SOME RELATIONS ESTABLISHED BY THE FOOD OF BIRDS IN THE LIFE OF THE BALATON LAKE I finished, I believe, the first chapter of my researcdes in the Balaton-area. These results fixed partly the conditions and changes between 1914-1975 of the bird-life with regard to the earlier observations, partly I made an attempt to give a qualitative and possibly also a quantitative picture on the seasonal changes of the bird-life of the Balaton-lake. The results give a basis to the research of the connections in the life of the Lake, which was originally the goal of ENTZ, who suggested also ornithological observations, as the birds have an important role on the life of the Balaton. In my newer study I should make an initial step in this direction and this is the bromatology of Balaton-birds. The concept of bromatology was suggested by HEIM DE BALSAC /1928/ and in the studies of VASVARI /1929-1954/ this term was consewuently used, but it is to be regretted that this term has not been generally accepted by the modern ornitology. The principal task of bromatology was to change the economical aspect prevaling in the last years of the nineteenth
