THE Report of the Inter-Departmental Committee on Sleeping Sickness (Cd. 7349, price 3d.), recently published, is a most valuable summary of present knowledge on the subject. The committee have taken the evidence of all the leading authorities on the subject, both British and foreign, and the enormous mass of evidence put before them (printed separately as Cd. 7350) has been very carefully sifted and analysed in the Report, which is signed by all members of the committee with certain reservations by two of them (Dr. W. A. Chappie, M. P., and Mr. J. Duncan Millar, M.P.), who have appended a separate memorandum embodying their opinions with regard to the game question.
