HARDWICKE'S SC I E N C E - R O SSI P. 



NOTICES TO CORRESPONDENTS. 



F. J.— The occurrence of vegretable remains in the chalk is 

 exceednigly rare, and generally limited to fragments of wood. 

 We have no doubt whatever that your supposed " seaweeds," 

 in flint (of which you send a sketch), are the dendritic mark- 

 ings of oxide of manganese. They are of common occurrence 

 in cracked flints, as well as on the suifices of the cracks in 

 the harder chalk. 



J. I-.— See an article in Srii-vcuGossip for February, 1872. 

 on " How to Prepare Skeleton Leaves." It will give you all 

 the information you require. 



R. n., jun., reads us an editorial lesson on our remissness 

 in not inserting his own communications. We assure him 

 we shfiU be very glad to do so, when we get anything wnrth 

 inserting. Our space obliges to defer many paragraphs we 

 vrould like to publish. 



Naming Plants. — We have received from " Bfiss H." a 

 packet of above '20 species of plants to be named, some of 

 them of the commonest forms. This is rather a vthaletale 

 attack upon editorial labour and patience, but place au:i 

 dames ! 



C. — Your specimen of microscopic fungus on the leaves of 

 the Bo.\ is Pucctjiiu /-u.»(. See Cooke's " Handbook of British 

 Fungi," No. 1514. Can you forward us a specimen? 



F. Barnard. — The specimens inclosed, of the groundsel 

 leaves from Australia, are attacked by variety d of ^^icidium 

 compositarum. Bee Cooke's " Handbook," No. \6H. 



J. W. RussBLL. — The fossils are rather obscure, but those 

 on the fragment of rock from Hastings appear to be Cyrena 

 media, a common W^ealden fossU. The chalk fossil from East- 

 bourne is only part of the impression of an ammonite. 



C. J. W. — Iron-ore is not found in the Sussex chalk, that 

 we are aware of, except, perhaps, as detached nodules of iron 

 sulphite. A good elementary Mineralogy is published by 

 Lockwood & Co. (Weale's series), at a low price ; but your 

 best plan would be to get Dana's " Student's Manual of 

 Mineralogy." 



Sub. — Perhaps you are not aware of our rule not to answer 

 anonymous queries. W'e are obliged to adhere to this ; and 

 if you will put your query in the ordinary way, we shall bo 

 glad to answer it. 



P. A. — We cannot undertake to return the specimens sen* 

 us to be named. They have frequently to pass from us to 

 more competent judges, and we cannot guarantee their safety 

 from accident or being mislaid. Those of our querists who 

 have to await replies, must remember that we are obliged to 

 consult the leisure of those gentlemen who are good enough 

 to answer queries or name specimens. 



T. Orams. — The Hibincus lUiflorus is a native of Bourbon, 

 and was first introduced into this country in 1822. 



W. S. E. — See a capital article in the Popular Science 

 Review for January last, by the Rev. T. R. Stebbingg, entitled 

 '• What are we to believe in Science — Teleology or Evolu- 

 tion?" 



T. DvER. — The word Octopua should be accented on the 

 first syllable — the practice of accenting it on the second is 

 bad, and has no grammatical warrant. We do not see why 

 you should not speak of this animal in the plural as " Octo- 

 puses." It is now thoroughly anglicised, and to use the 

 plural " Octopuses " is as correct as to say " Elephants," or 

 " Rhinoceroses." 



T. R.— Cooke's " Handbook of British Fungi " is the best 

 and most e.xhaustive of its kind published in any country. 

 We know of no other introduction to the study of micro- 

 scopic fungi than the work by the same author, published by 

 Hardwicke, Piccadilly. 



H. A. M.— 1. The publisher of Gw5-n Jeffrey's "British 

 Conchology" is Van Voorst, Paternoster-row, London. It is 

 in five vols. 2. You had better apply to the Hon. Sec. of the 

 Folkestone Natural. History Society concerning their " Guide 

 to the Natural History of the Neighbourhood," and its price. 

 Or perhaps some of our readers will take tho hint, and send 

 usvthe information. 



J. Groves. — For information respecting the Botanical 

 Exchange Club, apply to H. C. Watson, Escj., Thames Dilton. 



H. S. RiCHARusoN. — You will find an account both of the 

 Glass-rope sponge (il^aiowema), and investing I'olythoa, in an 

 article by Mr. F. Kitton, which appeared in Scik.vck-Gossip 

 for February, 18/2.
