HARDWJCKE'S SCIENCE-GOSSIP. 



71 



years back being at Tintagel, weather Ijound, and 

 having nothing to read but a Black's "Guide to the 

 South Coast,'' date 1S72 which was tlie whole of the 

 coffee-room literature, he came across the following 

 choice natural history information, p. 114. "To- 

 wards Babbicombe the botanist will meet with 

 Actinia crassicornis, Actinia nivea and Actinia mcscm- 

 bryanthcmnm, Toriida tortiosa and didymurn, Rhody- 

 menia palmata, Laminaria digitata and sacharina, 

 Laurentia pinnatifida and Plocaminm coccincuni. 

 Along the beach towards Paignton the geologist may 

 look for Echinus iniliaris, TrocJms ziziphiniits, 

 Asterina gibbosa, Doris pilosa, PJiolus parua, Pliolus 

 dactyliis ^xid Antlica cerciisi" Whatever may be the 

 accuracy of the information, it is certainly a little 

 mixed.— ?r. T. Suffolk, F.R.M.S. 



Dried Flowers with Colours. — In answer to 

 Mr. T. McGann's communication, I beg to state that 

 he may find worthy information on the subject he 

 seeks in Mr. English's admirable " Manual on the 

 Preservation of the Larger Fungi and Wild Flowers," 

 published by A. B. Davis, High Street, Epping, at 

 half-a-crown. — J. W. Williams, B.Sc. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers.^ As we now 

 publish Science-Gossip earlier than heretofore, we cannot 

 possibly insert in the following number any communications 

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



To Anonymous Querists. — We receive so many queries 

 which do not bear the writers' names that we are forced to 

 adhere to our rule of not noticing them. 



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 oi onx 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. 



O. J. H. — We have no doubt the object you saw in the grass 

 was not an uncommon species of phosphorescent millipede, 

 called Geophiliis electricits. 



T. Richardson. — Your specimen is the Lancashire Asphodel 

 [Narthcchitn ossijragnin) in the seeding condition. 



S. A. B. — It is intended that our coloured plates shall deal 

 with subjects calculated to please every class of readers, zoolo- 

 gical and botanical, as we hope you will see in future numbers. 

 Thanks for the suggestion. 



W. H. G. — A lengthy and well-illustrated paper on " The 

 Galls of Essex," giving an account of all the commoner galls 

 and the insects which produce them, will be found in the 

 "Transactions of the Epping Forest, &c., Field Club." It is by 

 Mr. E. A. Fitch, the well-known entomologist, it occurs in 

 Part 6, vol. ii., and may be obtained from the club, Buckhurst 

 Hill, Essex. 



John Smith. — The best table we know of the Animal King- 

 dom, showing the most recently accepted arrangement of 

 classes, orders, families, &c. in the fullest manner, is Mr. 

 Francis P. Pascoe's "Zoological Classification." A handy 

 book of reference, with the tables of the sub-kingdoms, classes, 

 orders, &c., of the animal kingdom, their characters and lists 

 of the families and principal genera. Published by Van 

 Voorst, at 105. dd. 



W. E. Ward. — The "Ornithologist and Oologist " is an 

 American journal, published by F. B. Webster, Pautucket, 

 R.I. The subscription (including postage) is 5^. per annum. 

 You may obtain it of Mr. A. Cliff, 35 Osborne Road, Forest 

 Gate, Essex. 



J. A. J. — Apply to James Gardner, 29, Oxford Street, London, 

 for Doubleday's " Classification of Insects." 



J. S. Hutchinson. — In base agricultural manures common 

 salt is sometimes used instead of nitrate of soda. Both of them 

 look much alike to the eye, and both deliquesce from moisture. 

 But the best way for you to detect the difference would be to 

 throw a handful on the fire. If it is salt it will simply burn 

 with the well-known blue lambent flame — if nitrate of soda, it 

 will burn like gunpowder. 



R. N. M. (Adelaide.) — A full description of how to make 

 and use carmine and picro-carmine staining will_ be found at 

 pp. 35 and 79 of Dr. Marsh's book on "Section-Cutting," 

 published by J. A. Churchill, New Burlington Street, London. 



C. D. — You will find an excellent description of the Anatomy 

 and Physiology of Birds in the collected papers of the late 

 Professor Garrod, also". in''the volume of Cassell's " Natural 

 History" (edited by Professor Duncan), devoted to birds. 

 Roberts' "Popular History of the MoUusca," price los.dd.. 

 published by Lovell Reeve & Co., has excellent plates, but we re- 

 commend Dr. Gwyn Jeffrey's " Marine MoUusca," a really 

 full and complete book, with uncoloured plates of all the 

 leading types. 



K. D. — Make a strong solution of chloride of lime in hot 

 water, and leave the corals in all night. They will take no 

 harm, unless very delicate. Move them to and fro in the 

 water next morning, to wash off the dirt. 



Dk. Cunnvnghame. — The "Popular Science Review" has 

 not been issued since 18S0. 



W. H. Charles. — Accept our thanks for the article.
