Thomas Andrews to Faraday   11 April 1844

Belfast 11th April 1844

My dear Sir

From a note of Graham's I find that your exertions on my behalf have been attended with success and that my paper¹ has been ordered for publication. For the kind manner in which you have acted towards me on this occasion I can never be sufficiently grateful.

I was very much interested by your observations on the constitution of matter². The argument, although so simple, appears to be unanswerable. I have often been surprised that so many views which never ought to have been received as more than plausible conjectures should gradually be adopted as demonstrated facts.

I have been very actively engaged in extending my inquiries on the subject of heat. After encountering many difficulties I have succeeded in rendering my method of working very precise. I have some excellent thermometers of great sensibility and accuracy, and I have devised a method by which I can at any time determine the calibre of any part of the tube and thus render the results strictly comparable with one another.

I hope soon to be able to communicate to you some new experiments which will extend & confirm the results already obtained.

I sincerely trust you continue to enjoy good health. I am unwilling to importune you with invitations, but if you feel at any time disposed to visit this part of the country you shall receive the national welcome from

Yours truly obliged | (signed) Thomas Andrews

Michael Faraday Esq | &c &c &c
