HARD WICKE 'S S CIENCE ■ G SSIP. 



NOTICES TO CORRESPONDENTS. 



J. A. C. — Some mistake must have occurred, for your note of 

 April 29th contained no specimen of any kind, flower or other- 

 wise. We believe that the paper you refer to was read at the 

 West of London Club. 



"A Reader."— Please send us your name and address, and 

 we will send you the name and address of such a person as 

 you require. 



A. D. M.— "The Transformation of Insects, by Professor 

 Duncan, gives numerous illustrations of the structural parts of 

 insects. 



F. W. B. N.— Election into the Linnean Society- is by pay- 

 ment of an entrance fee of si.x guineas, and an annual subscrip- 

 tion of three pounds. A candidate must have his admission 

 paper signed by three Fellows, who will testify to his fitness 

 from "a personal knowledge of his work and writings," &c. 

 Admission to the Royal Society is by an entrance fee of ten 

 guineas. Only fifteen are elected every year, and are chosen 

 on account of the scientific work they have done. Peers of 

 the realm are F.R.S. without election. 



P. E. C. — For full details about aquarium keeping, marine 

 and fresh-water, stocking aquaria, balance of animal and veget- 

 able life in ditto, consult Taylor's "Aquarium : its Inhabitants, 

 Structure, and Management." Published at 192, Piccadilly. 

 Price 6s. 



Rev. W. H, P.— We see no reason why the plants you refer 

 to should not be eligible as e.xchange. 



C. J. A. Crawley. — The umbelliferous flower enclosed is 

 that of the Wild Chervil {C!ni;rophyllus Sylvcstre). No. 2 is 

 more important, for the "succulent plant" is the Toothworth 

 (Lathrea sgnainaria), which is found parasitically growing on 

 roots of alder, &c. We cannot pronounce on the Helix until 

 we .see some specimens. 



Bervll.— The "Mineral" Magazine referred to was an 

 abbreviation for the " Mineralogical " Magazine. 



G. H. Ravner.— The name of the commonest living species 

 of coral known as " Madrepore " \s Madrejiora plantaginca ; 

 the word " I\Iadrepore," however, is very loosely used, and 

 often includes several genera of living corals, besides fossil 

 ones. . 



F. W. S.— The fungus on the nettle leaves sent is that called 

 the " Cluster-cup" {Aicidiitm iirtiae). 



H. J. M'GiLL. — Your specimens are as follows :— No. 

 I. Flowers of the White Beam tree (Pynis aria). 2. Three- 

 fingered Saxifrage [Saxi/raga tridactylites). 3. Field Ve- 

 ronica {V. agnstis). 4. Small Sand Rocket {Brassica viiiiiera). 

 And 5. Stem ard leaves of the Woodruffe {Aspcrnla odorata). 



C. L. Lamplugh. — There is no separate work that we are 

 aware of on the Sponges of the Yorkshire Coast. Get Gosse's 

 " Manual of Marine Zoology," which will answer your pur- 

 pose." (2) A new edition of Professor Phillip's " Geology of 

 Yorkshire " contains all that you require as to the coast sections. 

 It is published by Taylor and Francis at one guinea. (3) Pretty 

 much the same kind of the commoner fossil sponges will be 

 found in the Yorkshire chalk as in the chalk elsewhere in Eng- 

 land. (4) Your specimens from the Boulder clay are, No. i, Tel- 

 Una balthica, and No. 2, a fragment oi Pafwpca. You cannot 

 do better than make a collection of such marine shells from the 

 Boulder clays. Collectors of them are much in request. 



T. Richard.son. — The case of the "Cockroaches" you men- 

 tion is not one of albinism at all ; for all these insects, when 

 they first emerge from the pupa; state, are nearly white. In a 

 few days they assume their natural colour. 



Isaac Crawford. — Get the shilling work published by 

 Warne & Co., and written by Samuel Wood, called "The 

 British Bird Preserver." 



F. Quarterman. — The fossils you inquire about are as 

 follows -.—Astrea crassolantellata. Tertiary (a coral) ; Cyclocy- 

 at/uts Fittoni, Gault (a coral) ; Alveolai-ia semi-ovata. Lower 

 greensand (a Polyzoon) ; Niillipora, Lower greensand (a cal- 

 careous sea-weed, like existing species of ditto, and Corallina 

 officinalis); Tragos, Lower greensand (a sponge); Verticclli- 

 j>ora anastamosus (a Polyzoon?); Nebulipora pidchella, 

 Wenlock formation (a sponge '?).

 scopy " is published at Box 4875, New York City. Get
