ConvocatION OF SPARROWS.- Passing up St. Dunstan's Hill to-day, at 4 P.M., I descried a flock of sparrows on two trees, about 500 or 600 in number. Tliey made a great noise for about ten minutes, and then all flew off, creating quite a sensation among the people. Is such a thing rery, cenimon (especially at this season of the year)? And why do they all flock, and then fly off if it is not common?-J..1.,ju. Dec. 12, 1565.

GOOD CEMENT.-H. J. B. asks if any one can recommend a good cement for aquaria ?
FIBRE OF THE COTTON PLANT.-Would it not be possible to extract the fibre of the stem of the cottou plaut (Gossypium herbaceum, &c.)? I believe this is worth an investigation, and I recommend it to all who are acquainted wiihi cotton growers. I tried a small delicate stem, put here in open ground, and got some fibres by beating it. -- Bernardin, Vclle, near Ghent.

VISITATION OF SPIDERS.-It may interest your northern correspondent and others to learn that the spiders alluded to at page 282 of your December number have visited the south. On returning from chapel after the morning service on the 12th Novemher last, I observed the railings from St. Thomas's Street to one of the entrances to Victoria Park swarming with almost any quantity of them; but, strange to say, I could not find a single specimen on the leafless twigs of the trees in the park, and tlie railings beneaili them had only here and there one. They were very tame, running, about the hand freely, and leaving it by attaching a thread to its margin, and so dropping down five or six inches, pausing thus for a moment, and then, with almost the speed of a winged insect, mounting high in the air, where their intensely black bodies could be seen in the bright sunlight some yards away. Accepting the belief that the aerial spiders make their flights by the lightness of the silk they throw off, it would be interesting to learn-first, how our little visitors contrived to detach the thread from the hand, or whether they merely held on by it while they spun another thread that was free? Secondly, why the thread from the same creature at one time is a mere rope of suspension, and at another acts the part of a balloon ? "Is it possible that the spiders capable of making these atmospheric ascents have some mcans, liitherto unknowil, of inflating the air sacks
or other part so as to reduce their specific gravity ? I spent some time the following morning in examining the railings, ground, and crevices in the locality where the previous day they had been so plentiful, and yet with the help of ten years' experience in such hunting I could not find a single individual. Their threads were there, stretching from point to point like fairy telegraph wires, that mighit have been put up hy some joint stock enterprise from the realms of Queen Mab; hut of the workmen I saw none, alive or dead. Their task completed here, on what other fields has their great Maker employed them ? -W. H. llall.
ATDIOSPIIERIC PHENOMENON--While trarelling from Oxford, on the London and North-Western Railway, on the 20th July, I witnessed what, to me at least, was a novel phenomenon. The sun was 4 or 5 degrees above the horizon, the time being 7.40 P.M. In the cast a dull haze extended some 9 or 7 degrees above the horizon, and terminated in light flocky clouds; above these the sky was clear. Exactly opposite the place of the sun a beam of light shot up from the horizon, extending across the haze and clouds as far as the clear sky above. In the course of about a minute three or four more beams became visible, apparently radiating from a point, situated as far below the castern horizon as the sun was at the time above the western. The most southerly of the beams appeared faintly tinged with prismatic colours. I turned towards the west, thinking the sight I had witnessed must be il reflection of the “Moses' Horns," so often seen when the sun is on the point of setting, but could not see anything of the kind. The appearance lasted, with varying intensity, for about ten minutes, fading away gradually, and quite disappearing before the sun had set. After the sun was below the horizon, a broad streak of rosy light filled the space before occupied by the beams, as though Aurora, having mistaken the hour, was about again to open the gates of day before Apollo had had time to repos.-W.S., Buckingham.
THE SPAWN Or Doris.-Would the spawn of the Doris (Doris phleta), deposited in my tank, ever hatch? If so, would the young ones grow in an aquarium? The Doris spawned on the 1st of November, Could any of your correspondents answer the above questions?-1V. B.
PRESERVING Birds WITII Wood Acid.- Ir. Newton, of Cambridge, says in his
Hints on making Collections of Eggs”: “Birds may be preserved entire by pouring a few drops of pyroligneons acid down their throats.” I presune this would only keep them for a time, until they can conveniently be skinned. Or would it entirely preserve them without any other process? Perhaps some of your correspondents have tried the plan, and could speak as to its results.-W. F. Saunders.
Cuixa Griss.-I believe different nettles are known under that name. According to Dr. Blumc, the name of tchoum is given by the Chinese to Bæhmeria spicata, Thunb.; and to B. longisprica, Steud. ; the RHEA of Assam is B. nivea and B. tenacissimai, Gaudich.; the TANEN, RAMI, &C., of the Malay is B. tenacissima. Dr. Blume says (in Mus. Ludg. Bat.) that B. tenacissima is produced by cultivation m B. nirea.-B.
