Blagden, Charles

On February 21, 1809, Hatchett became a member of the famous Literary Club which had been founded in 1764 by Dr. Samuel Johnson and Sir Joshua Reynolds (51). As treasurer of the club, Hatchett prepared a brief historical account of it, which appears in Boswell s Life of Johnson (25). The club also included, among others, Edmund Burke, Oliver Goldsmith, David Garrick, Edward Gibbon, Adam Smith, Sir Joseph Banks, Sir Charles Blagden, Sir Humphry Davy, Dr. W. H. Wollaston, Sir Walter Scott, Sir Thomas Lawrence, and Dr. Thomas Young. 

The earliest, and I think so far unnoticed, record of an attempt by Watt to diagnose experimentally the chemical state of the steam inside a working engine is contained in an eyewitness report by Henry Cavendish. In early August 1785 Cavendish and his assistant Charles Blagden visited the Soho works of Boulton Watt at Birmingham. They were shown Watt s latest experiments on the steam engine, and Cavendish recorded the experience ... 

Cavendish s results were the same as Priestley s, but he did not publish or present his findings. Sometime before 1783, however, Cavendish did advise Priestley of his results. Priestley told Charles Blagden, secretary of the Royal Society in London, and Blagden in turn informed Antoine Lavoisier (1743-1794) in Lrance.

In 1783 Cavendish s assistant, Charles Blagden, visited Paris and told Lavoisier about Cavendish s work. Lavoisier rapidly repeated the experiments, and interpreted them in terms of his antiphlogistic theory by stating that water is a compound of inflammable air and oxygen (Chapter 5). 

Once again Lavoisier received a hint from a traveller from England. This time it was Charles Blagden, Cavendish s assistant, who visited Lavoisier in June 1783 and described Cavendish s quantitative experiments in which he had reacted two volumes of inflammable air with one of dephlogisticated air and found that in this...
