Tegetmeier thanks Ewart for his article on zebra mule hybrids. He also asks Ewart for a photograph of the hybrid for publication (in The Field newspaper, which Tegetmeier edits) and congratulates Ewart on his 'satisfactory experiment both from a scientific and economic point of view.' Tegetmeier states that he regards the zebra mule as being of great importance as all the other Burchell zebra hybrids he has seen were hinnies or jennets.

Tegetmeier writes concerning mule mares. He also reports some 'gossip' about Dr Butler of the British Museum and his assertion in The Feathered World that he had seen two mules in foal in a drove of 50 in Spain, and the driver had told him mule mares were often infertile. Tegetmeier remarks 'That a man in his position should publish such nonsense is very unsatisfactory'.
