Letter from Henry Thomas Colebrooke to Nathaniel Wallich in which he congratulates Wallich for his success in research in Nepal. Colebrooke discusses publications to send to Wallich.

Wallich will be proposed for the Linnean Society after the Easter break and can also be proposed to the Geological Society. Colebrooke is keen to promote study on the geology of India and states information that he would like to collect. Colebrooke is pleased that Wallich is in contact with Mr Alexander of the Cape of Good Hope.
