Mr. Hits on the Antilope Chickara. 505 
sent you, are individuals of the same species, although shades of 
difference do exist amongst them. I submit that the descriptions 
and drawings of the General's Antilope and M. Duvaucel's, by a 
singular coincidence, must ‘have both been made from imperfect 
specimens with regard to the first pair of horns, as an inspection 
of the two skulls now in the College Museum will make clearly 
manifest. 
There is a dicen of three inches between the height at the 
shoulder, as estimated by General Hardwicke, and that which I 
have given; but I followed the projection of the shoulder from 
the spine. The General probably placed his animal under an 
horizontal bar. 
How easily it may happen, that accounts drawn up with equal 
care and correctness, by different persons, of the same animal, 
and even of the same individual (and more particularly if it be of 
the deer kind), shall, owing to some unconsidered variation of 
circumstances, appear to arraign the fidelity of each other!
