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 8th of each 

 month. 



F. E. S.— The specimen sent is a myriapod, not uncommon 

 on damp hedge-banks, called Gcophilus electricui. It has no 

 relation whatever with the glow-worm. 



j s a.— Get Frank Buckland's work published by the 

 Christian Knowledge Society, entitled " Familiar History of 

 British Fishes," price about 5s. 



P. H. G.— Many thanks for your kindly interest. The sug- 

 gestion shall be attended to. 



G B. W.— See a note in the June No. of Science-Gossip, 

 page 139, headed "To Clean Corals." That will give you the 

 information you require. ,..,„_ 



R. C— It is very certain that the live frogs got into the 

 " cavity of the stone " by some means, although " no crevice 

 or fissure could be found," and equally certain that the live 

 frogs have not been hybernating there since the carboniferous 

 period, millions of years ago ! We have seen several in- 

 stances of "live frogs and toads" having been lound in 

 " solid rock," but every examination proved they had crept 

 there to hybernatij. 



C. S. K.— You will obtain all the information you require 

 by addressing Mr. E. Newman, 9, Devonshire-street, Bishops- 

 gate. 



G. G.— It is not an unusual thing to see dipterous flies and 

 even wasps sipping the dregs or "heel-taps" of wine-glasses. 



J. p. s.— The specimen is a variety of the common Haw- 

 thorn (Crataegus oxyticantha), having extraordinary large 

 berries. 



F. Coles.— The minute red fungi on the bark of the twig 

 sent are a species of Spharia. 



W. H. B.— Get Mr. W B. Hughes's little book on " The 

 Management of the Marine Aquarium." (London: Van 

 Voorst). You will there find, on page 34, how to prepare 

 artificial sea-water. 



r s. T.-We have not heard that spiders are fond of the 

 berries of the yew. Wasps have a particular liking for them, 

 and their sweetness probably attracts many species of fruit- 

 feeding flies. ' . 



W. J. B. and W. K. H.— Thanks for your kindly sugges- 

 tions. 



Bats.— Any reader of Science-Gossip, knowing any haunts 

 (caverns or otherwise) of bats will oblige by communicating 

 with " H. L.," care of the editor of Science-Gossip, 192, 

 Piccadilly, London. 



John Turner.— The specimens forwarded in a bottle seem 

 to be, as regards the pteropod, most nearly allied to Limacina 

 antarctica, but coming from Davis Straits, in the arctic regions, 

 we should not expect it to be the same species. The shell 

 soon drops off in L. antarctica. The Crustacean is an Am- 

 p/iipod, and seems to be a species of Gammarus. 



W. H.— We do not think Dr. Carpenter's Lecture to the 

 working men of Bristol during the meeting of the British 

 Association, on " A Piece of Limestone," has been published, 

 except in the Bristol newspapers during the above occasion. 



Zoophytes.— The packet of eighteen different kinds of 

 Zoophytes, &c, sent to be named some time ago, are as 

 follows: — No. 1. Salicornaria farcimmoides ; 2. Sertularia 

 urgentea; 3, 11, and 4. Sertularia abietina with Spirorbis 

 nautiloides and Sertularia rosacea; 6. Sertularia cupressina; 

 6. Antennularia antennina ; 7- Antennularia ramosa ; 8, 13, 

 and 10. Flustra truncata; 9. Cellularia reptans; 12. Crisia 

 eburnea; 14. Membranipora pilosa ; 15. Membranipora pilosa, 

 Eucratea chelata, and Leporalia annulata; 16. Sertularia 

 pumila; 17. Cellularia avicularia ; 18. Leporalia trispinosa.
