the colours of 

 certain plants. Your fern is the Bladder-fern [Cystopteris 

 fragUis). The other specimen is the Fir Club-moss {Lyco- 

 podium selngo). 



Erratu.!!. — In geological column last month, for " Ancient 

 Cheshire forest" read " Ancient Lancashire forest." 



T. W. Cowan. — Your specimens were as follows: — No. 1. 

 Bugulaneritina ; 2. Antennularia ant ennina {worn specimen); 

 3. Hydrallinannia falcata ; 4, Antennularia antennina fin 

 perfect condition); 5. Halichondria riimnsa (I. I'olyzoa ; 

 2 — 4. Hydrtiid Zoophytes ; 5. Sponge). — iV. H. K. 



Morbid Structurks. — If Medicus will apply to Mr. 

 Wheeler, 48, Tollington Road, HoUoway, London, for his 

 list of microscopic objects, he will find that it contains many 

 morbid structures, and he might be supplied with others not 

 mentioned in the list. — A. C. II. 



M. D. LoND. — Your specimen is exceedingly difficult to 

 make out. It is not a British plant, and has all the characters, 

 both as regards leaves, inflorescence, and corolla, of a 

 Lonirera. It is possibly canencens. Your description of its 

 being a " trailer." however, is difficult to apply, unless the 

 word is used loosely. Can you send us a,fresh specimen, and 

 tell us when it blooms ? 



R. H.— The egg sent is that of the "Pewit," or "Lap- 

 wing," or " Green Plover," as it is severally called ( Vanellus 

 cristatus). 



W. Eyre. — Your specimen is a lichen, commonly called 

 "Cup-moss " [Cenomyce pixidata). 



Microscopic Slides, — Will Mr. Powell kindly favour us 

 with his address, as it has been mislaid, that we may corre- 

 spond with him relative to the six slides sent? 



C. L. A.— The specimen is Acacia alata. 



Clericlts. — You will find a good account of the Palmate 

 Kewt (Lophinus palmatiis) in Cooke's " British Reptiles," 

 published by Hardwicke, iy2, Piccadilly, London. 



W. AsHTON.— See article on "Collecting and Preserving 

 Lepidoptera," by Dr. Knaggs, in the June number of 

 SciENCE-Gossip for 1872. 



Mari.\n H. — Any good microscope-dealer will supply you 

 with the slides you require. 



J. M. D. AsHBURY. — Could you send us another exuvial 

 skin of the smooth newt ? If so, please pack it so as to carry 

 well through the post. 



W. Greensladk. — 1. The use of iVaZic letters for specific 

 names in the London Catalogue of British Plants indicates 

 that the plant is believed to have been originally introduced 

 into this country by the agency of man, as distinguished 

 from the agency of natural causes alone. This explanation 

 will be found given more curtly on page 31 of the Catalogue. 

 2. The use of the asterisk (*) bears relation to the nos., notto 

 the na/nes o( the plants. The first edition of the Catalogue 

 was printed in 1844, and the species were then numbered 

 regularly and consecutively throughout the list. Since that 

 original date, the progress of discovery, and various changes 

 in technical arrangement, have led to the interpolation of 

 several adilitional names. In such instances the u-e of the 

 asterisk is resorted to, in order to avoid the inconveniences 

 which would result from le-numberiiig the entire series of 

 names in each successive edition. " Collecting " pebbles has 

 not \et been published in Gossip. There is a book on this 

 subject |)ublished by Routledge, price 4s., but we cannot 

 recommend it.
