HARDWICKE'S SCIENCE-GOSSIP. 



H. Haines.— Your shells are all correctly named, and many 

 of them are most excellent examples of their kind. 



G. A. Holt.— The object on Briza media was not a fungus, 

 but looks like one of the pollen masses of an orchid, transferred 

 by some insect. 



J. Tempeke. — The micro-fungus on leaf of Lavatera 

 sylvestris is Puccinia malvacearunt, Corda. 



F. C. Kelland. — Your micro-fungus is Phragmidium 

 mucronntum, Fr., see Dr. Cook's " Rust, Smut, Mildew, and 



Mould." , 



Geo Clinch.— The fragment of fossil wood sent appears to 

 be from the Portland beds, but it is impossible to tell from such 

 a small piece. The fossil from the chalk is not a tooth, but 

 part of an encrinite. 



T. W. B.— The drawings sent us for identification are :— 

 No I. Pleurosigma ; 2. Stephanodiscus ; 3. Amphora avails; 

 4. is not a diatom ; 5. Globigerina is an interloper. It certainly 

 did not live with the diatoms, which are all fresh-water forms. 



J. Cunnack.— Masters's " Vegetable Teratology ' was pub- 

 lished by the Rav Society. 



A. B. C.—Marchantia should be pronounced Markantia.
