right externus (and less so of the two obliques) and of the left internus (and less so of the superior and inferior recti). In investigating the ocular muscles, the simpler the technique the more accurate the findings. For the median and lateral recti we start with the eyes in the primary position; for the left obliques we start with the eyes right, for the right obliques with the eyes left; and for the superior and inferior recti we start with the eyes toward the side of the eye under question. From the last two cardinal positions (that is, eyes right and eyes left) the eyes are directed upward or downward, respec­ tively, to investigate the elevators or de­ pressors. May I therefore respectfully suggest that we change the phrase "down and right" to "right and down"; "down and left" to "left and down" ; "up and right" to "right and up"; "up and left" to "left and up." This is not the first time this subject has been brought to our attention ; but it is worth repeating because of its extreme simplicity. 122 South Michigan Avenue.

The point of incision of the sclera is selected, and the bulbar conjunctiva is incised, exposing the sclera. The sclera is incised through approximately two thirds of its thickness in a similar manner as for cyclodialysis. A piece of 6-0 silk on an atraumatic needle is placed through the two lips of the wound and the threads drawn up in a loop from the bottom of the wound (diagram). After completion of the incision, these can be used as trac­

tion sutures to make the wound gape for the insertion of instruments and the re­ moval of the foreign body. After removal of the foreign body the ends of the sutures

are drawn together and tied, giving a firm closure and, if cut short, can be left buried. 812 Maison Blanche Building.

Technical advances in one field of sci­ ence frequently lead to improvements in the methods used in other fields. Such has been and remains the case as regards ma­ terials for making impressions of the mouth prior to fitting artificial dentures, and in the making of impressions of the anterior segment of the eye for molded contact lenses. The various impression materials used in the making of molded contact lenses in-
