Space forbids a full description here, but there are two important points to which I must refer: _Dried cereals_ by themselves do not contain active anti-scorbutic vitamin, but if made to germinate the green shoots which sprout from them are rich in it. This is a point of immense practical value, the application of which is obvious. With regard to _fresh meat_, it has been shown by Stefansson in the North, and by members of the _Endurance_ expedition in the South, that health can be maintained on a purely meat diet, and that fresh meat, if taken in sufficient quantity, is effective to cure scurvy. Stefansson, in the _Friendly Arctic_, says that it must be eaten raw or very much underdone, but our experience in the South showed that this is not necessary. In fact, a certain degree of cooking is advisable. He states also that putrefactive meat is an effective cure for scurvy. This I think is dangerous teaching; in any stage of scurvy anything putrefactive should be avoided if possible unless there is nothing else. Those general readers who desire to learn more of this most interesting disease are referred to the bibliography at the end of the report. On this expedition there was no scurvy, and no risk of it, for we were never long enough away from sources of fresh food. Yet I would emphasize the necessity of strong anti-“deficiency disease” measures in polar work, whatever the programme may be, for in the pack ice accidents may at any time occur leading to altogether unforeseen conditions as regards food supply. _Frost-bite_ is a condition well known to all polar explorers. If neglected it may lead to most crippling results, and, like scurvy, requires careful preventive measures. The parts of the body most commonly affected are the exposed parts of the face, especially where the skin is drawn tight over underlying bone, e.g. the sides of the nose, the cheekbones and the chin; the ears, the fingers and the toes. In parts other than the fingers and toes the condition is usually not serious, for frost-bite of the face and ears, if neglected, may cause disfigurement, but no real crippling. It is a good practice for men in company to scrutinize each others’ faces, and a valuable piece of equipment is a small mirror in which a man without companions can examine his own face. Frost-bite of the fingers, though more serious, is usually quickly recognized and promptly treated. Frost-bite of the toes and feet is an extremely dangerous condition and may have far-reaching results. The danger lies in the fact that its incidence is often unknown to the man attacked, and, though he may suspect its onset, he may neglect to examine his feet, for polar footgear is elaborate and cumbersome, examination of toes on the march means a halt, and a certain amount of time is consumed in unfastening and securing the foot-coverings.
