tenaciously to the calendar of St. Patrick, carried it everywhere in
their missionary labours, so that the controversy was not confined to
Ireland and England. It was long and bitter, until at last the Irish
Church agreed to follow the reform. (See Healy, _Ireland's Schools and
Scholars_, p. 592; Moran, _Irish Saints in Great Britain_, "The
Conference at Whitby in 664," pp. 255-261).

Calendar study is interesting, and many valuable contributions on this
matter have been given to us by Father Thurston, S.J., and other English
and Irish scholars.
