TRANSLATOR’S NOTES. 
Note 1. — The following is a short abstract of Professor Koellilcer’s “ Obser- 
vations on the Nature of the Luminous Organs of the Gloiv-ivorm (Lampjris)” 
(with comments on their bearings in regard to the subject under consideration.) 
which were translated by the writer, and published in extenso in the “ Micro- 
scopical Journal” for 1858, p. 166. 
Lampyris possesses, upon certain rings of its body, a double series of 
flattened luminous plates, appearing white to the naked eye, and presenting 
the greatest amount of luminosity when viewed from above. These organs 
consist of an “ investing membrane,” inclosing a “ parenchyma” (internal 
substance) “ composed of cells, trachea” ( i.e . respiratory tubes), “ and nerves.” 
The cells which constitute the internal substance of these organs are of two 
kinds, called by Kcelliker “ pale ” and “ white ; ” their structure is minutely 
described by him, also the tracheae and nerves, of which he has carefully fol- 
lowed the ramifications. 
We may at once here state, that if Kcelliker’s observations in this respect 
be accurate (and he is a careful and reliable observer), the luminosity camiot 
be the result of combustion, any more than in Noctiluca, for it proceeds in 
the very depths of the vital organism, amongst delicate respiratory tubes, 
“ forming the most abundant and elegant ramifications among the pale cells.” 
“ Now” (the observer continues), “ the proper luminous substance does not con- 
sist in the white cells,” but in the “ pale” ones, “ as may be readily proved by 
direct observation of the luminous organs under the microscope by night, 
when the light of the lamp is shut off.”
