Unpublished paper, 'The influence of the force of gravity on the circulation' by Leonard Hill

Description

Hill presents his experimental observations on the influence of the force of gravity on the circulation. He writes: 'I have found that on attempting [...] to fill the circulatory system of the dead animal with salt solution, the arterial part of the system does not remain filled, for the salt solution rapidly leaks into the splanchnic venous area. By alternately placing the animal with feet down or with feet up, a pumping action is produced which gradually forces the salt solution out of the arterial system into the venous side, where it remains. The indifferent point, therefore, cannot be found on the dead body.'
