Isinglass b c 1890 (Isonomy - Dead Lock, by Wenlock). Sire Line Sterling. Family 3-m.

Bred and raced by Major Henry McCalmont, he was admired for his gameness and stoutness despite his inherent laziness. It was said that he often left his jockey rather more tired than he at the end of a race. A Triple Crown winner, his only defeat came from Raeburn (b c 1890 St Simon), although an ongoing rivalry with Ravensbury (b c 1890 Isonomy) had made his jockey work.

He was described as a "beautifully made horse of size and substance" with a "splendid shoulder, strong back, lengthy muscular quarters and capital bone" although it was said that his forelegs were inferior to those of his sire.

He went to stud at Cheveley Park, near Newmarket, where he was twice second on the list of Champion Sires although he did not get the best mare books. His most important son was probably Sir John Thursby's John O'Gaunt (b c 1901) who in turn sired Lord Derby's Champion Sire Swynford (br c 1907), the latter getting the Champion Sire Blandford (br c 1919, who in his turn got the Derby winners Bahram (b c 1932) and Blenheim (br c 1927). Blenheim was the sire of the Derby Italiano winner Donatello (ch c 1934) and the Derby winner Mahmoud (gr c 1933). Isinglass died in December of 1911.
