HARDWICKE' S SCIENCE-GOSSIP. 



E. E. Evans. — For details concerning the construction of an 

 Egg Cabinet see " Notes on Collecting and Preserving Natural 

 History Objects," price 3s. 6d., published by Hardwicke & 

 Bogue. 



K. D. (Almondsbury). — Orbitoliiia. is a genus of fora- 

 7/iiui/crir.

 you enclosed has reverted to the condition of a true leaf.

 bv Dr. Lankester, with chapter on the " Polarisation of Light," 

 by F. Kitton, published at 4s. by Hardwicke & Bogue, 192, 

 Piccadilly, London. 



A. Smith. — Get Cooke's " Microscopic Fungi," (illustrated) 

 price 6s. London : Hardwicke & Bogue, 192, Piccadilly. 



K. D. — Bentham's " Handbook of the British Flora," pub- 

 lished by L Reeve & Co. ; and the Second Edition of 

 " Hooker's Student's Flora of Great Britain," just out, pub- 

 lished by Macmillan. 



R. Rattray. — Many thanks for your excellently mounted 

 slide of Licmophora flabellata. 



M. Shaw. — Accept our thanks for seedlings of the Date 

 Palm. 



W. H. Shrubsole. — "Banded-flints" were originally 

 formed by the filling-up of cavities in nodules, layer by layer. 

 Subsequently the nodules have been broken up, and the harder 

 banded parts liberated, and rolled into the shapes and appear- 

 ance in which you see them. (2). The boring appears to have 

 been made by some other mollusc than Teredo. (3). No doubt 

 the concretionary nodules, and the appearances you describe, 

 are due to the soft, decomposing, organic matter of the animals 

 whose hard parts usually form the nuclei, having caused 

 chemical segregation. 



To Querists. — We are obliged to postpone the publication 

 of several answers until our next, on account of want of space.
