T h e conjunctiva is then closed in the conventional manner. It should be noted that if one does not desire advancement and prefers, instead, the security of a whip stitch, the suture may be inserted in the reverse order ; that is, through

T h e upper and lower marginal sutures then may be whipped once through the tendon before inserting all three needles through the muscle stump. This suture has given excellent results in my hands over the past 12 months. 2065 Adelbert Road (6).

New York During the last few years a good many kinds of specialized scissors have been de signed for particular maneuvers used in eye surgery. T h e surgeon often requires two pairs of scissors to complete a section ; such, * From the Department of Ophthalmology, St. Vincent's Hospital, The New York Eye and Ear In firmary, and New York University Post-Graduate Medical School.

for example, as right- and left-handed scis sors for performing cataract incisions. I have thought of combining two such pairs of scissors into one instrument, which would eliminate the confusion that sometimes arises when at a critical moment the surgeon finds that, instead of a set including right- and left-handed scissors, he has two pairs of lefthanded or two pairs of right-handed scissors. By using a spring-action mechanism two such pairs of scissors can be combined, as illustrated in Figure 1* designed for cataract t This instrument is manufactured by E. B.

A HAND REST FOR TUDOR-THOMAS METAL STAND* P. K. BASU.t D.O.M.S., AND H. L. ORMSBY,

Toronto, Ontario Fig. 1 (Castroviejo). Combination of right- and left-handed scissors for enlarging cataract incisions.
Fig. 2 (Castroviejo). Combination Westcott scis sors (A) with sharp points for delicate dissection and the removal of sutures; (B) with blunt points for general utility work.
incisions. Other sets may be made combining two different types of scissors used for other special purposes. One set could be made for iridectomy and iridotomy. Another could be planned for square grafts with the blades at one end of the same length and at the other with the blade which is introduced into the anterior chamber longer than the other and spatulated to minimize trauma to intraocular structures such as the lens or iris. A third set could be designed to complete the section in circular keratoplasties ; one end of this set could have blunt and the other sharp points. Another set might combine two pairs of Westcott scissors (fig. 2 ) , one with blunt points (fig. 2-B) for general utility, and the other with sharp points (fig. 2-A) for deli cate dissections and the removal of sutures. Still other sets could be designed for other special purposes. 9 East 91st Street (28).
To facilitate the removal of a graft from the donor eye, a hand rest has been devised which can be fitted to a Tudor-Thomas metal stand. A metal platform with four adjustable and removable legs, having a central hole to fit the top section of the stand rests on the shoulderlike portion of the stand, and can be rotated in any horizontal position. After placing the donor eye in the socket of the Tudor-Thomas stand the platform is lowered over it (figs. 1 and 2). 3050 Yonge Street.
