halo bates

[Gr. hals (gen it. halos ) = the sea, and bates =one that treads or covers; bainō = to walk, to go.] Entom.: A genus of Heteroptera, family Nepide. It is found on the surface of the sea within the tropics, often far from land. ( Swains on & Shuck ard .) hā-lõed, a. [Eng. halo; ed.] Surrounded with or as with a halo. "Elicit from the gloom some haloed face bending over me with strange pity."-C. Bronte: Jane Eyre, ch. ii. hălô-gěn, s. [Gr. hals salt, and gennaō -to produce.] Chem. The electro-negative radical of a haloid salt. This term is also used for the monad elements chlorine, bromine, iodine, and fluorine, as their sodium salts resemble sea salt, which is chloride of sodium, NaCl. The physical properties of Cl, Br, and I, correspond with the difference of their atomic weights, Cl 35.5, Br 80, and I 127, the weight of bromine vapor being the mean of that of chlorine and iodine. Chloride is a gas, bromine a liquid, and iodine solid at temperatures. Chlorine has the greatest chemical affinity for hydrogen, and iodine for oxygen, that of bromine being intermediate.
