the planet Mars. The etymology of the name is unknown. The sphere of Mars is the fifth sphere of the planets.

, also nus̲h̲ādir , naws̲h̲ādir , Sanskrit navasadara , Chin, nao-s̲h̲a , sal-ammoniac. The etymology of the word is uncertain; perhaps it comes from the Pahlavi anōs̲h̲-ādar “immortal fire” as we find the form anūs̲h̲ād̲h̲ur in Syriac. The oldest references to the occurrence of salammoniac in a natural state are in the reports of ¶ Chinese embassies of the 6th-7th centuries, which were the subject of very full investigation in connection with a geological problem, the question of volcanoes in Central Asia, by H.J. von Klaprot…

, the pearl. The ancient legend of its origin is found at great length in the Arabic authors, first in the Petrology ( Steinbuch , ed. Ruska) of Aristotle, then with variants in the Rasāʾil Ik̲h̲wān al-Ṣafāʾ and the later cosmographers. According to it, the aṣṭūrūs (’οστρεῖον) rises from the depths of the sea frequented by ships and goes out to the ocean. The winds there set up a shower of spray and the shells open to receive drops from This; when it has collected a few drops it goes to a secluded spot and exposes the…

soap (cf. English soap), has penetrated through Latin sapo and Greek σαπών as a loanword to the East also. According to Pauly-Wissowa, ( Realenz. d. klass.

There can, however, be no doubt that soap came into use in the middle ages along with other lathery lotions and in addition to its uses for clea…
