Discovered an agent that renders his paper tough and waterproof. Sends sample for JH's inspection. Treated paper is highly explosive and can discharge a gun.
Received JH's check for £300 for Harris family. Measurements of Gamma Virginis made by W. R. Dawes under GB's direction. Will send future observations to JH.
Will be showing some experiments in the laboratory next Monday to G. B. Airy, François Marcet, and a few others; JH would be welcome.
William Mann returns to England still in poor health. Expresses concern over running of Edinburgh Observatory by C. P. Symth. Regrets poor data from Cape Observatory on Comet of 1843. Observed Comet Gambert. Situation with Caffres hostile.
