Mary Moore sends for physicians from Berwick the morning of Candlemas, who come along Lady Selby, Widow Fenwich and other friends to witness Mary Muschamp's fits. Muschamp, after suffering torments until late the previous night, awakens early to find she still lacks the use of her limbs, tongue and stomach. She signs to the onlookers that her senses are intact, but her jaws are closed to both speech and nourishment. The doctors are unable to assist, and Muschamp insists through gestures that "God had layd it on her, and God would take it off her."(2-3)

Margaret Muschamp begs Mr. Balsom, Mr. Strother and Mr. Huet to pray for her while Mary Moore "to her great expences neglected no lawfull meanes that could be used" to help her daughter. Muschamp nevertheless has another tormenting fit around noon, lasting an hour.(3)

Margaret Muschamp allegedly suffers from tormenting fits for the 16 weeks between Candlemas and Whitson (Pentecost) Eve. During this time, she sleeps soundly at night, but her torments begin anew upon waking. At first, the fits last three or four hours, but over time this increases to eight hours a day. The fits are described as "every houre a severall torment, such strong cruell ones that cannot be exprest, as many with weping eyes beheld it." Ministers pray over the girl, but expect only her death to end her suffering. Sir William Selby, Lady Selby, Countess Lendrik, Lady Haggarston and others all observe at various times.(3)

Margaret Muschamp, during the 16 weeks between Candlemas and Whitson (Pentecost) Eve, is often seen to smile and sign that she feels no pain as soon as her tormenting fits have ended for the day. She habitually sits quietly for the remainder of the day.(3)

Margaret Muschamp allegedly fasts during the 16 weeks between Candlemas and Whitson (Pentecost) Eve. After her fits have ended each day, "she onely we wet her lips with a little milke and water; for nothing she would let come within her jawes." Muschamp claims, through signing, that "God fed her with Angels food" and she is not seen to lose any weight for the duration.(3)
