Letter from [William Hallowes] Miller, to Professor [Samuel Hunter] Christie, The Royal Society Discusses Dr. Waller's paper on the vesicular theory of cloud formation, expressing surprise that anyone would bother to refute this well-established idea and mention that various authorities, including meteorologists and writers, support the theory. Highlights a few individuals who hesitated to accept it. Acknowledges that the Royal Society cannot investigate every error, but believes that in this case, given the reputable authorities who were misled by [Horace Bénédict] de Saussure, it would be valuable to consider Dr. Waller's observations. Recommends Dr. Waller compile a list of vesicular theory advocates for his paper's publication. c.1847
