Reference number: AP/7/3
Date: August 1808 - May 1809

Description
Burney writes on observations and experiments relating to the progress and acceleration of bodies that float in a stream, and which often descend faster than the stream itself, a phenomenon that Burney posits is due to perpendicular pressure. Preceded by a follow-up letter providing further clarifications on the paper.
Subject: Physics
Read to the Royal Society on 16 February and 18 May 1809.
