A furnace for glass making is under construction at the Royal Institution.
Indicates the best way for the glass subcommittee [of the R.S.L.] to deal with the results of glass experiments at the Royal Institution [see MF's 1827-11-3].
Informs MF that JH has been called to serve on a grand jury and so may have to miss some glass subcommittee meetings. [This note enclosed the letter written by JH on 1827-11-6.]
Describes the tests JH made on a small glass prism of not very high quality, which JH has left at the Royal Institution.
Sends MF some older samples of imperfect glass. Talks about the way in which different kinds of glass should be layered in lenses.
Sends a note with a letter from W. H. Wollaston to JH, dealing with glass making experiments.
Chemical constitution of meteorites. JH suspects lead-iron alloy. Believes this has not been proposed before. Send specimen for JH's analysis.
Rearranges a meeting of [the R. S. L.'s Glass Committee] to take place at the Pellat and Green's Glass House in Holland St.
As MF will be unable to attend the next meeting of the Glass Committee, he sends JH the analysis of the glass produced in one experiment, emphasizing its consistency and high quality.
Sends JH the results of the analyses of several specimens of experimental glass.
Comments on the intent of remarks appended to a paper of MF's.
Suggests change in composition of a pot to be made by [Apsley] Pellatt for an experiment.
Hopes to meet JH in London, and to finish building for R.S.L. soon. Discusses various prisms for experiments. Mentions 'neat' process for drawing uranium from iron.
Proposes an adjustment in the proportions of the ingredients in the next glass-making experiment.
Discusses origin and reactions of enclosed borate of lead. Postscripts on parallel strata in glass.
Thanks for the copy of his paper and errata. Received a packet of specimens of glass, which he presumes came from MF. Regarding the specific gravity of some of the specimens. Comments on further experiments to be made.
Regrets that Richard Taylor has printed his own paper in the P.M. before it appeared in the R.S.P.T. Explains the reason. Is examining various pieces of glass and will forward the results.
Agrees with JH regarding the glass. Suggests that a meeting would facilitate results. Suggests that the glass maker should make several pots for the experiments.
Sending a paper for the R.S.L. Humphry Davy does not approve entirely of his arguments. Would be pleased if JH would glance over it and then inform Davy that he has it.
Has read his paper on vaporization with much interest and can see no objections to its arguments. Comments on some of the details.
