From Ohio History Central
The buffaloes are dark brown in color, covered with long hair, or rather soft down mixed with hair. Their legs are short, the body is heavy. They have a hunch upon their backs, just above the shoulders. This diminishes towards the rear, hence, they appear much shorter from the back than from the front. They have a thick head and a long beard depends from the chin. Altogether, they present a terrible appearance. Their horns are short, but thick and quite black.
