The principal data are collected about the fall, April 19, 1808, and the distribution of the fragments of the Borgo San Donino, Italy, meteorite (long. 44° 52′ N.; lat. 11° 03′ E.). An Almost complete individual, weighing 447 g is described in some detail. Crust morphology, mineralogical composition, chemical composition and petrology were studied. Optical data were established by microscopic analysis of both thin and polished sections. The Borgo San Donino is an ordinary LL‐group chondrite, with a fundamentally hypochondritic texture and evident features of recrystallization and metamorphism. The presence of some anomalous chondrules is discussed
