HARDWICKE'S SCIENCE-GOSSIP. 



A. Shaw. — We do not undertake to name foreign specimens 

 of natural history. The objects shall be sought up and re- 

 turned to you. You will find Chenu's " Conchyliologie," of 

 help in naming your specimens. 



H. \V. S. \V. B. — The best diagrams for botanical class 

 lectures are those of Professor Henslow's (drawn by \V. Fitch), 

 issued, we believe, under the direction of the South Kensington 

 authorities.

 shells published by Messrs. Mardon, Son & Hall, of St. 

 Stephen Street, Bristol, compiled from Dr. J. Gwyn-Jeffreys' 

 " British Conchology," by Mr. H. K. Jordan, F.G.S. The 

 first part (1866), one shilling, contains all the land and fresh- 

 water species, and the marine as far as Littorinidae. The second 

 part (1870), one shilling and sixpence, from Rissoa to the end of 

 the work. No doubt the publishers would give Mr. Cockerell 

 information about it. — G. S. T.
