The temperature dependence of the photo-electric effect with the image field is discussed, the result obtained agreeing with Fowler's T2 law near the threshold. Fowler's law is discussed, and shown to rest upon a mistake in the normalization of the free wave functions.
The two methods of analysing experimental results due to Fowler and Du Bridge are also discussed, and it is shown that in general the latter should give the more reliable results.
The author wishes to repeat his thanks to Prof. R. H. Fowler and to Mr A. H. Wilson for their constant interest in the work.
