Page 384 - ... a large lake called Periyakolam. A small channel on the north continues easterly; it was recently cut to prevent the injurious consequences of inundations, which are represented to have frequently happened previous to this undertaking. The Vigay, retaining its name, proceeds eastward for six miles, losing itself in a salt-marsh which extends nearly five miles in length, and about a mile and a half in breadth, where, from the saline nature of the soil, a considerable quantity of salt is extracted....
Page 200 - Thermometer should be read off, and registered hourly, and the precise hour and minute of each reading should be especially noted. For obvious reasons, however, the commencement of every hour should, if practicable, be chosen, and every such series of observations should be accompanied by a notice of the means used to obtain the time, and, when practicable, by some observation of an astronomical nature, by which the time can be independently ascertained within a minute or...
Page 297 - Since calculations have been made on the progress of agriculture in the different zones, and on the temperatures under the influence of which corn will flourish, it has been found that, beyond the latitude of 45, the produce of wheat is nowhere so considerable as on the northern coasts of Africa, and on the table-lands of New Grenada, Peru, and Mexico.
Page 203 - ... proportion, it ought, if possible, to be ascertained. The data necessary to be known are — first, the internal and external diameters of the tube — secondly, that of the cistern containing the mercury, at the surface, where the tube plunges into it. These particulars, as they must be known to the maker, ought to be inquired of him, and indeed ought to he engraved conspicuously on some part of the instrument.

Page 196 - The great importance of possessing an exact and carefully registered account of the variations of the barometer, thermometer, and other meteorological instruments, and of the winds and weather...
Page 403 - It was hardly to be expected that we should find, amid the petrified remains of animals of the ancient world (remains which have been buried for countless centuries in the deep foundations of the earth), traces of so delicate a fluid as the ink which was contained within the bodies of extinct species of Cephalopods, that perished at...
Page 189 - The tail, if a thick one, as that of a shark, may be taken off a little below the anus, and the trunk alone preserved for examination. If the trunk be too large, it should be cut through above the pelvis, and the parts contained in the hinder portion, as the claspers of the male, should be preserved in spirit.
Page 205 - ... cautiously over a very small clear flame of an oil lamp, till the mercury rises to the very top of the tube, and fairly unites with the globule there awaiting it. Let the bulb cool, and the mercury will sink in one united column; if not, heat it again. When this is accomplished, the index may be set loose, by withdrawing the magnet, and restored to its proper position in the tube. "A self-registering thermometer may be advantageously left (properly secured) for a whole year, or parts of a year,...
Page 403 - ... fluid as the ink which was contained within the bodies of extinct species of Cephalopods, that perished at periods so incalculably remote; yet the preservation of this substance is established beyond the possibility of doubt, by the recent discovery of numerous specimens in the Lias of Lyme Regis...
