HCR diary 12.6.1824
"called on Aders who had proposed my being shares in the Rhenish West India Co - a compant managed by C C Becher but as a servant only - Aders' brother is one of the founders - The society is the more deserving credit, from its not being pretentious - They offer only 4% interest with a bonus occasionally"
The Rhenisch West-Indische Gesellschaft founded in 1821 by Johann Jakob Aders crashed in 1828, was liquidated in 1832 and shareholders received only 10% back in 1843. For Carl Christian Becher (QV*).
