We have to inquire under the next head as to those regions coloured in the map as Upper Silurian, but w liich subsequent inves- tigations have relegated with some probability to older periods. I have said nothing above of the areas of Niagara, Lower Ilelder- berg, and Oriskany in the western counties, because 1 have not re- visited them since the publication of my edition of 1868, and have no further fiicts to present. Farther study of the fossils formerly col- lected has not materially modified the conclusions stated in Acadian (Jeology, pp. 4U8, 4'Jt*, and 571; but much remains to be done in this d
