The quotation should read: Fam.

Whisper it, sister! so and so! In a dark hint, soft and slow.
[47] The mother of Prince Arthur in Shakespeare's _King John_.

In the MS the words "the little Arthur" are written in pencil above the name of Constance.
[48] In _F of F--A_ this account of her plans is addressed to Diotima, and Mathilda's excuse for not detailing them is that they are too trivial to interest spirits no longer on earth; this is the only intrusion of the framework into Mathilda's narrative in _The Fields of Fancy_.

Mathilda's refusal to recount her stratagems, though the omission is a welcome one to the reader, may represent the flagging of Mary's invention.

Similarly in _Frankenstein_ she offers excuses for not explaining how the Monster was brought to life.
