In the department of natural science are to be mentioned, Presl, count Berchtold, Strnad, Sedlaczek, Wydra, Smetana, etc. Others, Bohemians by birth, have written in German, e.g. Haenke, Sieber, etc. etc. Count Buquoy also is of Bohemian origin.--Writers of merit on moral and religious subjects are, Rautenkranz, Zahradnik, Parizek, and others. The Slovak Bartholomaeides, a distinguished scholar, has written several useful works on various topics.--Periodicals full of learned researches and variety of interest were edited, _Dobraslaw_ by Hromadko and Ziegler, _Krok_ by Presl, etc. Modern journals of a more general tendency are _Wlastimil_ (the Patriot), _Dennica_, etc. Among the highest nobility the national language found powerful patrons; and in the establishment of a national Museum, a Bohemian Academy of Sciences, and similar patriotic institutions, the national literature received great encouragement. One of the principal objects of this institution was to publish old works and to patronize new ones. Its first publication was an old treatise on Bohemian law.[47] The names of the counts K. Sternberg and Kolowrath-Liebsteinsky must be mentioned here; to which, in our days, may be added those of the counts J.M. and Leo Thun. The leading poet of the present day in the Bohemian language is J. Kollar, born 1793 at Thurocz in Hungary. In 1821 he published a volume of poems; and some years later a larger beautiful poem in two cantos, called _Slawy dzery_, the Daughter of Glory, by which he meant _Slavina_, or the Slavic nations personified; for _Slava_ means glory. With talents of the first order, and at the same time purely national, he imitates Petrarch in some measure; making his nation his Laura, praising her beauty, and prophesying her ultimate triumph.[48]
