The concurrence of each well authenticated case should invariably be reported, with such details as can be gathered with regard to his past history, during the last seven years, specially noting where he came from, what places he has visited during that time, and what work he has been employed upon.

Enclosure 2 in No. 49.

(Circular. No. 19 of 1905.)

Commissioner's Office, Entebbe, Uganda, July 6, 1905. In June, 1903, Colonel Bruce addressed District and Medical Officers of the Protectorate, and asked their assistance in regard to points affecting sleeping sickness.

The matters in connection with which he particularly asked for information were the following:-

1. In what kind of place the fly is found? (in marsh, banana plantation,

bank of river, lake, &c.).

2. If it frequents bush or open places?

3. Is it numerous ?

4. What animals does it bite?

5. Does sleeping sickness occur in the same places as the fly, distinguishing between imported cases and those which have been infected on the spot?

A great deal of very useful information was received from many of the districts, which materially assisted Colonel Bruce in preparing a partial map of the fly- infected areas, with which it was found that the area of infection coincided.

Further information in this connection is urgently needed by the Sleeping Sickness Commission.

Below is noted an extract from a memorandum by the Royal Society on the enquiries which it is considered could be usefully undertaken by local officers:-

(1.)

A careful mapping out of the distribution of the various species of tsetse flies over the whole area where sleeping sickness is spreading or seems likely to spread. As the disease may possibly be carried by several or all of the species of these flies, there is an obvious danger of the disease spreading outwards in all directions from Uganda. (2.) "This inquiry should be started without delay in Uganda, and every available assistance from the local population should be made use of. The distribution of the fly on the Nile between the Ripon Falls and Fajao likewise calls urgently for attention.

(3.) "It would also be well, as part of this investigation, to institute a careful search for the presence of the fly on any of the rivers which show open water, such as the Kafu, and to find out, if possible, under what con- ditions the flies are enabled to extend so many miles inland in Usoga, while in Uganda they are restricted to the lake shores.

(4.) "A more complete determination of the areas wherein sleeping sickness occurs and on a larger scale than has hitherto been attempted. The necessity of this investigation is obvious. If, for example, a large number of natives were required for work in the Nile Valley or else- where, it is most important that they should be taken from a district absolutely free from the disease. Again, if natives were taken from an area of sleeping sickness into a district where a tsetse fly abounds, the disease would be at once communicated to the natives of that district. As no large scheme for prevention can be attempted until these areas have been mapped, it is obvious that no time should be lost in undertaking this work. Since the autumn of 1903 little has been done by the officials, chiefs, and others to add to our knowledge of the distribution of the fly and of the disease. Had this work been con- tinued since then it might, not improbably, have been by this time completed."

It is requested that you will give all the information on the points noted, so far as your district is concerned and so far as you have the means of so doing. Oppor- tunities will be found when you are on tour and you could usefully urge the chiefs to send out men to examine the localities not already reported on, and to send in specimens of the flies, carefully noting in each case the particular locality in which they are found.

In cases where there are doubts as to what the tsetse fly really is, the Sleeping Sickness Commission will be happy to send specimens to any district on application being made to them.

Each Collector should keep in his office a map of his district, in which should be entered in black dots the location of the tsetse fly, and in red dots the places where sleeping sickness is known to have occurred, and this map should be con- stantly kept up to date as further information is received.

Since it is of the highest importance to ascertain, if possible, in what localities the fly breeds, and what kind of environment it prefers for this purpose; and since, further, it is probable that in the breeding places the female flies will be found to be as numerous as, if not more so than, the males; it would be a great help if those who collect flies would do so in such a way as to throw light on this point. For instance, the flies collected near a marsh should be put into a packet separate from those captured in a banana plantation, the former marked "marsh," the latter "banana plantation," and so on for each kind of collecting ground. And each packet of Ries should be collected only from a limited and uniform area, the nature of which should be indicated on the packet. Any notes which the Collectors could furnish in this way as to the localities in which the flies were collected would be most

valuable.

It has been observed in Entebbe that in most localities the numbers of the males are far in excess of the females.

A prominent place will continue to be given to sleeping sickness in the monthly reports furnished to His Majesty's Commissioner by District Officers. Here should be entered all information obtained during the month regarding the progress of the disease, the number of deaths, any localities in which the disease is reported to have freshly occurred, whether the disease is supposed to be on the increase or decrease, and generally all matters which may be likely to help in the investigations which are being carried on by the Sleeping Sickness Commission.

The earnest attention of all District and Medical Officers is requested to the instructions contained in this circular.
