HA RD JVICA'E'S SCIENCE- G OSSIP. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we now 

 publish Science-Gossip earlier than formerly, we cannot un- 

 dertake to insert in the following number any communications 

 which reach us later than the 8th of the previous month. 



To Anonymous Querists. — We must adhere to our rule of 

 not noticing queries which do not bear the writers' names. 



To Dealers and others. — We are always glad to treat 

 dealers in natural history objects on the same fair and general 

 ground as amateurs, in so far as the "exchanges" offered are fair 

 exchanges. But it is evident that, when their offers are simply 

 disguised advertisements, for the purpose of evading the cost of 

 advertising, an advantage is taken of our gratuitous insertion of 

 " exchanges " which cannot be tolerated. 



We request that all exchanges may be signed with name (or 

 initials) and full address at the end. 



G. R. Hyatt. — The objects you sent are the larva of the 

 common drone-fly [Eristalis tenax), and one generally known 

 as "rat-tailed maggots." The tail is telescopic, and is the 

 breathing-organ. It makes a capital microscopic object. 



D. Packer. — No communication from you has yet reached 

 us. 



T. Winder. — Many thanks for the neatly-mounted specimen 

 of parasite. 



F. Bedloes. — You will find a series of capital articles on 

 staining vegetable sections in the back vols, of Science-Gossip. 

 The vols, of Cole's "Studies in Microscopical Science" contain 

 some first-class pages on Vegetable histology, staining, etc. 

 For a text-book, however, you cannot get a better book than 

 the last edition of Sachs. 



M. Rae. — The specimen is the marsh helleborine [Epipactis 

 palustris). 



F. Ramsbottom. — The objects sent are the bird's-nest fungus 

 [Cyathus striatui). See Cooke's " Liriti=h Fungi," vol. i., 

 p. 409. 



J. G. — The special number of Science-Gossip devoted to the 

 British Hepaticae is now, we believe, out of print. Apply to 

 some good secondhand scientific bookseller for it. 



E. C. Cottingham. — Your specimen is the hair worm (Gor- 

 diits aquaticus). You will find, a full account of its life-history 

 in Science-Gossip for the year 1865, pp. 107 and 197. 



S. Howarth (Sheffield). — The specimen is undoubtedly a 

 species of .bird tick, but we have not yet made out the species. 

 We will reply later on. 



W. R. Head (Chicago).— You may obtain fossil sponges 

 from Mr. J. D. Russell, 78 Newgate Street, London, or Mr. 

 Samuel Henson, 277 Strand, London.
