collections:

Sumatra plants after his death in Herb. Junghuhn = Leiden [L]; some dupl. in Herb. Bog. [BO]. To our knowledge he made botanical collections only in Sumatra.

Several MSS, notes, and diaries, in the municipal library of Zürich, Switzerland.

literature:

(1) Author of mainly geological and mineralogical papers, published in Verh. Bat. Gen. K. & W. 1839 (on Borneo, Bantam and G. Gedeh), in Tijdschr. Nat. Gesch. & Physiol. 4, 1938, p. 359 (on Borneo), etc.
(2) S. Müller & L. Horner: ‘Fragmenten uit de reizen en onderzoekingen in Sumatra’ (Bijdr. Taal-, Land- en Volkenk. N.I. 2, 1854, p. 212-271; l.c. 3, 1855, p. 65-72, 193-249, 313-388). Herein the 2nd journey to Sumatra is dated in 1835, overlapping the 1st in the month of July etc.; in the same publication is mentioned a ‘redoute’ at Pitjarkolling which was not built before Dec. 1837 and was in use by the army when the party was there in Aug.-Sept.; so we may assume that the 2nd journey took place in 1838, and was not accompanied by S. Müller who had returned to Europe in 1837.
