Palk Welland among the dark, cavernous rocks of Dartmoor. E.)*

(Since writing the above, we perceive a like phenomenon has been observed by Mr. J. E. Bowman in the shady recesses of Rowter rocks, a mile or two north of Winster, Derbyshire; as reported in Mag. Nat. Hist. vol. ii. p. 407, fig. 106. Mr. B. attributes this "golden green light, perfectly phosphorescent, seen to the greatest advantage at the distance of a few yards, and losing its resplendent character when brought into the full light," to some minute vegetable furnished with a peculiar organisation. Nothing was visible upon the surface of the stone but a filmy irregular network of green, scarcely perceptible from its delicacy of texture, when highly magnified having the habit of a Conferva, and approaching nearly to C. veluting. Mr. B. adds," its splendour is, doubtless, enhanced by the surrounding twilight gloom; but it is caused by rays of light concentrated by, and reflected from, the innumerable and inconceivably minute lenses of the leaf.” It is denied that this light can be emitted either from the more obvious interspersed Musci, or reflected from the silicious particles of the gritstone. Were it not presumptuous to

venture a conjecture without having seen the identical specimens, we should be disposed to consider this questionable production might prove to be var. Conferva gelatinosa, or some analogous species. Consider also Note, vol. iv. p. 70. E.)
