Dykes offers his opinions on what horses are best to cross with, choosing the modern Hackney and an Arab Highland cross. He says he will inform Ewart about the white maned mare which belongs to a carting contractor whose stables are in Portobello.

There is also a copy, in Dykes' hand, of the programme for the Highland and Agricultural Society, Inverness Show, 1839 and a copy of a letter to Dykes on behalf of Lord Lovat about a pony stallion 'Alan Kingsburgh'.

Byrne reports that there is no progress concerning the Connemara ponies and that the 'Department' in Ireland are sending Hackney and Welsh cobs despite the fact that crossing a Hackney with a Connemara pony was a failure. He enquires after the 'new arrangement' between the University of Edinburgh and the Royal (Dick) Veterinary College.

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.
