The principal part of the volume is a toa toclogiens descrip- 
tion of the chalk formation of Texas, with an enumeration and de- 
scription of its organic remains, sores occupy eighty-eight pages of the 
volume. These are followed by descriptions of Paleozoic fossils, and 
of three species of fossil wood from the tertiary. 
The cretaceous fossils figured occupy ten quarto plates, and number 
one hundred and twenty- -four. Of these one bundred and one are new 
or yet undetermined species, and twenty-three are identical with spec 
previously known. ‘These are senotiadty illustrated, The Pa iescnitl 
fossils number ten species, of which eight are new. hese are chiefly 
of the carboniferous period, and we recognize them as forms which 
prevail farther to the north and west in the same formation. ‘The three 
species of fossil wood from the tertiary, described by Pad ae are Silli- 
mania Texana, Roemeria Americana, and Thuyoxylon Americanum. 
The fossils here described and figured, had been already indicated 
_in Dr. Roemer’s previous work on Texas. 
m4 present work offers a very valuable accession to our knowledge

know of it, we have but a foreshadowing of what is yet in store for us 
when this formation, which extends from the Tropic of Cancer to the
