It should be so constructed as to makepossible illumination from below upwards,either in its entirety or in part. 4. It should be tunnelled for stereoscopicwork. 5. The plate holder for tunnel work shouldhold either a plate in an envelope or a screenin a holder. 6. The top should be capable of horizontaladjustment for use in vertical stereoscopicexposures. 7. The entire table should be freely mov-able, yet capable of fixation to the Fig. 162.—^^all-folding table. A combination of stand and table, as onepiece of apparatus, has certain advantages, asregards the possibility of obtaining more cer-tain and firm compression and as regardseconomy in floor space, but the very flexibility of the isolated units gives them a great advan-tage. A table arranged to fold against tiie walland to work in combination with a stereo-scopic tube stand, is an instrument of con-venience where space is limited (Fig. 162). The table top is made of five ply built upveneer, quartered oak outside, 6 1 x 24,hinged at one end, so that it can be closed upagainst the wall, the lower side being equippedwith a special counterbalanced frame to ac-commodate 17 X 17 cassettes; this table isequipped with folding legs arrartged to auto-matically drop and support the table when itis placed in the horizontal position and to besufficiently strong to support the table withthe patient lying th
