_Mrs. Catherine Barton_ (Vol. iii., pp. 328. 434.).--When I answered the Query, I was not aware of what Baily states in the Supplement to Flamstead, p. 750. Rigaud ascertained for Baily that Mrs. C. B. (the title _Mistress_ being given at that period to marriageable young ladies) was not the _wife_, but the _sister_ of Colonel Barton. Both were the children of Hannah Smith, Newton's half-sister, and Robert Barton. Mrs. C. B. was born about 1680. M. * * * * * Miscellaneous. BOOKS AND ODD VOLUMES WANTED TO PURCHASE.
