Samuel Blatchford, Harrison v. Merritt — Opinion of the Court
“ We are of opinion that the article was not free, nor liable to a duty of 35 per cent. as a manufacture of bones, but that, being bone-black, it was liable, as 'black of bone,' to the duty imposed on it; and that it was proper to direct a verdict for the defendant.Objection was made to the admission of evidence to show the difference in value between bone-black and crude bone; and that between bone-black and white calcined bone-ash; and that between bone-black before its use by sugar refiners and after it was spent. We see no good objection to the evidence. ”
