Hmm... it appears this text is different from Isaac Newton's Emerald Tablet of Thoth.
http://en.wikipedia.org/wiki/Thoth
"A text entitled The Emerald Tablets of Thoth-The-Atlantean has been claimed to have been translated by a man named Doreal [in 1925]. The introduction claims them to be written by an Atlantean Priest-King named Thoth, who settled a colony in Egypt after Atlantis sunk. Doreal further claims the texts are 36,000 years old.[48] Regardless of the authenticity of the text, it contains much Hermetic and Egyptian symbolism that Doreal misses."

"The oldest documentable source for the text is the Kitab Sirr al-Asrar, a pseudo-Aristotelian compendium of advice for rulers authored by Abd al-Qadir al-Jilani in around 800 AD."

"One translation, by Isaac Newton, found among his alchemical papers"
