9 June 1862
This letter will be presented to you by Dr. David Walker who is proceeding to B. Columbia.
Dr. Walker, who has been recommended to me by Sir J. Emerson Tennent, was Surgeon and Naturalist on board the "Fox" during Sir E. McClintock's exploring expedition in search of the remains of Sir John Franklin. He is now going out to B. Columbia to prosecute the study of Natural History and to make collections in the Colony. I do not doubt that you will be happy to afford him any attention or assistance in your power.
I have etc.
