Paper read before the Société d’agriculture, histoire 
naturelle et arts utiles de Lyon, on 29 Nov. 1878. The 
author concludes from experiments made upon the 
chrysalids of bombyx cynthia, with electricity and by 
subjecting the chrysa.ids to various degrees of cold, 
that “there is a great analogy between the physiolog- 
ical phenomena of the life of the chrysalids and of that 
of the eggs of bombyx; the sleep and the reawakenin 
of the chrysalids resemble very much the sleep and 
reawakening of the eggs. In this sense one can say that 
the chrysalis is to the butterfly as the egg is to the 
larva.”’ G: D. (25093)

The chorus reads: 
Then let the cockroach giggle in his corner on the floor, 
And the red ant in the closet laugh away; 
While the old daddy-long-legs in the centre parts his 
hair, 
From childhood’s home I never long can stray.
