[18] I use the term ‘acquired’ without prejudice in the sense given to that word by Lamarck himself.

According to a report by Dr. Wiggins, the disease is confined in British East Africa, as in Uganda, to those areas in which Glossina palpalis occurs.

[24] Only last year (1905) Lieut. Tulloch, of the Army Medical Department, who with Professor Minchin was engaged in carrying on further researches for the Royal Society on the sleeping sickness at Entebbe in Uganda, became infected by the trypanosome, probably through an unobserved bite by a tsetze fly, and died of the disease soon after his return to England.

[25] Professor Minchin investigated this subject during 1905 in Uganda whither he went on behalf of the Tropical Diseases Committee of the Royal Society. He did not discover anything corresponding to the development of the malarial parasite in the gnat, but his investigations are not yet brought to a conclusion (December, 1906).

[26] Dr. Schaudinn died in 1906. He was only 35 years of age.
