Scope and Contents

Martin advises Ewart that his notion of keeping a farm at Crosswoodburn is impractical for financial reasons. He says he is glad that 'the two hybrids' have gone to Mountain Batteries as he hopes it may lead to them being bred in India. He also mentions that Ewart 'should get a big price for 'Romulus' (Ewart's first zebra hybrid) now as he is a hybrid with a past'. He encourages Ewart to publicise his findings from his hare-rabbit cross-breeding.

Scope and Contents

Hally provides information gathered from his own experience of breeding experiments, chiefly concerning the persistence of the belief in telegony among breeders and the inheritance of colour in Dachshunds, Hackney stallions, rabbits and mice. He states that he believes that mental ability is inherited from the dam but temper from the sire, something which is not reflected in the higher consideration afforded to sires.

The second page of the letter is not present.

Tegetmeier states that he will look out in The Field for any references to hare-rabbit hybrids, which he suspects are impossible. He also says he will place an advert in The Field for a white pheasant cock for Ewart and make enquiries about Dalmatian pups.

Evans writes that he is passing over to Eagle Clarke's part of the Annandale series of papers to the Royal Physical Society, and recommends that the paper be permitted as it stands. He provides some citations and references to articles which he thinks might be of interest to Ewart relating to the breeding of mice, guinea-pigs, rabbits and fowls.
