Thick, multisequence deposits of ice-contact sediments in the deep floors of Eastern and Western basins and on the seaward side of the sill at the entrance to Hudson Strait attest to the magnitude of glacial ice streams in Hudson Strait. Some of these are thought to have extended to the shelf edge and to be a source of Heinrich events in the Labrador Sea and North Atlantic Ocean. Later south-to-north ice advances across Eastern basin onto southeastern Baffin Island were less far-reaching seaward. The sediment record in the floor of Eastern basin and on its northern and northwestern flanks show that the basin was occupied by a grounded and progressively thinning ice sheet during the time of the Noble Inlet advance recognized on southeastern Baffin Island. Chronological data and similarities in the marine-terrestrial ice-sheet behaviour patterns suggest that this was one and the same ice sheet. Three potential sources for this advance are examined: Baffin Island, a Hudson Strait ice stream, and Quebec

During archaeological excavation of St George's church, Canterbury, 269 skeletons ranging from early medieval to late nineteenth century were recovered. A medieval female aged ca. 23-28 years displayed an unusual dental anomaly, an odontome. Odontomes are infrequent in clinical dentistry. A search of the literature suggests thzt very few archaeological examples have been published and our specimen is the first excavated case reported from Britain. Archaeological material, if subject to radiographic examination, provides a unique source of information for the prevalence of odontomes from prehistoric to modern times.
