Copies of letters sent to the Government of Bengal by botanists, including Robert Kyd and Dr William Roxburgh, reporting on the cultivation of Mawah and Teak trees, the discovery of a new species of Indigo (Nerium tinctorium), and attempts to propagate the Cochineal insect in the Calcutta Nopalry garden. The letters are written in a large, consistent italic cursive. The writer often embellishes capital letters with flourishes, and uses ampersands (&). Contracted words are often indicated with superscript final letters.
