[2] Galantine was the last recorded foal of Snowdrop, a daughter of Daisy who was a half sister of the St Leger winner Ambrosio.
One of the most important events for juveniles was the Clearwell Stakes at the Newmarket Second October meeting, in which Galantine (officially Sir M. Wood's b. f. by Reveller, out of Snowdrop) made her first racecourse appearance.
Galantine, ridden by Patrick Conolly, had been among the leaders from the start, and held on to win by a neck[7] from Mr Scott Stonehewer's filly Lioness, with Oxygen unplaced.
Two weeks later she earned £100 for her owner without having to compete when her opponent, a colt owned by Lord Jersey, was withdrawn from a scheduled match race.
Four days later she won a £100 match against Lord Chesterfield's Titania over the Ditch Mile and then finished unplaced in a five furlong handicap race later the same afternoon.
[14] On 2 November Galantine won another match, this time beating Lord Orford's colt The Grand Duke over the Rowley Mile for a prize of £100.
[15] On the final day of the Newmarket season, Galantine collected a further £100 when Thomas Thornhill's colt Earwig was withdrawn from a match race over the four mile Beacon Course.
