Has found some errors in the printing of his paper. Sorry to hear that JH has been indisposed, but believes he is progressing.
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.
Sends JH the results of the analyses of several specimens of experimental glass.
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.
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.
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.
Was grateful for JH's letter and detailed notes. Hopes he will attach a copy to the paper when he communicates it to the R.S.L.
Has just received his letter. Has had no opportunity of examining the iron. Several years ago he made some experiments on the alloys of lead and cast iron, but does not remember the results. Is surprised that no new metal has been found in meteorites.
Has been trying to see him, unsuccessfully, about the affairs of the Optical Glass Committee. Hopes that JH will not resign from the Committee now that he is no longer Secretary at the R.S.L.
A furnace for glass making is under construction at the Royal Institution.
The furnace is breaking away at the top, and he encloses Joshua Ramsay's estimate for its repair. Thinks the present a suitable time for the repairs. Would JH speak to the Council?
Has made a piece of glass 5" square, which George Dollond reports is good. Proposes making a furnace at the Royal Institution. Does JH have any objections?
Discusses origin and reactions of enclosed borate of lead. Postscripts on parallel strata in glass.
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.
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.
Has read his paper on vaporization with much interest and can see no objections to its arguments. Comments on some of the details.
[More detailed version of JH's 1826-5-26]. Has mentioned it to Humphry Davy.
Comments on the intent of remarks appended to a paper of MF's.
Chemical constitution of meteorites. JH suspects lead-iron alloy. Believes this has not been proposed before. Send specimen for JH's analysis.
Proposes an adjustment in the proportions of the ingredients in the next glass-making experiment.
