title: A reply to M. Henry's comments on Cowgill's article (Population Studies, July 1967).
abstract: Abstract   To settle the excellent question that M. Henry has raised will undoubtedly require more research. At present the 17th-eentury York situation is being investigated. The number of matched births and deaths will be considerably greater than that obtained from a study ofthe 16th-century records.
