Mathematical treatment of fluid absorption by a vessel under combined osmotic and hydrostatic action shows that if the diluting effect of the absorbed fluid is not insignificant, a certain absolute as well as relative stability of fluid absorption will obtain, in spite of changes in the hydrostatic pressure relations. 5. The results indicate the existence of an aqueous drainage mechanism which tends to keep the rate of aqueous flow constant even at the expense of the stability of the
