When, a few months ago, your Association honoured me with its invitation, I undertook the task of presenting to you the results of the first 100 cases treated in the Clinic in Vienna. I intended to draw from the individual reactions and the effect of the therapy some conclusions as to its justification. I could also have brought forward conclusions drawn from the records of cases whose treatment has been terminated for a long time and who have remained under continuous observation. These results would have been of some value inasmuch as these would have referred to the cases which I myself treated individually, and in which treatment had been individualized by employing various types of shock.
