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 3in in height, while the large 
one lifted its expanded umbel to the altitude of at least 9in.,—a giant by the side of a pygmy. 
Both flowered at the same time; both within Gin, 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 curidsity, 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 following spring not 
a trace of it remained. Tam, &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 faxifolium), 
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., 1s 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 separating 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 fossils. —Y. December, 1829. 
Conia pordsa. — Sir, It has been asserted that no fossil species of Conia 
have been found. I had, however, the pleasure of gathering, last year, 
from the crag pit in Tattingstone Park, Suffolk, a very perfect specimen of 
“ Conia pordsa” attached to an ancient fragment of a Pécten. 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, Hchinus, 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 
ae yours, &e.— W. B. Clarke, East Bergholt, Suffolk, September 3.
