Mean length = 0*9925 inch. 



Longest fibre = 0*2075 inch longer than mean. 



Shortest fibre = 01 925 inch shorter than mean. 



The lengths here are more regular and within a narrower 

 compass than in the preceding sample, while the mean 

 length is but slightly different ; it is therefore more even 

 and regular in length of staple.

Mean length = 0*970 inch. 



Longest fibre = o*i8o inch longer than mean. 



Shortest fibre = 0*120 inch shorter than mean. 



Though these hairs show a less mean than the preceding 

 two samples, they lie well together, 80 per cent, being 

 within Q- 1 inch of the mean, and the extreme difference 

 being 0*3 inch.
