ORGANS OF HEARING. 189 
mild and serene, my success was greater and more 
delightful. As all my observations agreed in this 
one circumstance, I omit to enumerate them; for 
the antenne being erect as soon as they were 
put on the alert, they were moyed hither and 
thither by means of loud sounds, for they disregard- 
ed such as were very small. These they may be 
said to have drunk in; and if alarmed by new 
sounds, they rejoiced when they could effect their 
escape as soon as possible, and preserve life and 
safety by the most rapid flight. So I have observed 
very frequently when the antennee were folded up 
in the Lepturee, Elateres, Curculiones, Papiliones, 
Apes ; nay, even the house-fly, as soon as they 
were moved and excited by irregular sounds or 
noise, would erect their antenne, and betake them- 
selves to flight, without any other excitement. The 
Sphinges again, and Phalenc, during the night, 
fly about the flowers of the marragon and other lily 
plants, emitting an agreeable smell; during the 
night, scarcely could a voice be raised then they 
would turn round very swiftly, and the antennee 
appear to be, as it were, convulsed. 
* T must not pass over in silence, however, that 
no evidence more clear could be desired of the sen- 
sibility of the antenn to quick sounds, than what 
occurred to me last summer in my garden, I ob- 
served, in a morning walk, undertaken for the pur- 
pose of catching insects on the hazels, that, while
