 publish, in 1820, his '^ Essay towards a Geognostic-botanical 

 Representation of the Flora of the Pre-esisting World." In this 

 work he not only gave a great number of very beautiful colored 

 engravings of vegetable fossils, but also attempted a systematic 



classification of them.

 which offered themselves, could only be solved by combined la- 

 bors on a common plan ; and after mentioning the various Euro- 

 pean Societies to which he looked for assistance (among which he 

 includes this Society,) he adds, ^'Bohemia and the hereditary 

 states of the Austrian empire, I am ready, with some friends of 

 science, to make the subject of continued investigation." The 

 specimens of which he published representations, with many

 from Brzezina to the capital. This was afterwards done ; and in 

 this and other ways he was one of the principal founders of the 

 Museum at Prague. He also gave notice, that while the collec- 

 tion continued in his own residence, it was open to the inspection 

 of every lover of science, even in the absence of the Count himself. 

 The publication of Sternberg's Flora der Vonvelt went on till 

 1825, after which it was discontinued till 1838, when two parts 

 appeared, terminating the work. In this last pubUcationhe states

 that though thus no longer able to pursue the path which he has 

 trodden for twenty years, he shall not fail to render to the science, 

 of which he was one of the founders, any service which may be 

 in his power. This publication was the crowning labor of his life, 

 for he did not long survive it : he retained, liowever, to the last 

 the elasticity and activity of his mind. He died very suddenly 

 at his covmtry seat already mentioned, on the 20th of December, 

 1838, being carried off by apoplexy in his 78th year.
