Moreover, we should not have been able to make these necessary observations had we been devoid of the faculties (of sight) through which the elementary sensations of which the observations were the sum, were felt, nor should we have heen able to recognize the sensations so felt as those implied in the term tak, had we been ignorant of what sensations were implied by that term. Such terms as peculiarity, demon- strativfnrxs. au-kwardness, etc., are subject to the same rule.
