“ In early life he devoted himself to mathematical and mechanical researches. In 1641 he entered the service of Charles I., who, in 1645, sent him to treat secretly with the Irish Catholics and to raise troops for service in England. The secret was discovered, Worcester was imprisoned on the charge of treason, and Charles I. disowned him. After his release Worcester spent four years in voluntary exile, and upon his return to England in 1652 was imprisoned in the Tower until 1654. ”
