From Drei Jahre in Amerika pg. 383:
The following takes place in Louisville, Kentucky in June of 1860.
A German synagogue called Adath Israel invited the author to a meeting as the guest of honor. One subject raised at the meeting was that a Christian couple had applied to them for conversion to Judaism. A man stood up and addressed the members: "Conversion to our religion requires instruction in our precepts. Some of the most important of which are observance of the Sabbath and festivals. In the case of women, observance of the laws of mikveh are most important. How can we, who don't obey these commandments ourselves and don't even have a mikveh impose these on others? We would only publicize our own shame (schande) to have departed so far from these divine commandments." They were embarrassed, reached no decision and the matter was postponed.
