Ridgeway thanks Ewart for allowing him to reference Ewart's information concerning the Ward's zebra in his forthcoming work, but states he will be careful not to give away too much information about Ewart's own work before he has published his findings. He reminisces about the introduction of Clydesdale stallions to his native Kildare, and the inferior offspring which cross-breeding with the local mares produced. He encourages Ewart not to lose heart in the face of criticism over 'the callosities controversy'.
