Bison, or the Canadian Elk to that of the Old World. Its occurrence in America is not 
more startling than that of the Musk-sheep in the South of France. But it extends the 
ancient range of the Cave Lion eastwards through Russia and the vast steppes of 
Northern Asia, across Bhering’s Straits into the great treeless barren grounds of North 
America, and thence southwards into the zone of the woods, and over the great prairies 
of the Bison, down to the almost tropical region of the Gulf of Mexico. Subsequent 
investigation will, doubtless, prove its former existence in the intermediate area just as 
in the parallel case of the Mammoth. What we know of the living Carnivores, such as 
the Wolf, Fox, and ‘Tiger, would naturally lead us to expect those found in a fossil state 
to have a far wider range than any of the Herbivora.'
