The materials and the conclusions presented in this paper are the partial results of studies of the Devonian of Western New York, which have been of several years duration. Since the summer of 1877 much attention has been given to the finer subdivision of the Devonian on strictly paleontological evidence, the rich development of Devonian faunas within Ontario County, and in its vicinity, having af

It has therefore been deemed proper, in this introduction to the several tabular and systematic statements which will make up the bulk of the volume and bear chiefly upon the geological aspect of the subject, to consider certain of the more important b

Through the following tables there are presented, in accessible form, such portions of the more important numerical results of this Survey, from the year 1873 to 1879, inclusive, as it has been found neeessar, to compute pari passu with the plottings made from the field notes, together with such additional determinations as may have been required in the construction of the final atlas sheets.
