Page 379 - Sketch of the Natural Provinces of the Animal World, and their relation to the different Types of Man, reaffirms the homogeneous characteristics and ethnic insulation of the American Indian on entirely novel and independent grounds.
Page 189 - Manual of Natural History for the Use of Travellers ; being a Description of the Families of the Animal and Vegetable Kingdoms, with Remarks on the Practical Study of Geology and Meteorology. To which are appended Directions for Collecting and Preserving.
Page 345 - ... subject, viz., the natural relations between the different types of man, and the animals and plants inhabiting the same regions. The sketch here presented is intended to supply this deficiency, as far as it is possible in a mere outline delineation...
Page 376 - 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.
Page 175 - 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. The greatest depth from which I had seen specimens was between 200 and 300 fathoms. There the sand contained perhaps 50 per ct.
Page 184 - 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...
Page 369 - M. Perrey of Dijon, would infer that earthquakes may possibly be the result of an action of attraction exercised by that body on the supposed fluid centre of our globe, somewhat similar to that which she exercises on the waters of the ocean...
Page 373 - ... 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.
Page 337 - 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.
