Surgeons Stanley, Goodsir, Peddie, and McDonald recommended to Sir John that the men’s diet be changed — fresh food when possible (although there was almost none except polar bear possible in the dark of winter, and they had discovered that eating the liver of that great, ponderous beast could be fatal for some unknown reason) and, failing finding fresh meat and vegetables, cutting back on the men’s preferred salt pork and beef, or salted birds, and relying more on the tinned foods — vegetable soups and the like.
