Helos

Helos , a town of ancient Greece, in the territory of Laconia, situated in a fertile plain near the Eurotas and the sea. Its foundation was ascribed to Helms, the youngest of the sons of Perseus, and in very early times it appears to have been the principal town of that region. On being taken by the Dorians, its inhabitants, as a punishment for the obstinacy of their resistance, were reduced to slavery, and their name, according to some writers, became in time the general designation of the Spartan bondmen. In the age of Strabo Helos had dwindled into a small village, and in that of Pausanias it was a heap of ruins. Its site was probably near Bizani, where there are some Hellenic remains. - Helos at the present day is the name of a district in the plains on the banks of the Eurotas, extending from the mountain of Bizani to the frontier of Maina. Most of the villages of the district are on the low hills which encircle the plain.

Hematine

Hematine , (Gr. Hematine 0800428 blood), the coloring matter of the red globules of the blood. Hematine belongs to substances of the albuminoid class, consisting of carbon, hydrogen, nitrogen, and oxygen, with which is associated a small proportion of iron. It forms a little over 1 1/2 per cent. of the substance of the blood globules, but even in this small proportion is sufficient to communicate to them, and to the whole mass of the blood in which they are suspended, the strong and rich deep red color by which they are so readily distinguished. It is rapidly altered in hue by the action of chemical substances, and has not therefore been made available in the arts for the production of dye-stuffs. It is soluble in water, and a very small quantity of hematine will communicate a distinctly red tinge to a very large quantity of fluid.
