Scope and Contents The material consists of a mix of figures and plates mounted on card, printed copies of figures and loose photographic material, chiefly depicting developing embryos. Contains some figures for 'Teratogenic effects of trypan blue on amphibian embryos' and 'Effects of some amino-acid and purine antagonists on chick embryos', (published in the Journal of Embryology and Experimental Morphology in 1956 and 1958 respectively), and possibly others in addition....

Dendy writes that he has found two embryo specimens which he is sending to Ewart, and he can also send him pieces of adult skin preserved in spirit if he wishes.

Scope and Contents 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...

MacBride thanks Ewart for his telegram with the details he needed about Darbishire for his obituary, which he has sent to Nature. He is delighted with Ewart's work on the embryology of the horse, and believes that 'it is only by slow painstaking work of this kind that a real science of Comparative Embryology will ever be built up.' He is glad that Ewart gives no countenance to the 'crook theories' about the layers of the embryo.

The letter is undated.

Scope and Contents Morse writes that the report containing Ewart's lectures will be ready shortly, and he wishes to know how many separates of Ewart's article he would like to have for distribution. He will be unable to do anything concerning the distribution of breeds in India so he hopes Ewart will, and also that Ewart will make a large collection of skulls from India in adult and embryonic forms. Ewart would also need someone in India to measure all the breeds, and to have a uniform system of measuring. He...

Berry writes concerning the embryo, which he considers the worst of all 'hideous beasts' and makes a differentiation between independent life forms and dependent ones.

The year is not written on the letter.

Hill apologises for the long delay in replying to Ewart's letter. He states that he has no knowledge concerning the appearance of scale papillae, but will hunt for any hybrid embryos he has preserved in spirit and send them on.

Scope and Contents

Robertson comments on Ewart's paper on the development of the horse, particularly on the 'three-toed phase' in early embryonic life. He wonders whether there is any appreciable difference between the embryo of an Arab or thoroughbred mare and a Shire. He imagines that the three-toed stage would persist for two or three days or longer in the case of heavy, coarse breeds.
