Nucleation' by T E Faber Sectional committee: Physics Paper reference code: A59 Recommended for publication in the Proceedings. Mott writes: 'As far as I can judge, this is a good and careful piece of work and well written. I do not claim, however, to be in any way an expert in this branch of experimental physics, and feel that the paper should go also to someone like Professor Simon or Professor Allen who is.'
