The Revd Professor Christopher C. H. Cook, the Co-investigator on the Hearing the Voice Project at Durham University, funded by the Wellcome Trust, would be grateful for any readers who have had experiences of spiritually significant voices to complete an online survey. The project’s aim is to develop a better understanding of all experiences of hearing voices, God, angels, saints, demons, or other spiritual beings, or of sounds. Anyone over the age of 16 who has first-hand experience of hearing such a voice can complete the survey at https://durham.onlinesurveys.ac.uk/spiritvoices. For more details, contact Professor Cook at c.c.h.cook@durham.ac.uk.

The church pictured in last week’s issue (Gazette, 29 June) has been identified as St Just-in-Roseland, in Truro diocese.
