 same year ? We gathered several flowers on

 ripening fruit. — N. P. Chrzastow, Poland. 



[P.S. — See the paper on the " Development of a 

 Flea's Egg " (with copious illustrations), in November 

 No. of Science-Gossip, 1885.— Ed. S.-G.] 



The "Wandering Jew." — Can any of your 

 Canadian readers give the botanical name of the 

 creeping plant known locally as " Wandering Jew " ? 

 It is found in the North-West Provinces, particularly, 

 I believe, in Manitoba. — John Christie.

NOTICES TO CORRESPONDENTS. 



A. B.— The eggs reached us in a very shrivelled and dried- 

 up condition. They appear to be those of the common Earth- 

 worm. 



Marv E. — Yoii had best apply to the secretary of the 

 Entomological Society for information about Miss Ormerod's 

 paper on Preserving fruit from Caterpillars. 



To Correspondents and Exchangers. — As we now 

 publish Science-Gossip earlier than formerly, we cannot un- 

 dertake to insert in the following number any communications 

 which reach us later than the 8th of the previous month. 



To Anonymous Querists. — We must adhere to our rule of 

 not noticing queries which do not bear the writers' names. 



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 oflfers are simply 

 Disguised Advertisements, forthepurposeof evading the cost 

 of advertising, an advantage is taken o( onr 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. We only allow 

 this in the case of writers of papers. 



Lost, or arrested in transit, the botanical circulating maga- 

 zine, " Sachsiana." Any member having it in his possession 

 will please forward it to J. Hamson, Bedford. 



B. B. Le T.— We have looked through all the late Frank 

 Buckland's works, but cannot find any account of the " Beavers 

 of Bute." Perhaps it appeared in " Land and Water," or some 

 of our correspondents may be able to inform you. 



A. Verindek. — We have not heard who is editing the new 

 edition of " Carpenter on the Microscope." The coloured 

 plate of Foraminifera appeared in the September number of 

 Science-Gossip vol. for 1885. 



W. J. L.— The desirability of publishing another "General 

 Classified Index" to the vols, of Science-Gossip is under 

 consideration for the end of the present year, when we shall 

 have completed the 25th vol., and hope to celebrate our 

 " Silver Wedding ! " 



A. Mavfield. — Lastrea multijlora does not exist as a 

 British species of fern. We believe it was a name given to a 

 variety by Newman, but which does not appear to have been 

 generally adopted. 



J. C.— The fossil is Ammonites cati7iatus. The fragment 

 of stone is a partially metamorphosed volcanic ash. 



B. D. P. — Your second paper shall appear in due course. 

 W. H. Thrush. — A Queen Elizabeth's shilling varies in 



value from two to iive shillings, and a sixpence from one to two 

 shillings, according to condition. 



A. G. Hammond. — Is your account of the Fossil Hunt 

 illustrated 1 Send it on.
