Dear Prof. R. Houseman,
I am greatly honoured by the letter of J. A. Phillips, of September 25th inviting me to participate in the 14th International Conference on New Applications of Biochemical Research.
However, I am afraid I shall have to decline your kind invitation, for I see no possibility of attending the Conference, owing to a prior engagement for that time.
