HA RD WICKE'S SCIENCE- G OSSIP. 



A. J. Adams.— Obtain Dulau's Catalogue of Works, &c., 

 on Geology, just published, 37 Soho Square, London, W. 



H. E. Griset. — Get Bausch's "Manipulation of the Micro- 

 scope" from W. P. Collins, 157 Great Portland Street, 

 London, W. 



J. K • — The lichens are correctly named. 



C. L. R.— You had best advertise in Science-Gossip. 



A. J. Shaw. — We were at a loss for some time to identify 

 the ''green bags," found on the sea-shore. We have tracked 

 them down. They are the outer skins of green melons which 

 have been in ^ea-water some time, so that all the interior pulp 

 has been dissolved out, and only the external hardy pericarp 

 lei't as an empty "green bag." The microscope sho*s the 

 characteristic hairs. 



W. Wilson. — The "Science Made Easy" was published by 

 D. Bogue. You can get copies, we believe, of Messrs. W. H. 

 Allen & Co., Waterloo Place.
