found more complete in its illustration of the Palaeozoic forms of Bryozoa than 
any work yet published. 
Of the mechanical and artistic execution of the work I may speak in general 
commendation, and of some portions with unqualified praise. In regard to its 
scientific merit, I can only express the hope that students in Natural Science, 
and the enlightened educators of our State and Country, may find this volume a 
contribution worthy of their acceptance, and a source of material for that higher 
education and intelligence, which the people of New York so earnestly desire; 
and in this respect I hope that this volume may commend itself to your Excel¬ 
lency, as worthy of a place among the series of volumes already comprised in 
the Natural History of the State of New York. 
I have the honor to be, 
With great respect, 
Your obedient Servant, 
JAMES HALL,
