Mean length =1-252 inch. 



Longest fibre =0*29 8 inch longer than mean. 



Shortest fibre =0-302 inch shorter than mean. 



In this cotton, which stands next to Sea Island for 

 mean length, we find a difiference in the mean of o* 192 inch, 

 while in the longest hairs of each we have a difference of 

 0"5 inch, and in the shortest a difference of 0*15. It is 

 a tolerable even cotton, the extremes not being very far 

 apart, and but few hairs presenting extreme measurements, 

 not less than one-half of the whole number of hairs being 

 within O'l inch of the mean. The next two samples of 

 cotton approach very near to this, the Maranham being 

 within 0*032 inch of the mean length, and the second sam- 

 ple of Egyptian within 0*035 inch of the Maranham. This 

 sample of Maranham has no hairs so long as the longest 

 hairs of the Egyptian ; but it has many hairs of 1*4 and 1*3, 

 which bring up the average to nearly the same, while its 

 shortest hairs are the same as the Egyptian ; it may be 

 considered very even, so great a number of hairs being 

 close together. The second sample of Egyptian falls 0*067 

 inch below the first, owing to a want of long hairs ; it is 

 much less even than the Maranham, the extremes being 

 0*65 apart, while in the Maranham they are only 0*45 

 apart.
