THE Expedition numbered 28 members on setting out; of these 3 were 

 lost on a sledge journey in 1907, the remaining 25 returned home 

 well and strong. 



The health of the Expedition was excellent during the whole time; 

 the cases of sickness occurring were all, with a single exception, light. 



On the voyage to Greenland we had a number of cases of sea-Sick- 

 ness, but only two of these were obstinate. 



A number of cases of acute gastro-enteritis with pains, 

 much A'omiting and severe diarrhoea occurred simultaneously twice on 

 the voyage; the last and worst of these "series" occurred in the Po- 

 lar Sea and was probably caused by the cold, foggy weather. The 

 general character of the cases seemed definitely to exclude the idea 

 of poisoning. 



At the beginning of the expedition a no small number of small 

 lesions especially of the hands occurred among the inexperienced. 

 Almost aU of these wounds quickly healed without any sign of infection. 

 On the other hand, there were several cases of infection from wounds 

 after we came amongst the drift-ice, at which time hunting began. I 

 think it probable that the infection arose during the skinning and cut- 

 ting up of the animals shot, the more so as I found bacteria in the intes- 

 tines of these in all cases examined. Two cases of panaritium of 

 relatively long duration, which I treated during the first \\anter in Green- 

 land, occurred just in the persons who had been working wth walrus 

 fiesh. 



In the beginning of the \\'inter, when the severe cold suddenly set 

 in, rheumatic pains were not uncommon especially in the night- 

 time, when we were exposed to draughts in the untight berths or trou- 

 bled by the large quantities of ice in those better closed. 



During the same period several of the members of the Expedition 

 were troubled at nights by a frequently occurring desire to 

 m i с t u г a t e. In none of the cases examined was there anything 

 pathological in the urine, nor was polyuria found; the mode of life was 

 quite the same as during the rest of the Expedition. Similar cases have 

 been observed on the Swedish South Polar Expedition. Dr. Ekelöf 

 holds the view that they arose from improper food, but so far as our
