I have said above that, in consequence of the free and constant traffic with the lake-shore, it is impossible to say, in the case of a labourer coming from any lake-shore county, that he has not already been exposed many times to risks of infection. It is also impossible to eliminate these chances in the case of persons from the most inland districts, though they are less at greater distances from the We will lake and where, at the corresponding coast, the epidemic is less severe. suppose then, for the sake of argument, though it is a most unwarranted supposi tion, that, in the case of the inland provinces and counties, the visit of the labourers supplied by them to Entebbe was their first visit to an infected area, and their first and only chance of exposure to infection. If this were so, and I think it approaches absurdity to suppose it in the majority of instances, then the deaths given in the above table would represent the extent to which sleeping sickness has been con- tracted at Entebbe by these labourers and carried inland.* But, even on this supposition, the proportion is on the whole and in most cases very small, and there is no evidence of any considerable number of cases of this invariably fatal disease having originated in this way.

I believe, however, that these deaths really represent the prevalence of the disease or the death-rate among a very much larger number of people, namely, the total population of each county or province, and that the true percentages are not those in the table but smaller in the ratio of the number of the population to the number of imported labourers.

One thing at any rate is quite obvious, viz., that there is no direct relation between the number of deaths and the number of labourers supplied.

Take, for instance, Butambala, a so-called inland county a great part of which is only about 15 miles from the lake-shore. Here we find that 48 deaths occurred in 1905, and that 7,664 labourers have been supplied, a yearly average of 1,533 labourers, to which 48 deaths stand in the relation of 3.1 per cent. In Bugerere, where we have on one side the Victoria Nile with fly, and also the highly-infected Usoga (though not much traffic), we get a percentage of 5.2. In Buyaga, which supplied no labour, nine deaths are returned, which is about the average number for counties at a like distance from the lake. In Kabula we have a similar distance and a similar number of deaths, but, since it has supplied only a few labourers, we can calculate a death-rate as high as 30 per cent. Mawagola is in the same case, but Buganadzi, having an even smaller death return, and having supplied a very large proportion of labour, gives a death-rate, on the supposition we made above, of only 1.4 in 1,000. In Unyoro there exists the Lake Albert epidemic, of which we have, as yet, no exact returns, but in Ankolé and Toro, in spite of the labour supplied, there is no evidence of sleeping sickness, those cases and centres which have been rumoured to exist having turned out to be in reality beri-beri.

Map No. IV. has been prepared specially to assist in demonstrating the spread of the epidemic; the relation of hinterland to coast in the distance of its penetra- tion inland; and the proportion of its prevalence in the hinterland to the intensity of infection at the corresponding or nearest coast line. The same map will also be found to illustrate Appendix F. Map No. V shows fly distribution, fly-free areas, &c., &c., on the Entebbe Peninsula.

Thongh the natives are inclined to conceal their sick, it is found that they readily attribute to sleeping sickness any death from a chronic ailment or one which they do not understand, so that their returns are more likely to be over than under estinated, especially in these southern and western districts where beri-beri has been found to exist, and from many of which authentic cases of sleeping sickness have not yet been reported (Koki, Buddu, Turo, Aukols, e.g.).—A. D. P. Hodges.

APPENDIX F.

SEGREGATION AND TREATMENT BY MEANS OF ATOXYL.

In this appendix I include copies of my letter, No. 78/S.S.E., to His Excellency the Commissioner, and No. 81/S.S.E. to yourself, dated October 20th and October 25th, 1906, respectively, which allude to His Excellency the Commissioner's scheme for segregation and to my proposal to combine with it treatment by means of atoxyl.

His Excellency's scheme of segregation includes, in brief, besides segregation of the sick, deportation of reputed sound persons from a zone of two miles from the lake shore from all such places as are dangerous or such as it is impossible or unnecessary to deal with by clearing. These people will not be compelled to live at
