Page 342 - Boussingault made his experiments in a better form, upon leaves only, avoiding all complication of the action of the roots or other parts of the plant. His results are : 1. That leaves exposed to sunshine in pure carbonic acid do not decompose this gas at all, or only with extreme slowness. 2. But in a mixture with atmospheric air, they decompose carbonic acid rapidly. The oxygen of the atmospheric air, however, appears to play no part. 3. Leaves decompose carbonic acid in sunshine as readily when...
Page 142 - Louisiana, &c., the country is influenced at certain periods of the year by the northeast trade winds, and north of the same belt by the polar winds, which, on account of the rotation of the earth, tend to take a direction toward the west. It must be recollected that the westerly direction of...
Page 260 - It will be seen that the largest part of the land under the plough was occupied by crops of wheat, barley, and oats. Wheat was the customary food of the people of this country from the earliest times. Even if the evidence were not abundant on this point, the breadth sown annually would be conclusive proof. Barley was sometimes mixed with wheat in the allowances made to farm servants, but its chief use was in the manufacture of beer, which seems to have been continually brewed in small quantities,...
Page 343 - ... irremediably destroys the life of the cells of a leaf, vegetable life in this state being far less tenacious than that of some of the lower animals (Tardigrades, Notipes, &c.), which bear wonderful desiccation. The third instalment of the investigation is given in Nos. 16 and 17 of the same volume (Oct. 16 and 23, 1865). It appears that detached leaves, kept in shade for many days, with the cut end of the petiole in water to prevent desiccation, preserve the power of decomposing carbonic acid...
Page 343 - ... desiccation, preserve the power of decomposing carbonic acid whenever brought into sunshine. But for this they must be kept in an atmosphere containing a supply of oxygen ; without this they soon die, as Boussingault thinks, from asphyxia. The oxygen in darkness is slowly transformed into carbonic acid, through an operation which is presumed to go on continually, whether in light or darkness, and to answer to respiration. Of course a healthy and active leaf decomposes far more carbonic acid in...
Page 94 - In conclusion, we consider that twenty rings (arthromeres), as a rule, compose the bodies of insects, of which seven are contained in the head, three in the thorax, and ten in the abdomen...
Page 498 - Traite d'Ornithologie," where many species are enumerated by name, without any description or reference by which they can be identified. Therefore, — § 12. A name which has never been clearly defined in some published work should be changed for the earliest name by which the object shall have been so defined.
Page 142 - Bermudas, has been in the autumnal months. The clue to these peculiarities attending the interchange of species of the two continents will be found in the study of the laws of the winds of the northern hemisphere, as developed by Prof. Henry and Prof. Coffin. These gentlemen have shown (see Prof. Henry's articles on Meteorology, " Report of Commissioner of Patents for 1856...
