POPULAR SCIENCE REVIEW. 
International Exhibition. Messrs. Bedford, England, Mudd, Thurston, 
Thompson, and Robinson were each awarded a silver medal for landscape 
photographs. Figure and portrait photographers were not recognised as 
worthy the silver medals, and therefore received medals in bronze. The 
names of those thus distinguished are Messrs. Blanchard and Mayall, the 
latter award being for enlargements from small negatives. Bronze medals 
were also awarded to Messrs. Grigg3, Col. Briggs, Bourne and Shepherd, 
Macfarlane, Heath, Col. Stuart Wortley, and White, for landscape photo- 
graphy. For cabinet work a bronze medal was awarded to Meagher, and 
for lenses to Mr. T. Ross ; Mr. Cherril received a bronze medal for carbon 
prints, Caldesi one for medallion photographs, and M. Joubert one for his 
enamel process. A silver medal was awarded to Mr. Swan for an improved 
carbon -printing process, to Mr. Woodbury for a new mode of printing, and 
to Mr. Dallmeyer for a triplet object-glass. The following names were 
associated with “ honourable mention ” : — Beasley, Bean, Brownrigg, 
Cameron, Coghill, Cramb, Cruttenden, Grisdale, Hemphill, Hosmer the 
Pantoscopic Company, Pouncy, Ross (of Edinburgh), Rouch, Royal Artil- 
lery, Soloman, H. Swann, Thomas, S. Thompson, Verschoyle, Wardlv, and 
Wilson. There have been, as was to be expected, perhaps, many charges 
of unfairness and undue partiality brought forward in connection with these 
awards, and some very striking inconsistencies have been noted ; but the 
worst case published is that which Mr. Thomas Ross has called public 
attention to, viz., the jurors deciding upon giving a medal for excellence 
in lenses which they had not examined, simply because they were exhibited 
by a manufacturer of known repute. This medal, the only one awarded for 
general excellence in photographic lenses, Mr. Ross generously declined to 
receive, upon the ground of the injustice of a mode of proceeding which 
deprived every young and unknown optician of that fair chance in honour- 
able competition which each exhibitor has a right to demand and to expect. 
Photography at the British Association . — Photography has not played a 
very prominent part at the meeting at Dundee, although its productions 
were used to illustrate papers in most of the sections. Professor J. C. 
Maxwell, F.R.S., introduced a new stereoscope in section A. The effect of 
looking through this instrument was very novel and striking. In the ordi- 
nary stereoscope the observer applies his eyes to the two lenses, seeing one 
picture with the left, and the other with the right eye. In Professor Max- 
well’s the observer stands a short distance from the apparatus and looks 
with both eyes through the large lens. The instrument consists of a board 
about two feet long, on which is placed — 1. A vertical frame, to hold the 
side turned upside down. 2. A sliding piece near the middle of the board, 
containing two lenses of six inches focal length placed side by side, with 
their centres about 1| inch apart. 3. A frame containing a lens of about 
eight inches focal length and three inches diameter. The eye should be 
placed about two feet from the large lens. With his right eye he sees the 
real image of the left-hand picture formed by the left-hand lens in the air, 
close to the large lens, and with the left eye he sees the real image of the 
other picture formed by the other lens in the same place. The image may 
be magnified or diminished at pleasure by sliding the piece cont a i nin g the 
two lenses nearer to or farther from the pictures. '
