Statistical data usually have a known practical value only when they are developed and generalized directly after the events, in the footsteps, so to speak, of the occurring facts. Therefore, I deeply apologize to the highly enlightened collection for the fact that I will allow myself to bother his attention with a little belated, brief, statistical remarks about the 4184 history of illness I have reviewed, taken by me for 1) from the archives of Kazan 1880 to 1892. In view of the fact that the history of the disease belongs to the number of clerical documents, then I understand that I must stipulate that these histories of the disease, which were in my order, have already served their legal term, have become the property of the archive and, likewise, no relation to the present to the functional staff of the hospital now, do not have.
