iferous fishes. The second, volume, which appeared in 1ST."), 
includes his detailed study of Dinichthys and the discussion 
of its relations to modern forms, a discussion which, whether 
it be accepted in all its conclusions or not, is a credit to sci- 
ence and a model in respect of the judicial method employed. 
Much additional matter upon the fishes of Ohio remained to 
be published in the third volume of palaeontology, which was 
not authorized by the Legislature. From this time, frequent 
brief announcements were made in the Transactions of the 
New York Academy of Sciences and elsewhere, until 1888, 
when his monograph of the Triassic fishes appeared, which 
contained descriptions and figures of twenty-eight species, fif- 
teen of them being new. This was followed quickly by a 
monograph of the Palaeozoic fishes of North America, also 
published by the United States geological survey; it contains 
descriptions of fifty new species, numerous new genera and 
careful revision of the studies upon Dinichthys and some other 
important forms, of which many new and much better specimens 
had been obtained. This was his last important publication. 
The one distinguishing characteristic of Dr. Newberry's 
method was conscientious study, which became more and more 
intensely characteristic as the years went by. This led to in- 
creasing caution, to careful comparison with the labors of 
fellow students everywhere and to frequent revision of his 
papers prior to public announcement of his results. No fear 
of losing priority could induce him to publish in haste; he 
never described a form as new until diligent search through 
all material within his reach had convinced him; his descrip- 
tions of field-work were prepared with equal care. This abun- 
dant caution made him exceedingly tenacious of his opinions 
when once formed and strong evidence was required to con- 
vince him of error. But when evidence was presented, it was 
weighed carefully and judiciously; no matter how unwelcome 
the verdict might he, it was accepted frankly and the error 
acknowledged unhesitatingly. The clearness and directness 
of his style were due to this painstaking study ; his statements 
were never open to the charge of obscurity. His method led 
him into broad investigation and his reading extended into 
many fields, so that he became a man with singularly well fur- 
nished intellect.
