HARDWICKE'S SCIENCE-GOSSIP. 



D. Packer. — Please write to Mr. John Browning, F.R.A.S., 

 63 Strand, London. He will doubtless give you all information 

 you require for the construction of a Dyalite telescope. 



C. F. C. — Kircaldy is on the lower coal measures, and the 

 strata are full of fossil p'ants. We hardly think your fossil will 

 be a sea-weed ; it is much more likely to be a fragment of some 

 carboniferous land plant, such as a flattened calamite. 



W. Duncan. — The material which goes by the name of 

 "Russ" among fishermen is the remains of a fine-tubed sea- 

 worm, Filograna implexa. The polyzoon on shell of Modiolus 

 is Lcpralia coccinea.

 published by Lovell Reeve at 10s. 6d. ; may get a secondhand

W. Hambkough. — We received a box-lid with the post-office 

 remark "found without contents," which, from the hand- 

 writing, we suspect must have belonged to your box.
