Forsyth writes that he has sent on the draft 'Sire and Service of Mares' from 1906 to Mackintosh and would be glad of any rough notes on the Monkstadt ponies (the experimental farm of the Congested Districts Board). The back of the letter contains notes in Ewart's hand on a list of names to whom he has sent his 'Tarpan' paper (possibly 'The Tarpan and its Relationship with Wild and Domestic Horses').

Letter is undated but likely to be from the year 1905.
