Communicated by Charles Galton Darwin. Has no modifications to suggest. Criticises how the non-homogeneous character of the demformation has been overlooked, 'but this is an old criticism, and is best considered in a discussion'.

Contains extra question - 'Is there any information contained in the paper which likely to be of value to the enemy?' Referee replies no.
