when the flower was cut, with a view to dry and preserve it. It was so preserved, and in drying 

 two of the flowers were detached ; the whole have acquired a greenish tint, except near the 

 mouth, where the natural tint of orange is tolerably well retained. Close by the side of this 

 enormous cowslip grew a little one, which I had recently brought from the summit of a chalk 

 down. This cowslip flowered also : it might possibly be from 2 to 3 in in height, while the large 

 one lifted its expanded umbel to the altitude of at least 9 in., — a giant by the side of a pygmy. 

 Both flowered at the same time; both within 6 in. of each other; the one produced fifty-three 

 large flowers, the other three of only a moderate size. As this communication has no other ob- 

 ject than the introduction of a curiosity, I shall bring it to a close, by remarking that the large 

 plant died after performing this feat ; it perished in its greatness, and in the follov/ing spring not 

 a trace of it remained. I am, &c. — Electricus. Grove House, April 24. 1829. 



A singularly brilliant golden green Light. — When making a tour in Corn- 

 wall in the year 1815 I was struck by a " singularly brilliant golden green 

 light," similar to that described in your Magazine (Vol. II. p. 406.) On 

 looking into a small cavern by the roadside, near Penryn, I observed in its 

 recesses a small moss (apparently minute plants of Dicranum ^axifolium), 

 which, when seen in some particular positions, appeared of a most beautiful 

 emerald-green colour with a phosphorescent brilliancy. In De Luc's 

 Geological Travels^ vol. iii. p. 131., is the following account of a similar 

 phenomenon : " Passing by Botter Rock, Mr. Hill led me to a part of the 

 foot of that Tor, where there are hollows like small caverns ; and in these 

 he showed me a vegetable phenomenon, which I had never seen but in the 

 granitic mountains sepai'ating the country of Bayreuth from Bohemia. The 

 innermost part of these cavities is lined with a very pretty moss, which 

 reflects the light in the same manner as the eyes of a cat. So little light 

 reaches these remote recesses, that, on looking in from without, they appear 

 quite dark ; but, when viewed from a particular point, the part of the rock 

 which is covered with this moss is suddenly seen to shine with a fine emerald- 

 green." — W. C. T. September, 1829.

A Star-stone on Flint. — I send the enclosed full- 

 size sketch {fig. 34.) of an impression of a star-stone 

 on flint, not because I think it rare, but in hopes that 

 some of your correspondents may be able to say 

 whether star-stones in general have or have not been 

 thus radiated, and thereby throw some light on the 

 origin of these elegant fossUs. — F. December ^ 1829. 

 Conia porosa. — Sir, It has been asserted that no fossil species of Coniae 

 have been found. I had, however, the pleasure of gathering, last year, 

 from the crag pit in Tattingstone Park, Suflblk, a very perfect specimen of 

 " Conia porosa " attached to an ancient fragment of a Pecten. I beg to 

 add, that a gentleman who was studying the crag formation at Waltham, in 

 Essex, showed me, about a month since, a very beautiful, though extremely 

 minute, Echinus, with one of its spines uninjured, which was taken from 

 the Naze Cliff. 



I believe these are new discoveries ; at any rate they are an addition to 

 the list of unpublished crag fossils given by S. V. W. in your Magazine 

 (Vol. II. p. 246.), although some of the shells in that list had been pre- 

 viously published, and by Mr. Taylor himself, in the Magazine of Natural 

 History (see Vol. II. p. 26.), as may be seen on comparing the lists. I 

 am. Sir, yours, &c. — W. B. Clmhe. East Bergholt, Suffolk, September 3.
