The source is biased: has russian authors, the very article is labeled by the authors as "encorrected", and it hasn`t got a single reference. I would like to know what the hell is with that "1792"? Pure sophistry from Mauco... Also, regarding the "subsequent research", please explain how, by whome, and when was the research done. Also, explain how much you get payd Mauco for doing this, just for curisity... Whas it you life dream to be a prostitute for the Smirnovs... oups, a... a... how was that??? ahh, yes, "an independent scholar and researcher"  hah ha hahaha...
