For a mystic charm, one of the strongest known is the hand of an unbaptized infant fresh taken from the grave in the name of the Evil One.

A dead hand is esteemed also a certain cure for most diseases, and many a time sick people have been brought to a house where a corpse lay that the hand of the dead might be laid on them.

The souls of the dead who may happen to die abroad, greatly desire to rest in Ireland. And the relations deem it their duty to bring back the body to be laid in Irish earth. But even then the dead will not rest peaceably unless laid with their forefathers and their own people, and not amongst strangers.

A young girl happened to die of a fever while away on a visit to some friends, and her father thought it safer not to bring her home, but to have her buried in the nearest churchyard. However, a few nights after his return home, he was awakened by a mournful wail at the window, and a voice cried, “I am alone; I am alone; I am alone!” Then the poor father knew well what it meant, and he prayed in the name of God that the spirit of his dead child might rest in peace until the morning. And when the day broke he arose and set off to the strange burial ground, and there he drew the coffin from the earth, and had it carried all the way back from Cork to Mayo; and after he had laid the dead in the old graveyard beside his people and his kindred, the spirit of his child had rest, and the mournful cry was no more heard in the night.

The corner of a sheet that has wrapped a corpse is a cure for headache if tied round the head.

The ends of candles used at wakes are of great efficacy in curing burns.

A piece of linen wrap taken from a corpse will cure the swelling of a limb if tied round the part affected.

It is believed that the spirit of the dead last buried has to watch in the churchyard until another corpse is laid there; or has to perform menial offices in the spirit world, such as carrying wood and water until the next spirit comes from earth. They are also sent on messages to earth, chiefly to announce the coming death of some relative, and at this they are glad, for then their time of peace and rest will come at last.

If any one stumbles at a grave it is a bad omen; but if he falls and touches the clay, he will assuredly die before the year is out.
