Talk:Structural theory

Quotation from Butlerov article
Footnote number 2 does not provide a reference to the quotation in the text of the article; it is a URL that directs to a site of the London School of Economics. If not clarified or corrected, I will remove both the footnote and the text quotation.Ajrocke (talk) 14:25, 20 March 2016 (UTC)
