For the latter Mr.Murray agreed to give him seventy guineas, "until the other poems shall be completed, when the copyright shall revert to the author," and also L20 for permission to publish the poem entitled "Kubla Khan." Next month (June 6) Murray allowed Coleridge L50 for an edition of "Zapolya: A Christmas Tale," which was then in MS.; and he also advanced him another L50 for a play which was still to be written.
"Zapolya" was afterwards entrusted to another publisher (Rest Fenner), and Coleridge repaid Murray L50.

Apparently (see _letter_ of March 29, 1817) Murray very kindly forewent repayment of the second advance of L50.

There was, of course, no obligation to excuse a just debt, but the three issues of "Christabel" had resulted in a net profit of a little over L100 to the publisher.

I would not take the works chronologically, but according to the likeness or contrast of the _kind_ of genius--_ex.
