HARDWICKE'S SCIENCE-GOSSIP. 



[June 1, 1870. 



NOTICES TO CORRESPONDENTS. 



C. E. M.— Why not read the previous correspondence on 

 the subject before writing about it ? 



J. A., J. P.— Please to read the notice at the head of " Ex- 

 change" column. If our instructions are not regarded, we 

 shall reluctantly be compelled to exclude all " Exchanges " 

 not in proper form. It is a careless habit not to write generic 

 names in full, against which we constantly protest. 



M. S. W.— Only the natural stalked glands of the leaf. 



J. E. — Contributions may be considered as declined if they 

 do not appear within two or three months. 



W. H. J.—Pucci)iia Betonictz. 



W. B. F.— We do not think that they exceed 30 inches in 

 expanse, usually less. 



J. H. — The fly is Bombylius medius, L.; order Diptera ; 

 family Bombylides. It is analogous to the humming-bird in 

 its flight, and in its habit of sucking flowers while on the 

 wing. — F. W. 



E. W.— Probably the common larch, but there is not suffi- 

 cient evidence to decide. 



T. S. W.— Cooke's " Manual of Structural Botany " (Hard- 

 wicke) ; Stark's "British Mosses" (Routledge); Page's 

 " Handbook of Geology." 



J. S.— They are not so thin as they should be to make good 

 slides. 



R. R. — We certainly do object to name two or three mosses 

 for the same person month after month ; and we cannot at- 

 tempt to name any without fruit, which is the condition of 

 all three of your specimens. 



E. W.— The male fern Lastrea fillr-mns. Clean fish-scales 

 by well washing, and mount dry or in balsam. 



J. B. R. — A species of Lfpisma, probably L. saceharina. 



S. A. B. — We do not attempt to name ferns from barren 

 fronds. 



H. K. O.— The "vinegar plant" is the mycelium of a 

 fungus, which, when perfect, is Penicillium crustuceum. The 

 " Balsam Poplar " is Populus balsamifera, natural order Sali- 

 cacece. 



J. F. seriously inquires if any one can send him the root of 

 the "Mandrake"; as the omnibus conductor says: "Will 

 any gentleman oblige a lady ? " 



A. J. M. A. — You should first have consulted a book on 

 British birds, such as Macgillivray's or Yarrell's. We do not 

 profess to illustrate the common habits of animals which have 

 been written about over and over again. 



H. W. G. — Aulacomnium androgy/ium. — R. B. 



J. C. D. — No. 1. Anumodon viticulosus. 2. Hypnum veluti- 

 num. — R. B.

S. A. S. — Racomitrium Sudeticum. The leaf points are 

 hoary. Will you kindly send a little more ?— R. B. 



A. J. — No. 1. — Timnia Norvegicn, Zetterstedt ; regarded as 

 a variety of T. megupolitana. 2. Hypnum piliferum. Please 

 to forward a few more specimens of No. 1, and the locality.— 

 R.B. 



E. C. J. — No. 1. Arthronia astroidai, Ach.— W. C.
