He States that in his first paper he 
showed that ty immersion in spiri tuous li- 
qucrs, various cils, irrespirahle gases, 
acid vapors, tchacco juice, camfor, sclutions 
of cpium, etc* , thè iight of thè lucida 
is not extinp'uisht even after deth. He 
then takes up thè results of new experi- 
m.ents with various gases: 
Sulfur Dioxid: The live insect rr.cved and 
s cintillated 5 hut soon died, or appeard tc 
die; Vv'hen allowd to remain, however, it con- 
tinued to giv forth a uniformi light, The 
luininous mattcr of thè insect prest out on 
a vv'hite card left a lumincus ebrea h, which 
when introduced intc thè sanie gas was net 
affected, hut scon died out. 
Carhen Dicxid: Bcth thè live insect and 
thè luminous matter ccntinued to shine as in 
air. 
Litrous Anhydrid: For ahcut ten minutes 
thè insect preserva thè sanie appearance as 
in air, and gave light; it was removed freni

of thè influence of thè atn.csphere , did not

m.aterial of an insect ccntinued tc glow for 
two hours in thè gas. After heing exting-

Airmonia: After a few moments thè insect

they wer extinguisht. 
Hitrogen: The live insect ccntinued to
