HARDWICKE'S SCIENCE-GOSSIP. 



Wilson Noble. — A capital plan to obtain the skeletons of 

 small mammals is to skin the bodies and place them in ponds 

 where tadpoles arc abundant. The latter eat away the flesh 

 without disturbing the bones, only the process must be well 

 watched. Vou will find Tulk & Henfrey's "Anatomical Ma- 

 nipulation " (published by Van Voorst) a capital handbook and 

 guide. See Dr. Giinther's " Introduction to the Study of 

 Fishes" for instructions as to preparing them. Chapters in 

 "Notes on Collecting and Preserving Natural History Objects " 

 (published by D. tJogue, price 3.?. 6^/.) relate to osteulogical 

 preparations, the preparation of land and freshwater shells for 

 the cabinet, &c. 



J. A. Ollakd. — The "remarkable tree" of which you speak, 

 which is said to have the power of drawing up bones, &c., is 

 one of the nuisances of a journal like ours, and is always crop- 

 ping up. The story is on a par with that of the " upas-tree " of 

 Java, which has gradually been heard less of as we have known 

 more of Java. The " remarkable " natural objects observed by 

 missionaries always require to be accepted with caution. 



W. J. W. S.— The "small blister-like pieces" on your fern 

 leaf are^not fungus, but " scale-insects," or the female of Coccus 

 squantifcr, whose body becomes a cocoon-like shelter for the 

 eggs she lays. The fern appears to be a tropical Pteris, but the 

 fragment is too small to identify. 



A. Jenkins. — The sketches (which are very vigorous and 

 accurate) are those of a stalked Infusorian, evidently Epistylis 

 anastaiica, 



R. A. Dempsev. — Wc do not recommend you to try a solution 

 of chlorate of potash for your flowers. There is nothing like 

 complete drying and frequent changing of paper. Vou will not 

 be able to do this effectively without a press— it is impossible to 

 get rid of the moisture otherwise than by using one. See two 

 capital articles in Science-Gossii' for 1S78 by Mr. J. W. 

 Buck, B.Sc, on " How to Make a Herbarium."
