LETTER-BOX. — ^What is a Diatom 1 — In answer to several letters on this subject, the Editor refers to Mr. Tuffen West's 

 continuation of the subject in the present Number. The organization of Diatoms will be treated next month, and subsequently other 

 divisions of Infusoria will receive attention. — Silting — The queries of the C — class are answered in Mr. Mackie's paper, " The Ceaseless 

 Work of the Sea." — Zeta — Thanks for your very practical suggestion. — Expkeimkntal Philosophy — L.M.B.; Curriculum; and 



Members of the J CoUeee — A series of papers are in preparation. The subject proposed by Mr. Lawson has been amply treated in 



standard works, and it would profit nothing for us to \io over a subject to which nothing can be added. — Postable Chess Board — We 

 have received from Mr. Beale, 4, Grove Terrace, West Ham, Essex, a paper Chess and Draught-Board, with set of men in a box, which 

 Mr. Beale sends to purchasers for seven stamps. Young people will find it useful to carry with them on excursions, and it is also well 

 adapted for work-people to use during meal-times.^ — Flints in the Deipt — E. T., Bridlington. The subject is one of great interest, and 

 we must all guard against coming to conclusions hastily. — Lkech Aquakium — N. We advise you not to add any fishes or other animals, 

 and to use Anacharis alsinastriim as the only form of vegetation, except such confervoids as occur spontaneously, and of these destroy as 

 little as possible. A portion of the glass may be kept clean by means of a sponge attached to a stick, and otherwise the conferva should 

 be allowed to grow in its own way. — Correspondents not answered here may rest assured that their letters are under consideration, and 

 that there are proper reasons for not immediately replying to them. — Goruam's Colour-Top in type, and will appear next month.
