HARDWICKE'S SCIENCE-GOSSIP. 



A. M. P. — In the Rev. J. G. Wood's recently published book 

 " Petland Revisited," you will find a chapter on Tame Chame- 

 leons, which will supply you with all the information you need. 



K. Ridings. — You will find it difficult to get a book on Marine 

 Conchology, with illustrations, at the price you name. There 

 is a nice little book, with plenty of woodcuts, by the Rev. 

 J. G. Wood, published bj' INIessRs. Warne at is., called " Com- 

 mon Shells of the Sea Shore." Get this first. 



T. S. K. — The gold-fish do not need much feeding. One 

 reason for their destruction in aquaria is over feeding. All 

 foods liable to ferment should be avoided. Small pearl bis- 

 cuits are best. One broken up now and then, say every month, 

 is sufficient. The vegetation induces hosts of Infusoria to 

 breed. Don't keep the fish in too bright a place. 



A. J. F. — Your grubs are the larvae of the stag beetle (/.«- 

 canus ccrvKs). Watering the ground with a solution of sulphate 

 of ammonia might get rid of them without injuring the plants. 

 You will get this solution from any chemist.
