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. 



Fresh Chara. — A correspondent asks our good offices to 

 obtain for him "a little fresh Chara." Will our botanical 

 friends, who can obtain it, send us a small supply ? 



W. Patrick. — You can purchase Anodotis of R. Damon, 

 F.G.S., Weymouth. 



A. F. Fischer. — You cannot do better than preserve the 

 chrysalis in the earth of a flower-pot. Put the latter out of 

 doors. It will soon cease " wriggling." Out of doors is their 

 natural condition of hybernation. 



W. H. Legge.— The caterpillar of which you sent us a 

 coloured drawing, is that of the well-known Pale Tussock-moth. 

 The caterpillar goes by the name of the " Hop-dog" (prgyia 

 jntdibvnda). 



Y.. M. (baddleworth).- — The specimens sent us from the turf- 

 pits are flint chips, and seem to us to be the result of human 

 handiwork. This appears all the more probable from the fact 

 that flint is a very rare mineral, even in the drift beds, in 

 your district. Can you send us some larger specimens for 

 inspection ? 



W. H. S. (Colchester). — We shall feel obliged if you will 

 send us some of the insects which demolish the " black beetles," 

 as we cannot identify them from your description. 



W. S. Wakefield. — The plant sent us is Veronica Hen- 

 dersonii. 



F. Coleman. — We have heard of no other instance of non- 

 fulfilment except your own. 



J. A. Sandkokd (Ohio). — Accept our thanks for specimens of 

 AJ>ocy>ium androsamiifolnim, 



C. W. H. — There is no fear whatever of the ants doing your 

 Deodaras any harm. 



Colonel M. — You had best have Science-Gossip sent to 

 you direct from the publishers. The small crystals are car- 

 bonate of lime, 



F. R. B. — We cannot, of course, tell you the name of the 

 species of mussel without seeing specimens. But there is no 

 doubt that the deposit in question is a post-glacial one, of the 

 same age as our raised beeches. 



F. Q. — You had best consult Whitaker's "Geology of the 

 London Basin," published by Her Majesty's Stationery Office, 

 for details of and references to the various sections of the 

 Woolwich beds exhibited in the neighbourhood of London. 



S. C. M. — Sach's " Botany," translated and edited by A. W. 

 Bennett and Professor Dyer, and published by the Clarendon 

 Press, gives the best account of the laws of vegetable growth 

 and development. 



A. M. (Wandsworth). — The crustacean, of which you sent us 

 a drawing is Idotca tricuspidata. 



J. Ransom.— We have no doubt that Mr. Bartlett, the 

 Superintendent of the Zoological Gardens, would give you all 

 the necessary information respecting the management of 

 Marmosets. 



T. C. M.— -We have referred to the MS. of your " Exchange " 

 in the January number, and find that we printed it exactly as 

 you wrote it ! 



R. T. Andrews. — The "glass-like substance" you sent us 

 is Selenite, or crystallized sulphate of lime ; very likely from 

 the London Clay formation. 



J. Cunnack. — Your written description of the Hawk answers 

 best to that of the common Buzzard (Puteo vulgaris). 



W. K. and Others. — Your specimens have been forwarded 

 to competent authorities to be named, and their names will 

 appear in these columns as soon as we have received them. 



E. R. F. — Potton, in Bedfordshire, is situated on the Lower 

 Greensand formation, and the fossils you mention are, no 

 doubt, from that deposit. 



W. B. wishes for the address of the South London Ento- 

 mological Society, as it has removed from its old quarters. We 

 shall always be glad to chronicle such changes of removal. 



C. Harris. — Many thanks for the specimens, which are very 

 interesting. But we cannot undertake to name zoophytes from 

 the Cape of Good Hope, or any other place where the fauna has 

 not been scientifically worked and described.
