Ridgeway congratulates Ewart on the announcement of his marriage. He reports that he has finally got a photograph of the Somali wild ass in Regent's Park from Dando. He mentions forthcoming papers about quaggas from Pocock and Lydekker and concludes by enquiring whether the quagga's markings and its bay colour are to be attributed to its living under the same climactic conditions as the Libyan horse.

Ridgeway provides some details about historical accounts of the first horses brought into Mexico and Texas by the Spaniards, in preparation for Ewart's visit to Mexico. He also passes on information from a local farmer, John Thornton, about bronchos in Mexico, and Hans Gadow about dun and roan horses. He congratulates Ewart on his forthcoming marriage.

The latter part of the letter is not present. The letter also bears the incorrect date of 1905.
