Anthony's Patent Triplex
Tripod.
-Ja HIS is the finest finished in the market
I and perfectly rigid, combining both the
folding and telescopic, besicles rvhich it occupies
little space, and for transportation can be
packed with clpthing in a large grip sack. It
is made of cherry throughout, and has the
patent springs on under side of top, by which
it is impossible for the legs to become un-
fastened accidentally. When the leg is fully
extended, it is held automatically by a spring,
saving necessity of using thumb screrv for
clamping same.

are of such quality and capacity that they mark an THESE-le.nses
r epoch in the construction of photographic objectives. They are
the invention of Alvan G. Clark, the celebt"t.d manufacturer of tele-
scopes,and are of a construction dissimilar from anvthing heretofore
followed, and are as striking in their results as Mr. Clark's successin the
telescopeobjectives has been.
(Full Size,6r/2x8/2,A. G. C.)
These lenses may be used with equal facility in three directions:
r. To all work to which the rapid rectilinear type may be adapted,
when they give an angle of about 6o degrees, and in whicir capacity we
enumerate them under List No. r.
z. To all work requiring a medium angle objective, as enumerated.
under List No. z.
3. when they may be used as rn,ide angle objectives, having an aper-
ture of nearly roo degrees, and as such they may be used w-ith larger
stop than any other specially constructed wide angle lenses. They are
quite free from marginal distortion and magnified perspective, so com_
mon to lenses of this class. As wide angle lenses they aie quoted under
List No. 3. when using these lenses in this capacity, caie should be
used in beveling the back of the front board, so as to allow free passage
of the rays.
The lenses are uncemented, each lens of the combination being
mounted for itself, and are therefore free from danger of graduat de-
crease in speed, so common in many lenses, owing to tile chemical
change in the cement. The crown glass is on the outside, and therefore
less liable to become scratched. The mountings are unusually compact,
and each mounting has engraved upon it Mr. clark's autograph as well
as our firm name.

Dallmeyer's Lenses.
extraordinary unanimity of opinion regarding the excellenceof l-HE
I Mr. Dallmeyer's lenses both in Europe and America, is one of the
most gratifying evidences of their great superiority. There is not a
photographer of any note on either side of the Atlantic who is not the
possessor of one or more-some can count them by the d}vsn-axd the
difference in cost between these and the inferior ones is very slight,
when their great superiority is considered. None others approach them,
and they have long been justly held to be the most indispensable of all
the requisites of the art.
In the quality of the glassused; inthe perfectionof finishand adjust-
ment; in softness, crispness and depth ; in rapidity, delicacy and every
quality a lens should possess, the Dallmeyer lenses are unrivaled. With
or without diaphragms, they are better adapted to the particular work
in hand than any others ever made, and every kind of photographic re-
quirement is provided for. Before purchasing, carefuily read the infor-
mation contained in the catalogue, particularly that regarding the series
of rapid rectilinear and the wide angle rectilinear.
The first requirement in making photographs of great merit, whether
for portraiture, landscapes, architectural vier,vs, or copying, is a lens that
in skilled hands prornises the very best results. Those who excel uni-
formly select Dallmeyer lenses and pronounce them indispensable.
The PetsNIr PonTRAIT combinations have an adjustment of the back
lens by which a diffusion of focus or depth of definition is obtai;red.
This is not found in any other make. They also have a full set of the
Waterhouse diaphragms in morocco cases.
Mr. Dallmeyer's line of lenses is the most complete of any in market,
embracing everything that can be wanted for any possible operation.
Dallmeyer's Wide-Angle Rectilinear Lenses.*
(Patent.)
HESE LENSES embrace angles of pictures from 9o to roo deg.,
and enable photographers to take views of buildings, interiors,
etc., in confined situations, where lenses of
longer focus cannot be used, and where abso-
lute rectitude of lines is imperative.
The wide-angle rectilinear lens has the fol-
lowing advantages over existing non-distorting
double combination lenses : It is entirely frec
from a central spot. It can be used rvith u
larger stop, i. e., it is quicker in action. it

