"Miasms arising from churchyards are in general too much diluted by the surrounding air to strike the neighbouring inhabitants with sudden and severe disease, yet they may materially injure the health, and the evidence appears to me to be decisive that they often do so. Among others who sometimes obviously suffer from this cause, are the families of clergymen, when, as occasionally happens, the vicarage or rectory is situated very close to a full church-yard. I myself know one such clergyman's family, whose dwelling-house is so close to an extremely full churchyard, that a very disagreeable smell from the graves is always perceptible in some of the sitting and sleeping rooms. The mother of this family states that she has never had a day's health since she has resided in this house, and that her children are always ailing ; and their ill health is attributed, both by the family and their medical friends, to the offensive exhalations from the Churchyard."
