Burghölzli Zurich, 20. II. 1907.
I can leave Zurich at the beginning of March and I would like to come then to Vienna for a few days. As my main intention is to visit, I would like if possible to fix the date of my departure as it suits you best. It is unfortunately impossible for me to come later in March or April. I would be extremely grateful to warn me briefly.
Your very devoted
