Referee's report by Charles Galton Darwin, on a paper 'The electrical properties of the muscle fibre membrane' by Bernard Katz Sectional Committee: Physiology and Medical Sciences Recommended for publication in the 'Proceedings of the Royal Society of London'. Can only give a general impression as much of the matter is beyond his understanding. The work is good but leisurely in style. Suggests not all of the experimental precautions need to be outlined in such detail. Suggests someone other than the author go through the work with the aim of reducing its length.