The lenses are mounted in rigid settings or tubes, and each is fur-
nished with a rotating diaphragm plate. In the column below, the
largest size of plate covered by each lens is recorded ; and if microscopic
definition up to the corners be required the smallest or smallest but one

(Patent.)
RAPID RECTILINEAR LENS is emphatically " The Lens " 1-HE
-1, for all kinds of outdoor photography. It works at an intensity of
$, and, although not so rapid as the D Lens, requiring nearly double the
exposure , is su1lerior to it for views because of its
having only four, instead of six, reflecting sur-
faces. It is composed of two exactly symmet-
rical cemented combinations, and unlike most
existing double combination cemented lenses,
requiring small stops to cure the inherent exces-
sive spherical aberration, the Rapid Rectilinear
is aplanatic, i. a., it works with the full opening.
Hence its superiority for al1 kinds of- quick out'
door pictures, groups, instantaneous effects,
landscapes, architectural subjects, or for dimly-
lighted interiors. For copying and enlarging
this lens is unrivalled. With smaller stops each
lens covers the next larger, or even two sizes larger plates than those
record.ed, thus embracing angles of pictures from sixty to eigirty degrees
and this without any trace of flare or central spot. Many fine large

is a single combination landscape lens, working at an intensityTHIS
I of 11s,and is the best lens for landscapes, pure and simple, em-
bracing large angles. Being a single combination, like the rapid land-
scape, it has but tzuo reflecting surfaces and therefore produces a more
brilliant picture than the wide-angle multiple lenses. It works with a
proportionally large stop, i. e., it is quicker in action and the illumina-
tion is rnore equally distributed from the center to the margin of the
plate. Being composed of.tltree lenses cemented together it is superior
to the old Meniscus, composed of fuuo,inasmuch as it produces less dis-
tortion, gives better marginal definition and is of much smaller size.

through which the light is allowed, to passaia the tube, which is placed
on the ground glass in the same way that a focusing glass would

Anthony's Climax Shutter.
-nHE shutter is attached to the lens tube by means of a metal collar,
r that is provided with a binding screw to hold it firmly in place.
The shutter consists of a wooden casing, with facing of hard rubber,
inside of which is a hard rubber slide, having an aperture corresponding
in size to the aperture in the cas-
irg. This slide runs very easily
in the grooves in wooden casing,
and admits of a very rapid expos-
ure when the shutter is set at full
speed. The shutter is set by turn-
ing (tozuardst/te right) the milled
screw at the left hand side of back.
The speed can be regulated at
will by drawing out or pushing in
the brass pull, seen in the cut, at
lower left hand side of shutter, a
binding screw at the left serving
to hold this pull at any desired
distance, thus perfectly regulating
the speed.
For time exposures the shutter"
should be set at slow speed,and the
Iittle brass piece on top of shutter at the left hand side (see cut), so ad-
justed as to allow the long arm of the trigger to reach down as far as it
will go, thereby engaging rvith the lower pin on the slide at the moment

movable collar, which, by the .rse of three turn scrervs, may be made eitherF larger or smaller, so that it rs adjustable to any ordinary lens.
By very simple and ingenious device, this shutter is changed from
" long time exposure to the most rapid instantaneous working, all that is
needed to effect the change being the adjustment of a metal catch.
It is provided with Pneumatic Release which works either time
or instantaneous movement, and for the former is unlike most other
shutters in use, inasmuch as the bulb must be compressed for opening
the shutter and again compressed for closing it; a metal catch dropping
and holding it open until released by the second pressure of bulb, whether
for long or short time. The shutter responds instantly to the com-
pression of the bulb, thus giving the operator perfect control of his
exposure.
It is compact, light and simple in construction, easily worked and
of fine appearance, and each shutter is neatly packed in a small
mahogany case, which will readily fit into the pocket.
The price of this shutter, with bulb and rubber tube, is $a.5o.

