OBSERVATIONS UPON COTTON. 



407 



The next three samples are of East Indian cotton, 

 and present a sensibly less mean length than the North 

 American cotton, but not to a greater extent than exists 

 amongst the American cottons themselves ; and the means 

 are only brought down by there being fewer of the longer 

 hairs^ which_, however, are not quite so long as in the 

 American cottons; the short hairs are few, and only a 

 little shorter than the short ones in American.

 Mosley, Esq., labelled ^^Fair Dhallerah, of very good

Mean length = 0*9425 inch. 



Longest fibre = 0*2075 inch longer than mean. 



Shortest fibre = 0*1925 inch shorter than mean. 



The lengths of these hairs are very close about the mean ; 

 it may be said that 80 per cent, are within o* i of the mean, 

 by counting the two lengths 1*05 as being within.
