Apologizes for sending a letter of introduction for someone recommended to JH, without first getting to know the third party.
Asks for copies of some of MF's writings to complete JH's set.
Comments on MF's experimental results when an electromagnetic field affects polarized light.
Has just seen mention of MF's latest experiments showing the connection of light and magnetism. Comments on these. Proves some of his own theories to be correct.
Sends details of an experiment he would like MF to carry out. Cannot do it himself as he has no suitable glass.
Has opened the sealed paper MF sent, and JH is now returning it.
Thanks MF for sending a 'healing liquid.'
On the periodicity of sun spots.
More on lacunae in JH's set of MF's writings [see JH's 1838-10-3].
A furnace for glass making is under construction at the Royal Institution.
Cites six journal articles relating to chemical separation of titanium and iron. Sent report to Henry Kater.
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.
Gratitude for receipt of JH's Cape Results. Congratulates Margaret Brodie Herschel for her part in it.
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.
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 found some errors in the printing of his paper. Sorry to hear that JH has been indisposed, but believes he is progressing.
