Exceptional external communication (via Burroughs Wellcome & Co), 26 November, 1900, Dowson to Dr Archibold Smith, of Leeds, on the strength of horse serum: "with regard to the strength and activity of normal horse serum, I may tell you that no laboratory methods are at present known by which any activity it may possibly possess in the treatment of disease, can be estimated. Recent researches have made it plain that the serum of normal animals varies to a considerable degree in those constituents which influence its action upon foreign red blood corpuscles as well as upon those of its own species. Except, however, in so far as this work bears upon the theory of antitoxin formation it has not been brought into relation, so far as I know, with other treatments of disease."
