 cottony down attached to the seeds, which makes it un- 

 pleasant to approach them on a windy day, the down being 

 so fine as to penetrate the mouth and nostrils, being borne 

 along in clouds. 



C — Are not these large Sun-flowers some that have de- 

 generated from gardens ? 



F. — No : much as they resemble them, they do not even

 within the main bow was another adjoining it, the prismatic 

 colours recurring in their proper order, and not reversed ; 

 the violet was succeeded by red, orange, yellow, &c. till it 

 ended in violet ; in fact, making one broad bow, containing 

 two sets of colours. The inner set was fainter, but quite
