New Catalogue of Projection 
Apparatus. 
It is particularly satisfactory to us 
to call attention to the new catalogue 
of projection apparatus issued by the 
Bausch & Lomb Optical Company be- 
cause it is a delight to any one inter- 
ested in lantern slide, opaque, micro- 
scopical and chemical projection. It 
is a complete textbook on the subject, 
showing a wide range of thoroughly 
effective apparatus.

What will the 
negative show? 
There’s density and definition; detail in 
high lights and shadows; correctness of 
perspective; color value — consider all 
these. For the negative can show only 
what the lens throws upon it. And any 
picture worth taking at all is worth tak-

PHOTOGRAPHIC LENSES 
In poor light — cloudy or rainy outdoors, 
on porches or indoors — good snapshots 
— better than many a time exposure — can 
be made easily through Bausch & Lomb 
Tessar Anastigmats (Ic, f:4.5 or lib 
f:6.3). And in bright sunlight they stop 
the fastest action blurlessly. 
Ask your dealer to put Tessar 
Anasitigmat on your camera. 
Then you will see how pleasur- 
able photography can be.
