    i Dialysis : a stage in the purification of sera Four years previously, he and Dr. Pope had prepared toxoid- antitoxin floccules (T.A.F.) for human use. Thus the two prophy- lactics which have made possible the success of the present Diphtheria Immunisation scheme in Great Britain both came from The Wellcome Research Laboratories. Nor were these the only contributions of the Laboratories to the prevention and treatment of this disease. Dr. O'Brien, a pioneer advocate of active immunisa- tion against diphtheria, was the first person in Great Britain to carry out Schick testing, his observations being greatly extended later by Dr. Parish and Dr. C. C. Okell. As the Laboratories had been engaged in the preparation of diphtheria antitoxin, it is not surprising that the efficient methods of purification should have been evolved there. During 1920 and 1921, Dr. Hartley developed a medium for the production of the toxin which has found world-wide use. He was also a pioneer in low temperature drying of sera and other protein solutions. In 1938-39, Dr. Pope introduced a new method of purifying the antitoxin by
