N.B.—Place the bottle in warm water while the gallic acid

The paper cut in pieces a little larger than the 
size of the frame, is suffered to imbibe solution A 
in the same manner as described at page 125. It 
must then be hung np till dry. 
It may be kept in a dry portfolio, and will not 
be injured by exposure to light. 
N.B.—The prepared side must he marked in one of the 
corners. 
Taking the Picture. 
The camera is fixed on the stand, and the lens 
focussed until a perfectly distinct picture appears 
on the ground glass (or, in the case of an ordinary 
instrument, the ground glass frame must be re¬ 
moved after focussing); which must then he drawn 
into the upper part of the camera. • 
Its position, on the stand being noted, the 
camera is taken to the dark room (when the frame 
is separate from the camera, the frame only need 
be removed), where a piece of the previously iodized 
paper is floated on solution B; after five minutes 
Having covered the lens by means of the stop, 
the camera (or frame) is removed to the stand ; j 
and, being placed in position, the cap is withdrawn; 
or, in the case of a distinct frame, the slide in the 
back pulled up for a period, varying with the in¬ 
tensity of the light, of from five to twenty minutes. ! 
The proper time of exposure will be ascertained 
by practice. 
The picture taken, the lens is again stopped, 
the slide shut down, and the instrument re¬ 
moved to the dark room. The paper is then j 
floated with its prepared side on solution C until 
the image developes itself with intensity. 
When sufficiently intense, the photograph is 
washed ; then fixed by soaking in the solution of j 
hyposulphate of soda (solution d) till the yellows 
of the picture arc changed to a clear white; then 
wash well in water. 
This produces a negative photograph; that is, 1 
the natural lights and shades are reversed. 
To produce a positive picture the negative is j
