_Vincent Family_ (Vol. vii., pp. 501. 586.).--The _Memoir of Augustine
Vincent_, referred to by MR. MARTIN, was written by the late Sir N. Harris
Nicolas, and published by Pickering in 1827, crown 8vo. Shortly after its
publication, a few pages of _Addenda_ were printed in consequence of some
information communicated by the Rev. Joseph Hunter, respecting the
descendants of Augustine Vincent. At that time Francis Offley Edmunds,
Esq., of Westborough, was his representative.

_Judge Smith_ (Vol. vii., pp. 463. 508.).--I am well acquainted with the
monumental inscriptions in Chesterfield Church, but I do not recollect one
to the memory of Judge Smith.

Thomas Smith, who was an attorney in Sheffield, and died in 1774, had a
brother, William Smith of Norwich, who died in 1801. Thomas Smith married
Susan Battie, by whom he had a son Thomas Smith of Sheffield, and after of
Dunston Hall, who married in 1791 Elizabeth Mary, only surviving child of
Robert Mower of Woodseats, Esq., (by Elizabeth his wife, daughter of
Richard Milnes of Dunston Hall, Esq.) It was through this lady that the
Dunston estate came to the Smiths by the will of her uncle Mr. Milnes. Mr.
Smith died in 1811, having had issue by her (who married secondly John
Frederick Smith, Esq., of London) three sons and several daughters. The
second son (Rev. Wm. Smith of Dunston Hall) died in 1841, leaving male
issue; but I am not aware of the death of either of the others. The family
had a grant of arms in 1816. Dunston Hall had belonged to the Milnes family
for about a century.

_"Dimidiation" in Impalements_ (Vol. vii., p. 548.).--In reply to your
correspondent's Query as to _dimidiation_, he will find that this was the
most ancient form of impalement. Its manifest inconvenience no doubt at
last banished it. Guillim (ed. 1724) says, at p. 425.:

"It was an ancient way of impaling, to take half the husband's coat,
and with that to joyn as much of the wife's; as appeareth in an old
roll, wherein three lions, being the arms of _England_, are dimidiated
and impaled with half the pales of Arragon. The like hath been
practised with quartered coats by leaving out half of them."

On p. 426. he gives the example of Mary, Henry VIII.'s sister, and her
husband Louis XII. of Fran
