The favorable conditions of his family, his teachers and environment (Bo- logna) helped to produce good results in his scientific education. He graduated at Reggio in 1634 in accordance with the edict of his sovereign, the Duke of Modena, who would not permit his subjects to graduate outside the jurisdiction of his dominions. He soon returned to Bo- logna to resume his studies in medicine and to perfect himself in practical medicine in hospitals, where he had Salani as a teacher. The rivalry be- tween Sbaraglia and Malpighi which also generally involved the students, did not affect Vallisneri.

The editor Albrizzi did not always publish the exact ideas of Vallisneri in the Galleria, but altered them to such an extent as to provoke the keenest resentment in the author and finally his work ceased to appear in the famous Galleria. But nevertheless Vallisneri’s renown spread among men of science, and the University of Padua offered the young doctor the chair of Practical Medicine.
