420 SKETCH OF PALEOBOTANY. 



which, as a thorough botanist, he was perfectly familiar. He nowhere 

 refers to any treatise on the nervation of leaves, and as those of Bianconi 

 {svpra, p. 380, note 27) are not included in his "Literatura nostri sevi," 

 it is probably safe to infer that he was unacquainted with them. In 

 drawing his figures he adopted the old method of figuring the stone 

 as well as all the defects in the impression, which while requiring an 

 immense amount of unprofitable labor, rendered the result much less 

 clear and less valuable than it would have been had these features been 

 •omitted. The fifty plates, however, by which this work is illustrated 

 constitute an enduring monument to the skill, energy, and industry of 

 their author. 



Pomel's paper on the Jurassic flora of France,"'' which appeared in the 

 oflftcial report of the association of German naturalists and physicians 

 for 1847, though unaccompanied by illustrations, proved a highly im- 

 portant contribution and gave a new impetus to the study of that 

 formation from the vegetable side. 



Some dozen or more other memoirs of greater or less import were 

 contributed during 1847 by Binney,^" Pr. Braun,^!^ Bunbury,^^'' Gop- 

 pert,^^' Lesquereux,^^^ Eouillier,^^^ and others, none of which can be 

 specially considered here. 



About thirty papers and books, small and great, relating to fossil 

 plants appeared in 1848, none of which, however, can be ranked as great 

 works, unless it be Bronn's Index Palteontologicus,*^ which merely 

 includes the plants with all other fossils in one alphabetical arrange- 

 ment. The number, however, of what may be classed as second-rate 

 productions was quite large. Among these we may count CTnger's 

 " Flora von Parschlug,"^'^ Berger's thesis "De fructibus et seminibus
