376 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. To the colonist it would prove useful by pointing out the saccharine strength of the juice at the mill, and to the sugar refiner it would be valuable by enabling him to determine the absolute strength of raw sugar.
175 페이지 - Craven, and can say that they are among the most interesting I have ever seen. You recollect that I said in my Report that with the increase in depth (in the greater depths) the number of individuals appeared to increase.

184 페이지 - To protect Building-stones from decay. — The stone surfaces of buildings, by being exposed to the action of the atmosphere, become liable to disintegration from various causes. Moisture is absorbed into their pores. The tendency of their particles to separate, in consequence of expansion and contraction, produced by alternation of temperature, is thus increased. Sulphurous acid is always present in the atmosphere of coal-burning cities, and cannot but corrode the calcareous and magnesian ingredients...

373 페이지 - ... for the purpose of quickening the process of germination. If all the seeds germinate, the seed obtains the highest value in the market. If only eighty germinate, the seed loses 20 per cent, in value. 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.
337 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.
