HA RD WICKE ' S SCIENCE-GOSSIP. 



To Dealers and Others. — We are always glad to treat 

 dealers in natural history objects on the same fair and general 

 ground as amateurs, in so far as the "exchanges" offered are 

 fair exchanges. But it is evident that, when their offers are 

 simply Disguised Advertisements, for the purpose of evading 

 the cost of advertising, an advantage is taken of our gratuitous 

 insertion of "exchanges," which cannot be tolerated. 



We request that all exchanges may be signed with name (or 

 initials) and full address at the end. 



Special Note. — There is a tendency on the part of some 

 exchangers to send more than one per^ month. W e only allow 

 this in the case of writers of papers. 



To our Recent Exchangers. — We are willing to be helpful 

 to our genuine naturalists, but we cannot further allow dis- 

 guised Exchanges like those which frequently come to us 

 to appear unless as advertisements. 



You cannot do better for your friend than get him Dr. Henri 

 Van Heurck's recently-published book, " The Microscope " 

 (London : Crosby Lockwood & Son), price, we believe, £2 2s., 

 noticed in the February number of Science-Gossip. 



E. H. Tugweli "Our Common Fossils and Where to 



Find them," originally appeared in Science-Gossip, spread 

 over a few years, but the volume under that name, since 

 published, is a very considerable enlargement of the articles 

 you refer to, with a great number of additional illustrations. 



P. 0. T. — We know no better manual for students com- 

 mencing the study of microscopic fungi than Dr. M. C. Cooke's 

 book on the subject, with coloured illustrations, which are 

 hardly required on account of the graphic descriptions now 

 published, we believe, by Messrs. W. H. Allen & Co., Waterloo 

 Place, London.

 Stormonth's "Manual of Scientific Terms," or Nuttall's
