Uploaded to Panel C12-1 in Canynges Coffer, 12th September. This is the second printing, which appeared in the Miscellanies in Prose and Verse of Thomas Chatterton, 1778.
The manuscript is missing, it being likely that Chatterton sent the original to the publisher of the London Magazine in May, 1770 (first printing).
