uty of native coloration," or whether the statement is, as I
conclude Professor Hunt is inclined to believe, one of those hoaxes in
which many of our transatlantic friends take so much delight.

MATTER-OF-FACT.

_Photographs by artificial Lights_.--May I ask for references to any
manuals of photography, or papers in scientific journals, in which are
recorded any experiments that have been made with the view of obtaining
photographs by means of artificial lights? This is, I have no doubt, a
subject of interest to many who, like myself, are busily occupied during
the day, and have only their evenings for scientific pursuits: while it is
obvious, that if such a process can be successfully practised, there are
many objects--such as _prints_, _coins_, _seals_, _objects of natural
history and antiquity_--which might well be copied by it, even though
artificial light should prove far slower in its action than solar light.

Replies to Minor Queries.

_Vandyke in America_ (Vol. viii., p. 182.).--I would take the liberty of
asking MR. BALCH of Philadelphia whom he means by Col. Hill and Col. Byrd,
"worthies famous in English history, and whose portraits by Vandyke are now
on the James River?" I know of no Col. Hill or Byrd whom Vandyke could
possibly have painted. I should also like to know what proof there is that
the pictures, whomsoever they represent, are by _Vandyke_. MR. BALCH says
that he favours us with this information "_in answer to the query_" (Vol.
vii., p. 38.); but I beg leave to observe that it is by no means "in answer
to the query," which was about an _engraved_ portrait and not _picture_,
and {229} his thus bringing in the Vandykes _a propos de bottes_ makes me a
little curious about their authenticity.

_Title wanted--Choirochorographia_ (Vol. viii., p. 151.).--The full title
of the book inquired after is as follows:

"[Greek: Choirochorographia]: sive, Hoglandiae Descriptio.--Plaudite
_Porcelli Porcorum pigra Propago_ (Eleg. Poet.): Londini, Anno Domini
1709. Pretium 2^d," 8vo.

The printer, as appears from the advertisement at the end of the volume,
was Henry Hills. The middle of the title-page is occupied by a coarsely
executed woodcut, representing a boar with barbed instrument in his snout,
and similar instrument on a larger scale under the head, surmounted with
some rude characters, which I read
