the giant increases in almost geometrical ratio. Only small splinters which can be actually touched by the magnet, are suitable for the use of the small magnet, the large being necessary for all others. Ilaab, who intro- duced the latter, uses it for all cases. It is wise to

either (1) bring the eye close to the magnet before start- ing the current and increase its power very slowly, or (2; bring the eye from a considerable distance toward the point of the magnet with full current very gradually. Where the current cannot be regulated, the latter method only can be adopted. If the splinter gets im- bedded in the ciliary body or iris, the other pole of the

magnet can be used if it bo a double-ended magnet, or a strabismus hook can ba passed in and made to draw the splinter away from its posit'on in the desired direction. The failure of the magnet in Baab's practice, where

it has failed he attributes to (1) firm fixation of the splin- ter in the posterior walls of the eyeball, (2) firm fixation in the ciliary body, (3) fixation in a fibrinous exudate, (4) splinter healed over in the lapse of months. In 165

operations in ten years Haab reports 23 failures, 39 eyes were enucleated, nine had lingering cyclitis, 19 were saved from inflammation but were sightless. Of 71 cataracts extracted, 51 had good vision. The X-rays and the sideroscopo have much increased our powers of localization and aided the magnet."
