ABSTRACT
Although it is a matter of common observation that ciliates and other Protozoa when starved become smaller in size, and often more slender in shape, very little quantitative work has been done on these changes. It is the purpose of this paper to deal in a quantitative way with the effects of the starvation of Glaucoma; in particular with the changes that result in size and shape. It is hoped that this study may throw some light on the mechanism by which the shape of ciliates is controlled.
