and a half or four turns: lastly, some very long are curled as 
many as eight or ten times. | 
This is how the butterfly makes use of its trunk: When it is | 
fluttering round a flower, it will very soon settle on or quite 
close to it. It then brings it forward entirely or almost en- | 
tirely unrolled; very soon afterwards it almost straightens it, 
directs it downwards and plunges it into the flower. Sometimes 
it draws it out a moment after, curves it, twists it a little, and 
sometimes even curls it partially up. Immediately it straightens 
it again to plunge it a second time into the same flower. It | 
repeats the same mancuvre seven or eight times, and then flies 
on to another.
