are found notes ''Ou the Classification of Sporangites,^^ p. 84 ; "On the 

 Nature and Affinities of FtUophyton,''^ p. 86 ; " On Tree Ferns of tbe Erian 

 Period," p. 90 ; " On Elian Trees of tbe Genus Ikidoxt/lon, Un<,'er," }>. 06 ; 

 "On Scottish Devonian Plants of Hugh Miller and others," p. 1)8; "On 

 the Geological Relations of some Plant-bearing Beds of Eastern Canada," 

 p. 103; "On the Relations of the so-called 'Ursa Stage' of Bear Island 

 with the Paheozoic Flora of North America." At the end of chapter 

 IV twenty-seven pages of fine print are devoted to a note "On Charac- 

 ters and Classification of Paheozoic Plants." In an appendix there are 

 eight pages giving ."A Comparative View of the successive Palaeozoic 

 Floras of Northeastern America and Great Britain," and a few pages on 

 " Heer's latest results in the Greenland Flora." The volume is particu- 

 larly complete in its account of the plants of the Devonian of North 

 America, in which field the author is the chief authority. 



Leo Lesquereux (148) has prepared for the annual re.port of the Geo- 

 logical Survey of Pennsylvania a short treatise on the " Characters and 

 Distribution of Paheozoic Plants," in which the plants of the Carbon- 

 iferous system are chiefly discussed. The author also considers the evi- 

 dences ottered by plant remains of the physical conditions under which 

 the deposits »were formed, and the relations the several geographical 

 tracts -of North America in which coal measures appear bore to each 

 other during the Carboniferous age.
