HARDWICKE'S SCIENCE-GOSSIP. 



fJuNE 1, 1SG9. 



NOTICES TO CORRESPONDENTS. 



W. S. and J. J.— Must not send so many mosses again, as 

 we cannot name "by the lump." 



M. G. F. — The common snake (Tropxdonotus natrix) : feed 

 it on little frogs. 



W. E.— Triihner & Co., Paternoster Row, London. "The 

 Dental Register " is three dollars per annum. 



E. H. K. — Had you been, a " constant reader " of Sciencb- 

 Gossip you would have seen the numerous recent communi- 

 cations on this subject. 



Erratum (see p. 1G9).— "Large Egg." The length should 

 have been 3^ and not 3f, as stated. 



H. C. S. — Nothing novel. 



W. H. D.— We really cannot reopen the discussion. Your 

 anecdote is not more conclusive than many others on 

 record. 



W. A. F.— Eggs of the moths named maybe obtained of 

 Dr. A. Wallace, Colchester, Essex. 



W. H. J. — No. 1, Coleospurium pingue. No. 2, Uredo 

 potentillarum on Burnet. 



W. H.— All the entomologists to whom your drawing has 

 been submitted regard it as a variety of P. alexis. 



C. s.— We find that experienced entomologists agree in re- 

 garding your (supposed) new species as only a variety of 

 Strenia clathrata. 



H. F. M.— Cockroaches are what are called " black 

 beetles," although not beetles at all. 



F. R. M.— No. 1 is possibly Davallia (Leucostegia) eliw- 

 mphylla, Wallich ; but we cannot say with certainty, as there 

 is neither fruit nor rhizome. — J. G. B. 



W. H. D.— We do not remember such a bnok. 



J. B. K.— It is not uncommon for parrots to lay eggs in 

 captivity in this country. 



R. H.— The small round worm found in the intestinal canal 

 of the Whiting (Merlangus vulgaris) is a full-grown female 

 example of the Asearis clavata of Rudolphi. This parasite 

 infests the Gadidre generally. — S. C. 



E. H. — 1. Many species of grasshopper are " common." 

 We cannot reply to so inexact a question. 2. In America at 

 least three species of moths have larvce, called "army- 

 worms," i. e., Anomis xplina and Leucania miipuneta, both 

 belonging to the Noctuidce ; and Clisiocampa sylratica, 

 belonging to the Bomhyr.idae. I believe the German "heer- 

 worm '" is the larva of Bmnbyx proressionin. — R. Mc L. 



R. G. — Certainly not a lichen ; at present we fail to discover 

 what it is. 



F. S. — (l) Cover with powdered lime and expose to the air. 

 (2) Dip them in benzole. — F. M. 



B. C. — The larva found in the pear-tree is doubtless that of 

 a moth, Zeuzera ccsculi. — F. M. 



J. W. L.— Your plant is Wild Garlic, or Ramson's Allium 

 ursinum. In forwarding specimens for identification, an 

 entire plant, or, at the least, leaves and flowers, should be 

 sent.— B. 



Y. Z. Z.— We only undertake to conduct exchanges for 

 foreign correspondents. Your own address must be 

 inserted. 



J. W. L.— Your " exchange " is too long. 



J. W. W. — We have often found the fungus Ustilago re- 

 ceptaculorum filling the involucres of goatsbeard. Others 

 affect species of polygonum, the anthers of Lychnis, &c. — 

 See " Microscopic Fungi," p. 82, pi. v., fig. 92. 



J. J. — 1. Hypnum pnelongum. 2. Bryum crespiticium. 

 4. Mnium hornum. 5. Tetraphis pellucida. 6. Hypnum 

 prselongum. — R. D. 



W. S. — 1. Fissidens bryoides. 2. Ceratodon purpureus. 

 3. Hypnum rivulare. 4. Ceratodon purpureus. 5. Weisia 

 controversa. 6. Plagiotherium sylvaticum. — R. B. 



T. H. — 1. Hypnum cuspidatum. 2. II. rivulare. 3, 4. 

 II. Swartzii.— R. B. 



R. G. — 1. Dicranum fuscescens. 2. D. scoparium (3 

 orthophyllum. 3. Antitrichia curtipendula. 4. Bryum inter- 

 medium. — R. B.
