Sir, - Congratulations to Yvonne Healy on her excellent feature regarding the research of Dr Peter Francis and the origins of Irish lead crystal craft (The Irish Times, July 11th). However, it should be pointed out that much of this work involving both the excavations at Templeogue House and the subsequent research pertaining particularly to this important find was funded by South Dublin County Council, whose support and consideration we gratefully acknowledge. - Yours etc.,
D.L. Swan, Archaeologist, Managing Director, Fitzwilliam Place, Dublin 2.
