NOTES—ORIGINAL AND SELECTED. 131 all males, with one exception. It is probable, if the weather improves, that the butterfly will increase in numbers ; but I fear we cannot now anticipate a repetition of the prodigious flights of 1887. Cynthia cardui (summer brood) has appeared in very great numbers, frequenting the Black Knap-weed fringing the cornfields and lanes near the sea ; patches of this plant with dozens of this insect, and "Red Admirals," "Blue," "Copper," "Wall," and "White" butterflies settled on and flitting about the blossoms in the sunshine, sometimes presented a marvellous spectacle of ever-changing colour.—W. Cole, East Mersea, August 15th, 1892. Monotropa hypopitys (Yellow Birds-nest) in Epping Forest.—On examining a bundle of letters from the late Mr. James L. English, I find that on July 26th, 1887, he sent me specimens of Monotropa from Epping Forest, which he had just gathered, probably from some spot in the forest near Epping. The observation is worth recording, as the plant is rare in Essex, only two stations being given by Gibson : namely, Audley End and Danbury.—W. Cole, Buck- hurst Hill. Damasonium stellatum in Epping Forest.—Mr. Britten writes as follows in the "Journal of Botany," for August, and although it is true that the specimen found by Mr. Powell had been wilfully introduced (see ante, p. 117), Mr. Britten's remarks are interesting and suggestive :—"It is unfortunately only too certain that this pernicious practice of plant-introduction has been carried on lately, but I think it at least possible that the case of Damasonium may be one of survival. When living at High Wycombe, in 1867, I found the plant, in no large quantity, in one pond on Naphill Common. It decreased in abund- ance during the next year or two, and I searched for it in vain in the neighbour- ing ponds. On revisiting the place in 1890, I found it in its old habitat, and also, in much greater abundance, in a pond and marshy ground at some little distance. This year the plant is exceptionally luxuriant in this latter pond, the specimens floating in the water at some distance from the margin being the largest I have ever seen. There is no reason to suspect an introduction in this case ; and it would be interesting to know whether Damasonium is one of the plants which disappear for a time and then re-appear. It was formerly frequent in the Wanstead and Epping Forest districts (see 'Flora of Essex,' p. 326), and Mr. Powell says it was 'found in Wanstead Park soon after it was thrown open to the public' The 'English Botany' figure (t. 1615) is from a Wanstead specimen, and Sowerby gathered the plant 'frequently in Wanstead Park' ; and Edward Forster notes on his specimens in Herb. Mus. Brit., 'In ponds and gravel-pits on the forest between Walthamstow and Wanstead.' I am inclined to doubt whether Mr. Powell is right in classing Damasonium as now existent in the forest area as an alien, but the lamentable action lately taken renders it impossible to come to any satisfactory conclusion." Local Scientific Societies' Committee of the British Association.— We understand that successful meetings of this Committee took place during the Edinburgh Congress of the Association. Prof. Meldola, who has usually acted as Delegate of the Essex Field Club, was Chairman of the Committee, and Mr. T. V. Holmes (who is now Secretary) represented the Club. The subject of Local Museums was brought forward, and will probably form a leading item in the Agenda for the next year's meeting.
