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. ^_^__ 



C. H. Macer.— You will find all the eighteen specimens 

 of zoophytes you sent us to be named given in the " Answers " 

 column of Science Gossip for last January. We had mis- 

 placed the name, and so gave them under the head of " Zoo- 

 phytes." 



M. A. Tooke. — The insect is the well-known Water Scor- 

 pion (Nepa cinerea). 



Larvae on Hops. — The larva? found on hops, but which 

 afterwards refused to feed on them, are those of Orgyia 

 pudibunda, 



M. F. — Your specimens are as follow: 1, Crocallis elin. 

 guaria ; 2, in too bad a condition to make out; 3, Triphana 

 pronuba, male ; 4, a Polyzoan zoophyte, called Membranipora 

 pilosa. 



A. Pickard. — We are sorry to say your plants came to us 

 so thoroughly withered that we could not identify them. 

 They should have been pressed in blotting-paper. 



J. Fuller. — For instructions as to preparing skeletons of 

 leaves see article in the February number of Scibnce-Gossip 

 for J 872. 



' H. Gould. — Your fern is the Spleenwort (Asplenium adi- 

 antum nigrum). 



J. Boys. — Your plant is the Biting Persicaria {Polygonum 

 persicaria). 



M. Bailev. — Your plant is evidently the Common Mithri- 

 date Pepperwort (Lepidium campestre) ; but the specimen 

 came to hand so badly that it was difficult to make out. 



Y. Z. — The backs of the leaves are apparently covered 

 with the first stages in the development of some species of 

 "mould." 



J. G. H.-We should be glad to receive your paper. 



M. Murton. — You will see advice as to how to get rid 

 of " clothes "-moths in the last few Nos. of Science-Gossip. 



D. E. J. (St. David's). — Construct an aviary against the 

 south side of your garden wall, so that birds can fly within ; 

 or obtain the " artificial birds' nests " described in the 

 Animal World, to entice birds to nest in your garden. 2. The 

 " woolly substance " found on the Wild Rose is called 

 "Bedeguar," and is formed by a species of Cynips. 3. The 

 bird you mention is evidently the Water Ousel (Cinnlus 

 aquaticus). 



H. M. Hallidav.— The "spongy" fungus on oak-tree was 

 most probably Polyporus squamosum. 



T. C— The " minute shells" in flint are evidently those of 

 foraminifera, probably a Rotalina. Your zoophyte is Lepra- 

 Ha liyalina. 



M. — Your gault fossils are : — No. 1, Ammonites splendens ; 

 2, Ammonites planulatus ; 3, Ammonites lautus ; 4. portion of 

 flitto ; 5, natural cast of Pleurotomaria ; 6, fossil coral (Tro- 

 chocyathus) ; 7, Terebratula ; 8, portion of Turrilite. 



W. W. Kay. — Your specimens are the skeletons of the 

 hinder feet of a young badger {Meles tuxus). 



Dr. D. — With the exception of Pritchard's " Infusoria,'' we 

 know of no single work that will give the information 

 required. Smith's " Synopsis of the British Diatomacea? " 

 is the only English work that gives figures of all the British 

 ferns known at the time of publication (thirty years ago). 

 The figures and description of foreign species are scattered 

 through the Transactions of English and foreign societies.
