'Here is The Practical
Photographer description of this instrument
"A writer in 'The Photographic Times' of a month or so back mentions a
much needed improvement in the stereoscope, and regrets that such an
instrument is not yet to be had.
'All that is required' he says 'is an easily controlled uniform
simultaneous movement of lenticular prisms from or towards each other
through a very small distance, thus enabling each individual rapidly to
bring before each eye the combination of the particular pictures before
It is rather singular that almost simultaneously Mr AH Baird has
introduced his 'Lothian' Stereoscope, which possesses just those points
which Professor Himes, who writes the above, urges the need for.
The eye can be placed in close proximity to the lenses, and the broad
flange on the latter cuts off direct light. The carrier slides
easily to and fro on two tubes.
It is an instrument to be highly recommended, and one which is
calculated to assist many who find a preliminary difficulty in acquiring
proper stereoscopic visions.
