_Cameras._--At one of the earliest meetings of the Photographic Society, I
suggested the use of papier maché as a material for the construction of
cameras, as possessing _nearly_ all the requisite qualities; but there is
one serious objection to its application to this purpose, its
_brittleness_, as a smart blow is apt to snap it like a biscuit. I think,
however, upon the whole, that if a peculiar kind of _Honduras_ mahogany,
such as is used for coach panels, is adopted, the possessor would never
desire a change. It should be as plain as a piece of deal, without the
slightest beauty of grain, which is positive detriment to a camera, from
the accompanying liability to warping.
