Prof. Salisbury has doubtless studied them in a more distant field; 
and it has been very encouraging to the present writer as a layman 
to find his views so often confirmed by more learned authorities. It 
is only by comparing views and observations made in widely sepa- 
rated sections of the country, that correct solutions of the many 
perplexing problems can be arrived at. 
I write in no captious spirit. My only desire is to aid in reaching 
the truth and that the cause of science may be somewhat advanced.

Bison latifrons and Bos Arizonica. In my recent paper upon 
the remains of a Species of Bos in the Quaternary of Arizona reference 
should have been made to the important monograph by Dr. Allen upon 
the living and extinct American Bisons.* The reference is especially 
important inasmuch as Dr. Allen describes two large and perfect horn- 
cores from Adams county, Ohio, presented by Dr. O. D. Norton to the 
museum of the Nat. Hist. Soc. of Cincinnati, which cores, in size, shape 
and general proportions closely resemble the cores from Arizona. Ex- 
cellent figures are given from a photograph about one-fifth size. The fol- 
lowing are the dimensions, or measurements, of these cores : 
Measurements of the Adams Co. Ohio Horn Cores. 
Length of the Upper or concave side :-i2 inches or S13 mm. 
Lengtli of tlie lower or convex side 34 inches or i>53 mm. 
Cirrmmference at the base • 20 inches or 510 mm. 
« ircumference 10 inches from the base 16 inches or 407 mm. 
Circumference 14 inches from the base UVs inches or 368 mm. 
Circumference 24 inches from the base 9'A inches or 24') mm.

The width of the skull between the horn cores is estimated to be i6 
inches or 407 mm. 
Allen observes that "the remains of the larger extinct bisons so far as 
yet known are not only few in number but come from not very widely 
separated localities, and that the great deposits of bones found at the 
Kentucky salt licks, especially that of Big Bone Lick, have yielded, thus 
far, no remains that have been identified as belonging to this gigantic 
representation of the ox tribe although containing the remains of Masto- 
don, Elephant, Megalonyx and Mylodon, together with those of the fos- 
sil horse, the great extinct musk-ox, the lesser extinct bison, the extinct 
peccary, the caribou and the moose." 
The remains from Ohio, Nebraska and Arizona indicate a much wider 
distribution of the gigantic animal than was known at the time of publi- 
cation of Allen's monograph. In the map indicating the gecjgraphiral 
range of the bison the area does not extend as far as the Arizona line. 
While Europeans generally have referred the American remains of 
the extinct bos and bison to Bison priscus of the old world it was the 
opinion of Dr. Allen, and it is apparently well sustained by the later dis- 
coveries, that the remains indicate an animal so immensely superior in
