The image of the parish register is on FindMyPast:
Sarah Isabella Levett, born 8th April 1819, daughter of Matthew & Ann Levett, was baptised on 29th June 1837. Matthew's occupation is 'chair maker.'

EDIT - Sarah's siblings, Ann Elizabeth (born 29th September 1817) and Margaret Henrietta (born 18th October 1822), were baptised alongside her.
FURTHER EDIT - Looks like 29th June 1837 was a mass baptism of people who had not been baptised as infants.
