“ In the first place, I would observe that the presence of only thirty-four ribs in an equine race, whether ancient or modern, would not be by any means abnormal, or contrary to the laws of Nature; for it is fully agreed now that the number of these bones is far from being constant in our present horses. Indeed, Chauveau remarks as follows on the number of ribs in the horse: ‘We reckon for each lateral half of the thorax eighteen ribs. Not unfrequently we find nineteen, with an equal number of dorsal vertebræ in well-formed horses; but, then, most usually there are only five lumbar vertebræ.’ ”
