Sir,
I herewith enclose copy of results of my last experiment with freezing machine,2 in the hope that it will be found suggestive of more accurate experiments.
I have removed my machine to No. 4, Red Lion Square;3 where I shall have it again in operation, in about a fortnight.
If you will intimate to me the time when you will be prepared to commence experiments, I shall endeavour to have everything in readiness.
I am | Sir | Your obed[ien]t serv[an]t | J. Harrison
