THE NORWICH FILM.
A New Gelstine Patent to be Manu-
featured at Randolph.

A New GeIatIne Patent to be Manu-
featured at Randolph.
Prof. Ozias Dodge OF Norwich, Conn.,,
an artist of note and one of the directors
of the Metropolitan museum OF New
York city, has just patented gelatine
film of great value in photography, lith-
ographing, etching and kindred lines of
work, and has selected the Brigham Sheet
Gelatine factory in this village for its
manufacture.
Professor lodge was in Randolph all
OF last week engaged with Mr.. Brigham
in making arrangements for the manu-
facture OF the film and placing affairs
connected With it on Q business basis.
He expressed great satisfaction with the
equipment and work of the factory
and the excellent atmospheric condi-
tions of its location. Being a chemist as
well as an artist, he analysed the village
water supply, just as it was drawn from
the faucet, and pronounced it purer than
the Croton water OF New York after it is
filtered and distilled. In fact, he said
the Randolph water was too pure for q
chemist to find any fun in Analysing it.
The Norwich film is a sheet of trans
parent gelatine cast upon hand-ground
plate glass OF different textures for the va
rious kinds OF drawings, tracings, etc.
Unlike all tracing papers, it is fibreless
and colorless and offers no obstruction to
the actinic rays of light in making photo
graphic prints, after the drawing is made
and fixed. The composition of the gela-
tine is such that it takes and holds the
slightest mark of the pencil, yet allows
of clean erasure with soft rubber. 1t is
made in three textures velvet, medium
and coarse, and three special compost
tions.
The Universal is suited to all kinds of
! work other than photographic. The
smooth side has waterproof coating,
and when the drawing is completed and
flowed with fixatif it is held upon a per-
fectly transparent flexible support be-
tween water-proofed coatings. 1t is per-
manent and can be used indefinitely.
The Lithographic is made thicker, and
without the waterproof back for conven-
fence in transferring and, with q slight
amount of acid in the composition, CIV
| ing sharp, clean transfers without the
necessity of "gumming in" upon the
stone.
| The Photographic is made in the velvet
grade only and is extremely thin to be
reversed without giving double lines in
connection with q negative. 1t is used
! to add sky effects, detail or retouching
of any kind. 1t should not be flowed
, with fixatif as the ground effect in con-
nection with the negative produces just
the shading needed in printing. 1t can
also be used to advantage for fine pen
work, reproduced directly upon the plate
for line work, or fine detail blue print
work.
| The velvet, medium and coarse sheets
have precisely the same surface as the
| photographic stone, retaining every touch
of the photographic pencil sin situ." 1t
is entirely transparent, therefore q clean
tracing can be made from a faint copy.
1t gives the same effects with the scraper
as the stone. The fine grained sheet is
| far superior to smooth gelatine for iith-
ographic and all forms OF pen work.
1t makes a perfect transfer to either
stone or zinc, and is the ideal drawing
surface.
No etcher Eill ever use smooth sheet
of gelatine after once having tried the
/ grained. 1t is light, flexible, entirely
transparent, and all pencils are used upon
it, producing all effects required. The
drawing can be erased with soft kneeded
rubber without injuring the surface, or
| can be scraped with sharp knife for
7 clear high lights; and, finally, the draw
ing can be made indestructible by how-
! ing with collodion, becoming thereby
Photographic positive, from which prints
can be made upon any Photographic
paper. 1t may also Q used directly upon
the copper plate by the Dodge process.
The velvet sheet is best for small intri-
cate designs OF jewelry, details Of furni-
ture, pottery, etc. After the drawing is
