One manuscript in the British Library ("Additional manuscript" 26319) has five different texts in four languages. The British Museum bought this manuscript from Erskine in February 1865. From 1811 are two Kurdish language glossaries that Muhammad Husain Khan made for John Malcolm at Bushehr, one a Persian–Laki glossary, the other a Persian–Ardalani glossary. Another is a Kurdish–English glossary. From the 19th century is a glossary of words in the Persian language and the Chagatai language, with words from the "Baburnama" of Babur. The final work in this manuscript is an anonymous work in Persian with the name in . This work is on the subject of metaphysics and consciousness. The copy of the "Jām-i Jahānnamāī"'s date is 1141 "anno Hegirae" (1729 CE). Erskine himself probably bound these five manuscripts into the present manuscript codex.
