Thursby-Pelham writes that she would happily let Ewart use her drawings for his work on the Antarctic Penguin, but that strictly speaking they are the property of Mrs Assheton, as Thursby-Pelham drew them whilst working as Dr Assheton's assistant. Mrs Assheton has written to Harmer to grant the required permission. She offers Ewart her collection of bird embryos which she acquired for the purpose of comparison with the penguins.

The date is not written on the letter, but is probably contemporaneous with Ewart's work on the moulting of the King Penguin in 1917.
