 it seems to me, inevitably happen. Anyhow, it is freely open to 

 discussion, and I claim to do no more than briefly outline the prin- 

 ciples which, I consider, must govern a subject on which there has 

 been so far singularly little opinion expressed.

 when scientific discussion was felt to be a necessity owing to the 

 conditions of overtime, night work, Sunday work, and women's employ,