Diaphragm Shutter.
T I M E A N D I NS TANTANE OUS . WITH SIL ENT T IM E AT T ACHM ENT .
-TtHE advantages of the principles involved in the Diaphragm
I Shutter are so apparent that they have from the outset
been fully appreciated.-for It requires little argument to show that the
proper place opening and closing a S_hutter is _in the- optical axis of
the Lens, and in both time and
instantaneous photography, it is
evident that this Shutter, starting
its opening with a pin hole and
gradually increasing to the size of
stop for which it is set, and returning
in the same manner, will give the
effect of a small stop, i.t., more
depth and flatness.
The makers have taken advantage
of all the improvements, and offer 'qo the Model with the confidence
that it meets every condition. While
the Shutter is in itself a nice piece
of mechanism, the workmanship and
finish are of the highest order.
The advantages of this Shutter
over others are as follows: 'fhere are no loose stops. The
variatiorr in size of stop is made by
turning the black disk, which is
supplied with a large index. Ab-
solute control of time exposure.
Large index giving correct indica-
tion of time, in seconds and fractions
thereof. Entire independence of
speed regulation from the influence
of temperature or humidity. By
(Cut two-thirds of actual 5 x 8 size.) turning a lever it is set for either
time or instantaneous exposure, and remains so until changed. The
movement during exposure is almost absolutely free from concussion.
The blades are changed from steel to hard rubber, so that there is no
danger from rust. All parts rvhich must be manipulated are placed at
the front, easy of access. We guarantee that the Shutters and barrels
are absolutely true and optically centered, whether arranged for our

to the camera and front, the use of which is obvious, your attention is
called to the apparatus for illumination, which is by all odds the most
important feature of any enlarging lantern.
The lamp, which is intended for use with kerosene, is provided with
a double-wick burner, both flames emerging through a single aperture
in the dome. This feature increases the volume of light two-fold; the
burner is provided with a close-fitting chimney-base fitted with an aper-
ture covered with non-actinic glass, intended both for dark room illu-
mination and also for observing the height of the flames. A conical
light conductor connects the lamp with the condensing lenses, and is
made to telescope so as to adjust the light accurately to the focus of the
condensers ; this light conductor has an aperture at the side covered
with a movable metallic disk, and is intended to admit of the operator
finding the centering point of his flame on the condensers ; this he will
see at a glance by the.reflector. The lamp is not rigid, but can be re-
volved so as to bring the flame in any desired position. Some negatives
require a more intense light than others, and experience will show how
to arrange the light for any particular occasion.
The form of this lantern is such that all heat passes upward.s through
the chimney, and as there is no boxing around the apparatus it is always
cool, and all risk of breaking lenses or negatives is avoided. Ther
change from the use of artificial light to daylight is better shown in the
cut than described in writing. With this lantern and a half-inch stop in
a half.-size portrait lens, life-sized enlargements from cabinet negatives
may be easily made with Anthony's Reliable Bromide Paper in from
thirty-five seconds to one minute, according to density of negative.
. Cooper Lantern as transformed into a .DoyliglttEnlarging Camera.
The design of this lantern is the result of long practical experience
u'ith various methods of illumination for enlarging, and we can guarantee
its giving results as perfect as the electric light at a cost that makes
comparison ridiculous. This lantern is also admirably suited for slide
projection, and is therefore of double value to societies and colleges.

Fon DavLTGHT ENr-ancrrvc.-Remove the lamp and condensers, rack
the front inward as far as it will come, then raise the back of the bellows-
bearing frame from its position to the back cf the bed-board on which
it will be securely held by the screw heads which fit into the key-hole
slots corresponding. Remove the front in the same way and set it back
onthescrews designed for it, rvhich will be found on the movable bed
operated by the rack work. Attach the ground-glass frame to the back
and the instrument is ready for use. A dark room with an aperture in
the window allowing the ground glass end to fit firmly so as to exclude
all outside light, but allowing an unobstructed view of the sky, is the
most satisfactory.
If you cannot get a clear view gf. the sky use a mirror at a proper
angle to reflect'the sky above. White card-board reflectors may be used,
but nothing equals the mirror. A shelf should be fastened to the win-
dow to support the weight of the camera.
