384 페이지 - Peligot subsequently analyzed it, and found 20.9 per cent, of sugar. Biot, therefore, suggests that those who make, as well as those who refine sugar, might resort to this test as a means of determining the amount of sugar in different juices or solutions.

This process ordinarily occupies from twelve to fifteen days ; but Mr. Lawson found that by using blue glass they are enabled to determine the value of seed in two or three days : and this is a matter of such commercial importance to them that it is quite equal to a gift of £500 a year.
345 페이지 - I would add, it makes little difference whether the mental inferiority of the Negro, the Samoiyede, or the Indian, is natural or acquired ; for, if they ever possessed equal intelligence with the Caucasian, they have lost it ; and if they never had it, they had nothing to lose. One party would arraign Providence for creating them originally different, another for placing them in circumstances by which they inevitably became so. Let us search out the truth, and reconcile it afterwards.
