Letter to James Cossar Ewart from J.B Robertson, 15 January 1916

 Item
Identifier: Coll-14/9/22/12
Scope and Contents Robertson comments on Ewart's paper on the development of the horse, particularly on the 'three-toed phase' in early embryonic life. He wonders whether there is any appreciable difference between the embryo of an Arab or thoroughbred mare and a Shire. He imagines that the three-toed stage would persist for two or three days or longer in the case of heavy, coarse breeds.

Letter to James Cossar Ewart from J.B Robertson, 18 November 1910

 Item
Identifier: Coll-14/9/16/35
Scope and Contents Robertson writes that he had come to the same conclusion as Ewart that a slender horse played an important part in the ancestry of the English thoroughbred. He has compared various fossilised remains and concluded that although the shaft of the central portion of the large metacarpal bone is broad, the shapes of the first three phalanger are indicative of a slender race. He makes several observations on the significance of the metacarpals.

Letter to James Cossar Ewart from J.B Robertson, 26 November 1910

 Item
Identifier: Coll-14/9/16/42
Scope and Contents Robertson writes that he is enclosing a reply to Professor Wilson which he has sent to be printed in Nature (reply not present). He does not see why Wilson considers himself superior in questions relating to the pigmentary character of the Equidae, as Robertson has noticed many errors in Wilson's own work in his paper on coat colour now before the Royal Dublin Society.
