In a previous paper1 it was suggested that in addition to the blood aqueous barrier, there must be a vitreous barrier with selective properties and an independent function, separating the vitreous humor from other parts of the eye. The vitreous body may, therefore, be regarded as a separate unit with its own chemical and osmotic climate.

If this is true, the volume of the vitreous body may increase or decrease according to variations in the chemistry and osmosis of the eye. Since alterations in the size of the vitreous are likely to change the position of the ocular diaphragm, experiments have been carried out to find out whether this diaphragm moves or not. Had it been revealed that the diaphragm remains immobile, changes in the size of the vitreous body would not be likely to occur. Granting, however, that the diaphragm does alter its position there may be several
