FOR FAMILIARIZING students with the biomicroscopic appearance of the normal and the abnormal aqueous humor a series of model eyes is of considerable value. The type of model which I have found satisfactory in postgraduate teaching, and which others may similarly find useful, has a convex glass "cornea," a rubber "iris" and a glass "lens," with an "anterior chamber" which can be filled with various artificial "aqueous humors."
The "eye" is constructed from a 5 cc. round bottom Pyrex microbeaker, a one hole no. 2 rubber stopper and a piece of 5 mm. glass rod. The rubber stopper is freed of talc and shortened to 13 mm. by removing a slice from the large end with a knife. The stopper is then pushed small end first as far as it will go into the microbeaker. A space approximating the anterior chamber in shape remains between the round bottom of the
