HOW TO ADMINISTER BAPTISM.
PROVIDED an infant is in danger of dying before a Priest can be procured, any other person, whether man, woman, or child, may baptize it in the following manner:
Whilst pouring common water on the head of the infant, pronounce the words, “I baptize thee in the name of the Father, and of the Son, and of the Holy Ghost.” The water must be common and natural water, and must be poured on by the same person who repeats the words; and care must be taken to repeat the words exactly, and to pronounce them at the same time that the water is poured on.
