all respects a perfect camera, and takes a negative 2 by 14 inches, the reproduction as in Fig. I. being from one of the negatives. The camera carries in spoolform sufficient for twelve exposures, and when this is finished, the spool may, in daylight, be removed and a new one inserted.
Supposing it necessary to insert a new spool of film, which can be obtained put up in readiness for inserting in place, we must first get to the inside of the camera; this is. done by inserting the finger nail in a small bolt at the lower ‘portion of the front as in Fig. IL. and drawing it out

about + inch, when the camera body
may be lifted from its cover or box in the manner shown in Fig. ITT.
Fig. IL. At either side will
now be found two arms, which are intended to | hold the spools; these are swung outwards |
and the spool dropped into place, Fig. IV. The style in which the film is wound is akin to the method of wrapping fancy ribbons, that is, the ribbon and a strip of paper are wound together. Beyond the ends of the film will be found a certain length of opaque paper, this is undone and passed round the back of the
Fig. INI. camera at the focal plane and inserted in !
a slit on the bobbin at the other side. The camera can now be put in its cover or case and the small bolt closed. The key on top of camera should be turned about eighteen times when the Fig. I. will be seen through
a piece of
ruby celluloid at the back. This denotes
that the film is at the focal plane ready for exposure. Hach exposure is wound off in a similar manner at the back.
The method of setting and liberating the shutter for either instantaneous or time exposures, is controlled in a very ingenious manner by one small button. The shutter
is set by push

returns to its normal position by aspring, and is liberated by a slight pressure of the thumb as in Fig. V. For time = exposures it is requisite to give the button a quarter turn before setting the shutter. A finder is provided, and the instrument is covered in morocco and all objects at and beyond four feet are in focus.

BOTTLE CLIP.
Developing or other bottles can, by means of the new clip introduced by Messrs. Butcher be
Drevented from being knocked over in the
, dark, on board ship, or other places. The clips are nailed to any suitable wall or board, and when inserting a bottle in the clip it has only to be set on the ledge and pushed back, when the flexible steel arms will embrace it and hold it securely,
