* (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. vo!.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. velutina . Mr. B. adds, “ its splendour is, doubtless, 
enhanced by the surrounding twilight gloom; but it is caused by rays of light concen¬ 
trated 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
