Hochgeehrter Herr College.
Besten Dank für die freundliche Zusendung Ihrer sehr interessanten Schrift, in welche ich eben gesehen habe, und welche ich noch ausführlicher zu studieren denke.
Die Aehnlichkeit der Eigenschaften Ihrer colloïden Lösungen mit denen der Enzyme ist in der That auffallend, wenigstens in mancher Hinsicht (Wasserstoffsuperoxyd), zu wünschen wäre die Entdeckung von diastatischen oder jeglichen Spaltungen durch Ihre colloïdalen Lösungen.
Ergebenst
B. Tollens

Dear Colleague,
Many thanks for kindly sending your extremely interesting treatise, which I have just seen and intend to study in further detail.
The resemblance of the properties of your colloidal solutions to those of enzymes is indeed striking, at least in some respects (hydrogen peroxide). It would be interesting to discover if your colloidal solutions induce diastatic or any other splits.
Sincerely,
B. Tollens
Göttingen, February 17, 1901
