From Trenham Reeks 14 March 1845
Museum of Economic Geology
14th. March 1845.
Dear Sir,
I had some conversation with Dr. Kane of Dublin,1 last Evening upon the decomposition of Carbonate of Lime and Common Salt2 and he mentioned that M D’Arcet3 had found upon mixing these two substances after a certain time an efflorescence of Carbonate of Soda made its appearance. Upon this ground a manufactory for Carbonate of Soda was established4 which very soon failed from the small quantities produced. So that it appears there must be some amount of action take place upon these bodies en masse.
Mr Phillips5 desires me to say his time is so very much occupied he has hardly had time to write but that he finds the rock to contain only traces of Sulphate of Lime.
I am, Dear Sir | Your’s sincerely | Trenham Reeks C Darwin Esqre. | &c &c &c
