During the voyage of the _Quest_ there was little sickness. A number of casualties occurred, most of them trivial and easily dealt with, none producing serious results. There was one death: Sir Ernest Shackleton. The cause was _atheroma of the coronary arteries_. The condition was a long-standing one and in my opinion was due to overstrain during a period of debility. In his history there are many occasions when it may have been produced. The scurvy which he developed during the southern journey of the _Discovery_ expedition may have produced lasting results. It has been stated that his collapse caused the failure of that journey. I must make it plain that the development of scurvy in an individual during a sledge journey is not in any way the fault of the individual, but results from faulty organization. Sir Ernest Shackleton has never had a single case of scurvy, or any condition allied to it, in any party under his charge. His condition may have been produced during his own great pioneer journey towards the South Pole. What is remarkable is that in such an advanced condition he was able to carry on as he did. It shows, psychologically, a wonderful will power and an unyielding determination to overcome difficulties. In this respect may be noted one of the last things which he wrote (in a final letter to Mr. Rowett): “Never for me the lowered banner, Never the lost endeavour.” In other psychological respects he was remarkable, as is seen in the combination of a happy and apparently carefree temperament with an ability for accurate and detailed organization. As a leader he was always “boss.” He was condemnatory of shortcoming and exacting in the service rendered by subordinates, yet he drew from all who worked for him a deep liking and an unfailing loyalty. His physical qualities are well known. As a living organism he was wonderful. BIBLIOGRAPHY BASSETT-SMITH. “Scurvy; with Special Reference to Prophyllaxis in the Royal Navy.” _Proc. Roy. Soc.
