HARDWICKE'S SCIENCE-GOSSIP. 



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 9th of the 

 previous month. 



Science Gossip Botanical Exchange Club. — In our 

 last number we prematurely stated that all the parcels had been 

 made up and sent out in connection with the above club. The 

 majority of them have been delivered, but there still remain 

 others, which will be forwarded as soon as possible. The work 

 of arrangement and exchange has been enormous, and we must 

 beg those members who have not yet received parcels to enter- 

 tain a little patience. We feel certain that the result will 

 satisfy all parties. 



J. Bramhall. — It is not at all meditated to bring out a 

 second edition of Blackwall's " Spiders " at present. We are 

 not aware whether Messrs. Douglas & Scott have yet pub- 

 lished their monograph on British Homoptera. 



S. T.— Get the "Collector's Handy Book," price 2s. 6d., 

 published by Hardwicke & Bogue, 192, Piccadilly. You will 

 there find full instructions as to mounting microscopic objects. 

 The best way of preserving animal bones is to steep them in 

 gelatine, or boil them in a solution of glue. 



F. H. L. —The "coral-like substance" you sent us from 

 Falmouth beach is not a coral but a lime-secreting sea-weed, 

 called by Harvey Melobesia fasciculata. It is allied to the 

 common Corallina officinalis. 



E. Edwards. — Many thanks for your good wishes. You 

 had best procure Robson's book of " Botanical Labels" from 

 Messrs. Hardwicke & Bogue, and paste each label on the 

 species. 



W. K. (Leeds). — We know of no better way of hermetically 

 sealing specimens in bottles containing spirits than the old- 

 fashioned one of covering the outside of the cork with a layer 

 of melted sealing-wax. 



K. A. Deakin. — The Palaeontographical Society have 

 published the fossils of nearly every British formation, and 

 these are contained in about thirty large volumes. By applying 

 to the secretary, Rev. T. Wiltshire, Lewisham, we have no 

 doubt you could obtain a list of all the society's publications. 

 You can get the implements you speak of at any large natural- 

 history dealer's. 



J. H. Morton. — There is no possible danger of being 

 bitten by the slowworm (A nguis fragilis). 



S. T. — For stocking small aquaria see instructions con- 

 tained in "The Aquarium, its Structure and Management," 

 published by Hardwicke & Bogue, 192, Piccadilly. 



J. D. O.— Get S. Wood's shilling book on "The British 

 Bird Preserver," published by Warne & Co. 



A. Michael. — Your desmid is Closterinm setaceum (in con- 

 jugation). 



J. R. James. — Many thanks for your kindly suggestions, 

 they will not be unheeded.
