The 'Bower Manuscript' is a collation of seven treatise manuscripts, compiled into a larger group and another a smaller one. The larger manuscript is a fragmentary convolute of six treatises (Part I, II, III, IV, V and VII), which are separately paginated, with each leaf approximately 29 square inches (11.5 inch x 2.5 inch). Part VI is written on smaller folio leaves, both in length and breadth, with each leaf approximately 18 square inches (9 inch x 2 inch).[6] The larger group and the smaller set likely came from different trees or region.
