in the series of magnificent works which we are promised in the 
present report. We make a few extracts regarding the discoveries - 
made by the survey. The fossil invertebrates are to be worked up 
by Profs. Hall and Worthen, many novelties having been found. 
“The interesting collection of Amphibian remains, which in- 
cludes more than a dozen species, obtained by myself some years 
ago from the coal rocks of Ohio, has been placed in the hands of 
Prof. E. D. Cope, of Philadelphia. He has described them and 
caused them to be carefully drawn. They supply material for six 
or more plates, which will add much to the interest of our final 
report 
port. 
The fossil fishes and fossil plants found in the State have been 
described by myself. They have been drawn by Mr. T. Y.G 
ner and Mr. G. K. Gilbert in a style that has not been surpassed 
lar character done by the best European draughtsmen. The il 
are not exceeded in scientific interest by any that ha i 
described by palæontologists. The fossil fishes comprise D 
genera and species, some of which are more remarkable pte | 
size, their formidable armament or peculiarities of Liste ving 
any of those which formed the themes of Hugh Miller's irs 
descriptions. These have, for the most part, been ound inter-
