Binomax Magnifier. 
For a great number of investigations in research and industrial laboratories, a microscope 
of the ordinary type is not satisfactory. Often a high magnifying power is not required and the 
objects under examination are not of a suitable shape for placing upon a microscope stage, nor 
is it convenient to prepare suitable microscopic sections. To fill this requirement we have produced 
the Binomax. It is a binocular magnifier giving magnifying powers of 4, 8, 16 and 32, and having 
a very wide field. Binocular vision is of great advantage over monocular, because the view given 
is natural and is similar to that seen by the eye except that it is on an enlarged scale. Thus the 
solidity, depth and true perspective are seen, which 
is invaluable for examining solid bodies and for 
dissecting. The Binomax is fitted to various stands, 
which are described and illustrated, and which are 
adapted for using the magnifier for different pur- 
poses. The uses to which this magnifier can be 
put are too numerous to detail, but a few may 
be mentioned. In medical work it is an excellent 
means of examining skin, hair and bone and makes 
a good corneal microscope, giving an erect image, 
and also is invaluable for dissecting work. Ina

and metal, and objects in stone, wood and meta! and 
specimens in troughs and cishes can readily be 
examined, The Binomax is without equal for 
examining parts of large objects, as by means of 
the stand with universal movement, the magnifier 
can be brought up to the object without the latter 
being moved. In other branches of work, dealing with such things as flaws in metal, brushwork 
in paintings, prints and engravings, fabrics and fibres, this magnifier is of the greatest service. 
In engineering shops, small machined parts are readily examined, and in many works where 
very fine precision turning is done, a Binomax with universal movements fitted to the lathe 
itself will prove of inestimable value. In dealing with small objects or for examining parts of 
large objects where there are no facilities for making regular microscope specimens, the Binomax 
is the most convenient and satisfactory form of microscope available. 
The Binomax consists of two complete microscope systems inclined to each other at the 
natural convergence of the eyes. Each system has a prismatic erecting arrangement. The interocular 
distance is adjusted by revolving the prism boxes. The method of obtaining the four powers witb 
only one pair of object glasses is a new one. The object glasses are held in tubular mounts witb
