GREAT LAK THORN- FLY. 
' ** The Indians," says this ladv, once 
brought me, before I knew that tliey shone by- 
Right, a number of these Lanthorn - FHes, 
which I shut up in a large wooden box. In 
the night, they made such a noise, that I 
awoke in a fright, and ordered a Hght to be 
brought ; not being able to guess from whence 
the noise proceeded. As soon as we found 
that it came from the box, we opened it ; but 
were m^uch more alarmed, and insrantlv let it 
fall to the ground, with aiFright, on perceiving 
flames of fire issue out of it : for, as manv 
animals as came out, so manv flames of fire 
appeared. When we found this to be the 
case, we recovered from our terror, and again 
colle61:ed t.he insetfls, much admiring their 
splendid appearance." 
Madame Merian adds, that the light which 
one of these inse£ls afl:ords, is sufficient for anv 
person to read by. 
The phosphoric light dispensed by this won- 
derful insc£l, proceeds wholly from the hollow 
part, or lanilTorn, of the hca<l, no other part 
being in the smallest degree luminous.
