was a fit supplement to Brongniart and Desmarest's well known 

 work ; while his grand memoir on fossil Birds deserves to 

 rank with the classic volumes of Cuvier. Duvernoy, Filhol, 

 Hebert, Sauvage and others have also published interesting 

 results on fossil vertebrates. 



Van Beneden's researches on the fossil vertebrates of Bel- 

 gium have produced results of great value. Pictet, Riitimeyer, 

 and Wedersheim in Switzerland, Bianconi, Forsyth-Major, and 

 Sismonda in Italy, and ISTodot in Spain, have likewise published 

 important memoirs. The extinct vertebrates have been studied 

 in Germany by Von Meyer, Cams, Fraas, Giebel, Haeckel, 

 Haase, Hensel, Kayser, Kner, Ludwig, Peters, Portis, Maack, 

 Salenka, Zittel, and many others ; in Holland by Winkler, in 

 Denmark by Reinkardt; and in Russia by Brandt and 

 Kowalewsky. 



The fossil invertebrates have been investigated with care by 

 D'Archiac, D'Orbigny, Bayle, Fromentel, Oustalet, and others 

 in France ; Desor, Loriol and Roux in Switzerland ; Cappellini, 

 Massalongo, Michellotti, Meneghini, and Sismonda in Italy, 

 Barrande, Benecke, Beyrich, Dames, Dorn, Ehlers, Geinitz, 

 Giebel, Gumbel, Feistmantel, Hagen, von Hauer, von Heyden, 

 von Fritsch, Laube, Oppel, Quenstedt, Roemer, Schliiter, Suess, 

 Speyer, and Zittel in Germany. The fossil Plants have been 

 studied in these countries by Massalongo, Saporta, Zigno, 

 Fiedler, Goldenberg, Gehler, Heer, Goeppert, Ludwig, Schim- 

 per, Schenk, and many others. 



Among the recent researches in Palaeontology in other 

 regions may be mentioned those of Blanford, Feistmantel, Lyd- 

 ekker, and Stoliczka, in India ; ITaast and Hector in !New 

 Zealand, and Krefft and McCoy in Australia ; all of whom 

 have published valuable results. 



Of the progress of palaeontology in America, I have thus far 

 said nothing, and I need now say but little, as many of you are 

 doubtless familiar with its main features. During the first 

 and second periods in the history of palaeontology, as I have
