The Monthly Register and encyclopedian magazine was a British periodical published from 1802 to 1803. It was published by Charles and John Wyatt and edited by John Dyer Collier (1762–1825), the father of John Payne Collier. Henry Crabb Robinson's essays on Kant – amongst the very earliest notices of Kant in England – appeared there.
Henry Crabb Robinson's essays on Kant, which were the earliest published noticed of Kant in England, appeared in The Monthly Register.
I think it was difficult for the system because the text states that Robinson's essays on Kant were AMONGST the very earliest. It does not specifically state that they WERE the earliest, but they COULD BE. The key word that confused the system was AMONGST.
