Instructions for observing air temperature, humidity, and direction and force of wind

Description of instruments.-The temperature and humidity of the air are obtained from the simultaneous observation of a pair of mercurial thermometers termed the dry and the wet bulb. The air temperature is given by the dry-bulb thermometer, and the humidity is obtained from the combined readings of both. The wet-bulb thermometer differs from the dry-bulb thermometer only in having its bulb covere

A dictionary of altitudes in the United States (second edition)

I have the honor to transmit herewith the manuscript of a second edition of a Dictionary of Altitudes, the first edition having been published in 1884.
