l side of the eye.Two pictures are taken, one with the tube on a levelwith the two balls, the other with the tube somewhatbelow the level. The location of the foreign body withreference to the balls in each negative is platted upona chart and its position is accurately located. This ap-paratus has not proven satisfactory in my hands for sev-eral reasons : First—It is a difficult matter to strap theapparatus firmly enough to the head, without making ituncomfortable for the patient. Second—The patientmust sit in a chair or lie on his back, and I find it almostimpossible for the patient to hold his head still longenough for a proper exposure. Third—The apparatuscannot be used with the compression cylinder diaphragm.Fourth—In changing plates the position of the apparatusis apt to be disturbed. A device was needed wherebythe patient could lie down, the head being firmly heldwith sand bags, the compression cylinder could be used,and the plates could be changed without disturbing the

It was to meet these conditions that I madethis new apparatus. The compression cylinder table which I use is theone manufactured by Kelly-Koett. The patient lies uponthis table with the side of his head resting upon a plateholder which consists of a small table, 4 inches highand 14x17 inches square. In the top of this small table,upon which the patients head rests, is an opening 8x10inches, which is guarded by a piece of celluloid. Theplate is placed in this opening from underneath, and isheld against the celluloid by a trap door. This plateholder table is large enough to allow plenty of room forsand bags to hold the patients head absolutely quiet. Inplacing these sand bags two large ones (not too full ofsand) are apolied at the back and top of the head, and athird, somewhat smaller, is placed on the side of the head. The
