Abstract
TWO recent numbers of the Annals of Tropical Medicine and Parasitology (vol. iii., No. 2, October 20, and No. 3, November 1) contain six memoirs, of which four deal with problems relating to trypanosomes and the diseases caused by them. Messrs. Kinghorn and Montgomery discuss the important and difficult question of the flagellates found in the intestine and proboscis of tsetse-flies caught wild, on the basis of observations made by them during their expedition to the Zambezi, 1907–9. In Glossina palpalis collected by them on Matondwi Island, at the southern extremity of Lake Tanganyika, an island that has been uninhabited for twenty years, they found, out of 185 flies dissected, no fewer than seventy-eight, or 42.1 per cent., harbouring flagellates in the intestine, a percentage which far surpasses all previous records from other places; no parasites were found, however, in the proboscis. In Glossina morsitans collected near Kambole, about fifty miles west of Abercorn, nine out of 113 flies examined, or 7.8 per cent., were found infected with flagellates in the intestine, and seven out of thirty-one flies examined, or 21.2 per cent., were found to contain flagellates in the proboscis.
