Typed manuscript of Yumjao Singh's monograph on archaic Manipuri, mixed with Pettigrew's typed notes from WP/1/1. The monograph was put forward for publication by the Society but publication was not eventually undertaken.

This is likely item 3 listed In Mrs Pettigrew's letter dated 26 May 1943, being 'an arrangement of the material collected on the Archaic Manipuri in rough draft for the proposed Monograph on the subject' done by William Pettigrew and Yumjao Singh together.
