name of Passaic, in allusion to the river of that name, which 
flows over the entire system, it would have heen truthful and 
comparatively unobjectionable. Second. The name of Con- 
necticut or Connecticut River sandstone has precedence over 
Newark. My father is acknowledged to be the first of geol- 
ogists to have understood this terrane, and he identified it with 
the Trias or New Red sandstone of Europe. This was before 
the days of putting geographical names upon groups of strata 
in this country ; but he and others constantly used the expres- 
sion of Connecticut sandstone or its equivalent. The following 
gentlemen have made use of this expression in their writings 
before the time of Redfield's proposal in 1856, though none of 
them have formally proposed it as a geological term : E. Hitch- 
cock, Sir Charles Lyell, Dr. James Deane, Dr. S. L. Dana, Dr. 
Joseph Barrett, Dr. C. T. Jackson, Dr. John C. Warren, T. T. 
Bouve, and Prof. Jeffries Wyman. Third. In his lectures 
before the class of 1857 in Yale college Prof. J. D. Dana 
adopted the name of Newark for these sandstoiies, and presum- 
ably on other occasions. In his Manual of Geology published 
in 1861, and the later editions, he makes no allusion whatever 
to the name of Newark. These facts show that this gentleman, 
whose authority is second to none, saw fatal obje(;tions to the 
use of Redfield's name. Prof. 0. C. Marsh in presenting a table 
in Dana's Manual to show the succession of vertebrate life, for- 
mally uses the name of Connecticut River sandstone. This 
usage is not cited in support of a claim for priority. Fourth. 
While the New Jersey terrane possesses the distinguishing 
features of ^ the Trias, quite as well as the one in New England, 
it is fitting that the local geographical name should be derived 
from the latter, since that was the field of discovery of the 
fossil footmarks which has given the Connecticut valley an 
honored reputation throughout the scientific world. Mr. Russell 
has presented a long list of authorities who have written upon 
the Trias, and it is observable that only one of them has used 
the name of Newark — and that was the writer who proposed 
the use of the name. It seems hardly for the good of science 
to attempt to resuscitate a term that everyone has avoided 
using. Fifth. In the language proposing the new name for 
the terrane, the author finds it necessary to explain that these 
New Jersey sandstones arc thoroughly identified with those of
