PRACTICAL PHOTO-MICROGRAPHY. 
The stands chiefly intended and, in our opinion, best 
adapted for photo-micrography are those of Baker 
(Nelson model), Watson (tripod foot), Swift (Jackson- 
Lister, or Wales pattern), but, keeping in mind the 
remarks made in this chapter, the beginner need not 
fear to employ any really steady, well made stand. 
Fig. 4 shows a very good stand by Watson. It is a 
Student’s stand of the highest class, and, considering 
its design and fittings, is far from dear. 
Fig. 5 shows the stage of another good stand of the 
same firm. This, from its abnormally large stage, is 
specially adapted for examination and photography of 
“ plate-cultures,” and the like. 
Fig. 6 shows a stand by Swift, specially well- 
adapted for photo-micrography; it is called the ‘‘Histo¬ 
logical ” stand. We choose the horizontal position to 
show the evident stability of the instrument in the 
position required for most of our work. 
Fig. 7 is a cheaper stand by Beck, also suitable. 
It is known as the “ London ” microscope, and has 
several good points for our branch of work. Messrs. 
Beck have worked out a remarkably handy mechanical 
stage, which can be attached to the stand at will. It 
has an unusual amount of “ play ” in both directions, 
and so is suitable for large preparations that require 
careful examination all over.
