-1922.

The Academy issued three early reports entitled Report of the transactions, 1824-1827/1828 after which apparently no more were printed until 1841, when the series of Proceedings (including reports) was begun. The reports continued to be published in the Proceedings, with offprints of at least some of them, until 1919; reports from 1920-1922 were issued in separate form only, containing, in addition to the regular reports, special reports by members of the scientific staff based on explorations conducted in the interest of the Academy.
