130 PHOSPHORESCENCE OF EARTHWORM. 
concerning the earthworm appears to have been 
observed by M. Vallot, of the Academy of Dijon, 
as early as 1828. I may add here, that I distinctly 
remember witnessing, when quite a child, the 
phosphorescence of the earthworm; the hght 
appeared connected with the slimy matter that 
covers the animal’s body. It was whilst digging 
at night, in a large dunghill, for worms to supply 
baits for a fishing excursion that my schoolfellows 
and myself turned up many hundred Lumbrics in 
a highly luminous condition ; but I cannot recol- 
lect in what month this happened.
