CALOTYPE PORTRAITS.

(_By Licence of the Patentee._)

MR. PHILIP DELAMOTTE begs to announce that he has concluded an
arrangement with the Patentee, Mr. H. F. Talbot, which enables him to
take Portraits by the newly-discovered Collodion Process. The advantages
which this process offers are,--Excellence of Likeness, great
Convenience, and the opportunity of Multiplying copies of the same
Portrait to any extent. These Portraits have the appearance of beautiful
mezzotint engravings, with the superior accuracy which Sun-painting must
insure. One moment suffices to obtain the likeness, and no constrained
position is required. Hence a happy expression of face is instantly
caught, and young children may be taken without difficulty. To those who
wish for several copies of the same Portrait, the Calotype offers every
facility, as an unlimited number of impressions may be printed, by the
agency of the sun, from the glass plate. These will all be exactly equal
to the first, and may be had at a moderate cost.

TO ARTISTS AND SCULPTORS.

MR. DELAMOTTE will be happy to photograph Artist' Paintings and Statues,
and supply two or more impressions as may be desired. He also undertakes
to photograph, under the superintendence of the Artist, the Life Model,
