Sampford, Braintree, April 7. 1851.
_Sempecta at Croyland._--DR. MAITLAND has so kindly answered your
correspondent's Query respecting his work on Mesmerism, that I venture to
ask him another, through the medium of your pages. Where can be found the
poem respecting the old soldier monk at Croyland (or Sempecta, as Ingulphus
calls him), from which DR. M. has given extracts in p. 305. of his _Dark
Ages_?
