PHOSPHORESCENCE. 80 
darkness, with the capture of prey or the alluring of their enemies. 
(sic), nor with the illumination of the depths of the sea. This may 
or may not be so, but we are on safe ground when we say that from 
the point of view of the design that is apparent throughout Creation 
there must be an intention of some kind, and were it only to cause 
our admiration it would sufiice. 
Professor Panceri has applied the spectroscope to the examina- 
tion of the light which proceeds from various marine organisms. In 
the case of APPENDICULARIA, in which the colour of the light varies, 
shewing red, blue, and green, the spectroscope shewed the light as a 
continuous band without bright lines. In the case of Puotas, a 
spectrum was formed, ranging from line E in the solar spectrum to a 
little beyond F. Umpexiata shewed a spectrum between Band D. 
Concluding the remarks on marine phosphorescence, it is plain that 
the number and variety of the living things of the sea which can 
produce, or assist in producing, this beautiful phenomenon is very 
considerable indeed. 
The luminous Centipede is worthy of separate mention, an 
insect which has not unfrequently been mistaken for the Glow-worm 
at first sight. Handling soon makes the difference clear. The 
luminous Centipede may reach a length of three inches (Wood). It 
is of a yellow colour, with a rusty-red head. It is sometimes found 
_ coiled within very ripe or over-ripe fruit—peaches, apricots, and 
plums. Its general build is very much that of the ordinary reddish 
| Centipede, but much thinner. The light seems to come from all 
segments of the body, but I am not aware of any special observations 
on this point. 
Luminous Func1.— Where these occur at their best they are 
described as being very beautiful indeed. One has read of a small 
party of explorers finding their way in darkness through difficult 
forest paths in Brazil, the native guide having fastened a luminous 
_ Fungus on to his back,the light apparently being not only sufficient to 
i shew where the guide was, but to illuminate the surroundings as well
