Note 1 — CHAP. II.

: "It is worthy of remark, that although all the troops in Ceylon have occasionally, but at rare intervals; suffered severely from cholera, the disease has in very few instances attacked the officers; or indeed Europeans in the same grade of life. This is one important difference to be borne in mind when estimating the comparative risk of life in India and Ceylon. It must be due to the difference in comforts and quarters, or more particularly to the exemption from night duty, by far the most trying of the soldiers' hardships. The small mortality amongst the officers of European regiments in Ceylon is very remarkable."—Note by Dr. CAMERON, Army Med. Staff.
