152 REPORT OF TnE AMERICAN COMMITTEE. 
the tlirce higher orders, leavhig the rest to the different countries. 
Witli certain exceptions he finds the suggestions admirable. 
Mr. Chas. E. Walcott takes numerous exceptions to parts of 
the report of the International Committees on Nomenclature, as 
mentioned above. 
Prof. Geo. H. Williams agrees unreservedly to the sugges- 
tions of the International Committees and the recommendations 
of the Congress. 
Prof. C. H. Hitchcock also is prepared to accept them. 
Prof. N. H. Winchell adopts the recommendations of Inter- 
national Committees and Congress with the qualification that he 
would have a series of zones or formations named from their 
dominant faunal characteristics, adopting some terms now in use, 
such as 1st fauna or primordial, etc., and while these expressed 
the chronological parallels throughout the v/orld he would name 
the rock-masses by other, say geographical terms, letting only the 
broadest cover large geographic areas, and in all cases allowing 
new geograjihic designations to arise in the separate countries for 
the rock masses where the contents of the specific horizons show 
such changes as to warrant new names. In short he would pre- 
fer a double set of names, one for the paleontological characters, 
which should be broad enough to extend throughout the world 
w'herever the included faunal dominant types extend, and one for 
rock formations : the latter to be flexible and applied locally. 
Mr. Thomas Macfarlane agrees in general with the sug- 
gestions, but incloses a list of preferences which have been pre- 
viously given. 
Prof. B. K. Emerson agrees in general with the recommen- 
dations of the Committee, and should be willing to accept them. 
Cart. C. E. Dutton believes that the geologists of the world 
are pretty well agreed that certain grand divisions of time may 
be adopted with some margin of uncertainty about their begin- 
nings and their terminations which are of world-wide significance 
and application, . . . but it does not seem to him that any lower 
order of time-division than the second (Cretaceous, Carboniferous, 
etc.), can have more than a local value. 
lie also incloses the list of amendments to the recommenda- 
tions of the International Committee on Nomenclature before 
noticed.
