HARDWICKE'S SCIENCE-GOSSIP. 



NOTICES TO CORRESPONDENTS. 



We must remind our friends, who make use of this column 

 that the following: rules should be strictly adhered to : — 

 First. That perfect specimens be sent. Secondly. That all 

 the information as to habitat, &c., that the inquirer can give 

 should be forwarded with them. Thirdly. To bear in mind 

 that drawings, unless very perfectly executed, are useless, 

 and a tyro is very apt to omit some distinctive characteristic 

 which would enable the examiner to decide the genus and 

 species of the object sent. Lastly. Never to send an object 

 for identification until the inquirer has used his best endea- 

 vours to find out for himself all the information he requires. 

 Questions are very frequently sent, which the slightest effort 

 on the part of querist in looking through some elementary 

 treatise would have given all the knowledge required. 



F. W. S. — Your specimen is the Bladder Fern {Cystopteris 

 fragilis) . not uncommon in mountain limestone districts. We 

 have frequently seen it growing in your neighbourhood. 



S. W. M.— Will you be good enough to send us your address ? 

 By some means it was left out by the compositors at the last 

 moment. 



T. AV. — Your specimen is the spreading silky Bent-grass 

 (. Agrostis spicaventi) . 



A. Allen. — Thanks for the slide. There can be no doubt 

 you have succeeded in unproving the preparation. 



Jamks C. — Gymnngramma sulphurea is a Jamaican fern, 

 and was introduced into this country in 1808. 



E. S. Pbtre. — Your specimen arrived in a high state of 

 decomposition. You should have sprinkled it with carbolic 

 acid before sending it. It is the Long-eared Bat {Plecutus 

 tiuritus). 



W. Wakefield. — The book that will, we think, meet your 

 requirements is " Half-hours in the Green Lanes," just pub- 

 lished. 



Henry B. — Your grass is the Bearded Darnel (Lo^JM/n <e)»M- 

 lentum), and a dangerous species. 



Jambs Jackson. — We do not know of such an agent as 

 the person you name. 



T. W. R. — Castleton, in the Peak district, is one of the 

 best places we know of for collecting mountain limestone 

 snecimens. Salt Hill, near Clitheroe, in Lancashire, is another 

 good locality. 



Frank Durgiian. — Yours was an advertisement, not an 

 e.rclninge, and therefore ineligible for the latter column. 

 Apply to Publisher for terms. The cheapest way would be 

 to get a cabinet made. For pattern see article on " Collecting 

 and Preserving Birds' Eggs," in the April No. of Science- 

 Gossip for 18/2. 



F. Allen.— You may obtain the tin tubes from Messrs. 

 Rowney or any other artist's colourman in London. Will 

 not the collapsible tin tubes sold by any perfumer at a very 

 cheap rate answer your purpose? 



G. F. — Your slide reached us safely. Please accept our 

 thanks for it. Answer next month, all being well. 



F. H. Cass. — You will find the best advice we know, of 

 how to prepare skeleton leaves, in an article on that subject 

 published in the February No. of Sciknce-Gossip for 18/3. 



Alliari.a.. — The book you mention is the one to which wc 

 referred. Also, procure Mrs. Lankester's "Wild Flowers 

 worth Notice"(London, Hardwicke), with coloured plates. You 

 will gain a much better knowledge of botany by working out 

 the common species for yourself than by getting them named 

 for you. After all, the mere knowledge of the names of 

 plants is but a poor botany ! The specimens sent are — 1, Char- 

 lock (Shiapis arvensis) ; 2, Rest-harrow {Ononis arvensis) ; 3, 

 Common Hedge-mustard (Slsynibrium officinale) ; 4, Corn 

 Chamomile {Anthemis arvensis) ; 5, Wood spurge (Euphorbia 

 antygdnloides) ; 6, Hedge Wound-wort {Stachys sylvatica).
