He also published reports on the Makerstoun and Trivandrum observatories. He was awarded the Keith Medal of the Royal Society of Edinburgh and the 33: 771: 269:, the highest peak in Travancore, and helped to found the museum and zoological gardens. He had a bifilar magnetometer setup on Agastyamalai between 1855 and 1858. This museum was later demolished and replaced by what is now called 182:. Broun suffered heart palpitations, possibly due to extended overnight study. He then hired John Welsh as an assistant. In 1850 he moved to Paris, also marrying Isaline Vallouy, daughter of a priest from Canton du Vaud. Colonel 620:"XXIV.β€”On the Lunar Diurnal Variation of Magnetic Declination at Trevandrum, near the Magnetic Equator, deduced from Observations made in the Observatory of His Highness the Maharajah of Travancore, G.C.S.I." 254:. Broun was sent to study geomagnetism at a period when the British Academy was interested in studying it on a global scale. Trivandrum was close to where the magnetic equator lay at the time of Broun. 178:, in Scotland and when a director was sought, Forbes recommended Broun who worked there from 1842 to 1849. The observations Broun made at Makerstoun were published in the 261:. Broun's assistants in Kerala included J. Kochukunju (Cochoocoonjoo) and E. Kochiravi (Cocheravey) Pillai.
