and " habitual " was emphasised, and means were described 

 by which the more efficient methods may increase interest 

 in life both directly through their own nature and indirectly 

 through the increased leisure, husbanding of energy and 

 higher wages which they make possible. 



In the discussion which followed, Dr. William Cramp, 

 M.I.E.E., pointed out the dehumanising tendencies of ex- 

 periments designed to achieve maximum output, and 

 questioned the desirability of extreme specialisation from the 

 point of view of the development of the individual. He 

 suggested also that it was better to encourage individuals by 

 lectures such as those of Professor Pear to take a pride in 

 finding their own most efficient methods than to attempt to 

 force upon them methods similarly deduced by the manage- 

 ment.

 found by division sums. Let A" be the number whose «th root 

 is to be found, let G be a convenient number near to the 

 probable value of A, then the approximate root is 



(* + i) A" + (n-i)G* 

 K ~ u (« + i)G" + (n-i) A"
