Frisch began the long series of works on the birds of Germany with which the literature of ornithology is enriched, by his Vorstellung der Vogel Teutschlands, which was only completed in 1763, and, its coloured plates proving very attractive, was again issued at Berlin in 1817.
Fischer's Versuch einer Naturgeschichte von Livland appeared at Konigsberg, next year Beseke brought out at Mitau his Beytrag zur Naturgeschichte der Vogel Kurlands, and in 1794 Siemssen's Handbuch of the birds of Mecklenburg was published at Rostock.
In 1832 Kittlitz began to publish some Kup- fertafeln zur Naturgeschichte der Vogel, in which many new species are figured; but the work came to an end with its thirty-sixth plate in the following year.
In 1845 Reichenbach commenced with his Praktische Naturgeschichte der Vogel the extraordinary series of illustrated publications which, under titles far too numerous here to repeat, ended in or about 1855, and are commonly known collectively as his Vollsteindigste Naturgeschichte der Vogel.
In the year last mentioned the greater part of these was separately issued under the title of Beitrrige zur Kenntniss der Naturgeschichte der Vogel.
