HARDWICKE'S SCIENCE-GOSSIP. 



C. PlTHER. — Soak the furniture well with common petro- 

 leum. The objects are undoubtedly eggs of some species of 

 mite. Sopping with petroleum is the most likely thing we 

 know to get rid of them. We shall be glad to hear if any of 

 our readers know of anything more inseciicidal. 



H. L. T. — SciENCK-GossiP has a large circulation outside 

 the United Kingdom — larger than that of any other scientific 

 journal. 



A. Flatters. — We have received your two excellent mounts 

 of transverse sections of Liliutn croceum, and leaf-bud of ash. 

 Both are very instructive specimens. 



John Cookson. — "The Naturalist's Gazette" was pub- 

 lished by Mr. Allen, 4 Ave Maria Lane, E.G., subs. id. 

 monthly. It is now united with "The Garner." 



R. M. W. — The worms are not the young of the common 

 earth-worm, but of the species known as " brandlings." 



H. G. Sadler. — Dr. Aveling's book will help you. 

 Messer's "New Method of Diagnosis" (Allen & Co., Water- 

 loo Place) will help you more. 



K. A. D. — We shall be pleased to have your paper. 



A Subscriber. — By some means your flower was not en- 

 closed. We have waited, thinking it had been inadvertently 

 left out. The best means of verifying grasses and sedges 

 would be to consult a herbarium at some museum ; or, failing 

 that, Sowerby's " Botany," at some free reference library. 



Rev. B. Whitelock and D. H. S. Stewart. — We are 

 much obliged for the abnormal examples of Geum and Salix 

 alba sent. They are very suggestive objects. 



G. E. M. — We frequently get applications for another 

 " General Index " of Science-Gossip, since the last issued in 

 1876. The expense, however, is too great unless we were 

 guaranteed a number. Although we are aware there is no 

 Cyclopaedia of Natural History in the world equal to the 

 twenty-five volumes of Science-Gossip, all purchasers do not 

 bind the volumes, and therefore a " General Index " hangs. 



H. E. Griset. — Stark's " British Mosses" (coloured plates), 

 price 7J. 6d.,&nd Dr. M. C. Cooke's "British Fungi" (coloured 

 plates), price 6s. < 



R. CouPAR. — Apply to Messrs. Macmillan for Professor 

 Marshall-Ward's book on the "Diseases of Timber." It is 

 published, we believe, in the " Nature Series," price 2s. 6d.
