HA RD WICKE'S SCIENCE- G OSS I P. 



Re-appearance of Plants. — I think a reason- 

 able solution to the mystery of the sudden appear- 

 ance of plants enumerated in your last issue by 

 J. E. C, may be that the species formerly grew in the 

 locality where the foundations of the houses were 

 dug, that by some cause buried beneath the soil, 

 their seeds lay dormant until being exposed, on a 

 favourable site, to light and air, they germinated. 

 I have noticed the same occurrence on newly-made 

 embankments and railway cuttings. — W. E. Windus, 

 Bexhill. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we new 

 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 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.
