_Portable Camera_ (Vol. vii., p. 71.).--If India rubber should turn out to
be what H. Y. W. N. thinks he has found it to be, it would be capable of
being turned to excellent account. For instance, instead of having a single
"portable camera," which is on many accounts very awkward to use, why
should not the tourist have a light framework constructed, and covered
entirely with this India rubber: in fact, an India rubber box, in which his
camera, and a partitioned shelf containing his collodion, developing fluid,
hypo-soda solution, &c., might be easily packed, and in which, by the aid
of sleeves, &c., he might coat his plates, and develop and fix them, quite
apart from his camera? He _must_ have _something_ to pack his camera, &c.
in; and the above-described packing-case would be very light, and also
waterproof.
