[F. C. NAPP andJ. G. MENDEL a contribution to the prehistory ofMENDEL's experiments].

On the centenary of the death ofF. C. NAPP (22. 7. 1867), abbot of the St. Thomas-monastery of Old-Brünn, who admittedJ. G. MENDEL in his convent, enabled him to study natural science and to carry out his experiments, and on the centenary of the election ofMENDEL to succeedNAPP as abbot (31. 3. 1868), we take note of the relationship between these two men as it concerns the discoveries ofMENDEL. Following a short biography ofNAPP we appreciate his service to agriculture and its basic sciences. We find a close connection between the scientific work ofMENDEL andNAPP in meteorology and bee keeping.
