To the general impulsion which these trade-winds give the surface of the sea, we must attribute the equinoctial current, the force and rapidity of which are not sensibly modified by the local variations of the atmosphere. [* The limits of the trade winds were, for the first time, determined by Dampier in 1666.]

Aluminium, Gallium, Indium and Thallium - …

Aluminum is a major constituent of many common igneous minerals, including feldspars and micas. Gallium, indium, and thallium are less abundant than aluminum and tend to occur at low concentrations in sulfide minerals rather than in oxides. The chapter describes the preparation and uses of the aluminum, gallium, indium, and thallium.
