348 OB SEX VA TIONS ON INSECTS. 



I saw a prodigious swarm of these ants flying about the 

 top of some tall elm-trees (close by my house) ; some were 

 continually dropping to the ground, as if from the trees, 

 and others rising up from the ground \ many of them were 

 joined together in copulation ; and I imagine their life is

By observing two glow-worms which were brought from

 these little creatures put out their lamps between eleven 

 and twelve, and shine no more for the rest of the night. 



Little glow-worms, attracted by the light of the candles,

 but come forth when there is no frost ; they travel about in 

 rainy nights, as appears from their sinuous tracks on the 

 soft muddy soil, perhaps in search of food. 



When earth-worms lie out a-nights on the turf, though 

 they extend their bodies a great way, they do not leave
