Cambridge Medical Expedition to the Andes
This team carried out medical work in two villages and one small town (Have) on the Peruvian shore of Lake Titicaca, collecting the faeces of children up to eight years old to study intestinal parasites, relating this to socio-economic conditions. They established that prevalence of parasites is higher in rural than in urban areas. Two short treks were made to study altitude distribution of Satyridae (brown) butterflies of the group Pronophilini for the Natural History Museum.
