To Know if a Child New-Born shall Live or Not (Spell)

From Madam Le Marchand's Fortune Teller and Dreamers' Dictionary:

To Know if a Child New-Born shall Live or Not

Write the proper names of the father and mother, and of the day the child was born, and put to each letter its number, as you did before, and unto the total sum, being collected together, put twenty-five, and then divide the whole by seven; and then, if it be even, the child shall die; but if it be uneven, the child shall live.
