1. A method of measuring the change in limb volume produced
by elevation of the venous pressure is described.
2. The experimental use of this method indicates that marked
individual variation occurs in the swelling resulting from an
elevation of the venous pressure to 60 mm.Hg., but that in the
same individual, the rate of swelling is virtually constant.
3. Evidence is adduced in support of the contention that tissue
tension plays a significant part in limiting oedema formation.
4. Changes in the rate of swelling in relation to posture are
discussed, and the failure of partial anoxaemia to affect the
rate of swelling is noted.
5. A brief survey of previous observations in the same field
is given. Certain criticisms of these observations and the
conclusions drawn therefrom are offered.
