Friend, I am grieved when I find a venator or hunter of your experience and observation, following the current of vulgar error. The animal you describe, is in truth a species of the bos ferus or bos sylvestris, as he has been happily called by the poets, but, though of close affinity it is altogether distinct, from the common Bubulus. Bison is the better word, and I would suggest the necessity of adopting it in the future, when you shall have occasion to allude to the species.
