At Tartu military hospital, one Dr. Meissner administered to military patients

In return for his exemplary work, he received permission to let students treat milder maladies and his name was put forward to the tsar for a decoration. Yet a number of letters emphasize that the doctor should not resort to “improvisation” in his medicine and that he should only use pharmacopoeia meant for Russian military use and the medicines stocked by the catalogues of the military pharmacies.
