It is with the greatest joy that I go to meet the proposal of prof. Aristovsky to write an article on the treatment of amoebic dysentery for the anniversary issue in honor of my highly esteemed friend, Professor Gruzdev. I remember with gratitude during these hours that comradely-friendly welcome which I, together with the expedition of the German Red Cross, found in 1921-22. it was in the circle of persons of the Medical Faculty of Kazan University, grouped around prof. Gruzdev.
