Carpenter hopes Wilson can 'undertake the whole set of lectures in the week beginning Feb 13', or at least 'part of them'. He has 'arranged for Dr. J. Geikie for the week beginning Jan 30th' and shall ask him to take 'any days in that week [i.e. beginning Feb 13] which you may not be able to give us'. He asks Wilson to contact Geikie direct on this point. Wilson was a Gilchrist Trust lecturer and lecturer on physiology and health.
