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.

Hally thanks Ewart for sending him his papers and provides some autobiographical details about his own experiences in livestock breeding.
