In an address before the society of microbiology in Dresden1 last May, Ehrlich drew back the curtain and gave several glimpses of the seething activity with which the new field of chemotherapy is being cultivated at the laboratories in Frankfort. Only one who is familiar with the difficulties and obstacles to be overcome at both the chemical and experimental ends of this work, can fully appreciate the enormous energy and tireless industry to which the abundant results that pour out from the Ehrlich institutions testify.
