He reaches the conclusion that scurvy in general is caused by poisonous substances developing as the outcome of certain autolytic and spontaneous, non-bacterial processes in preserved animal products (meat and fish) which in most cases have constituted a large part of the food of arctic and antarctic expeditions.
