Enclosure 3 in No. 19. DEPARTMENT OF PROTOZOOLOGY.

Report by Dr. John G. Thomson, Director of Protozoology, London School of Tropical Medicine and Hygiene, for the half-year ending 31st October, 1924.

DURING the summer term of the London School of Tropical Medicine a course in Protozoology was given to seventy students, and in the autumn, under the London School of Hygiene and Tropical Medicine, a course was given to a class of seventy- three. The work in the class is so arranged as to give the students, who are all qualified medical practitioners, as great a practical experience as possible of Protozoa, which are parasitic in man or are of economic importance at home and in the tropics. Three advanced students have received tuition in the Department. The course of instruction given to advanced students chiefly consists of methods of Protozoal technique which it is not practicable to give to such large classes as those mentioned above.

In the summer term twelve Medical Officers from mental hospitals were given special instruction on malaria. The object of this special course was to familiarize these Medical Officers with malaria in all its aspects, but more especially the appear- ances of the parasite in the blood of man, and the sexual cycle in the Anopheline mosquito, so that in treating general paralysis of the insane by giving the patients malarial fever, they would be able to control the secondary disease accurately, and also to correlate their findings.

Dr. E. K. MacKay worked for some time on the protozoa in the intestine of the cockroach, with special reference to the amoeba. Endamoba blatte is the type species of its genus, and the closeness of its relationship to certain of the ambæ of man is a matter of controversy at present. Unfortunately, the work was inter. rupted and no definite conclusion has been arrived at.

Dr. Lamborn, Government Entomologist, Nyasaland, was an advanced student in this Department and was engaged on the study of protozoal technique in general, and also on trypanosomiasis of man and animals, especially the life cycles of the parasites in the vertebrate and insect hosts.

Miss M. J. Triffitt. M.Sc., has continued her investigations into the intestinal protozoa of certain animals. A copy of her paper "Note on an Eimeria, N. Sp., found in the Freces of an Eland" is sent along with this report.

Dr. Andrew Robertson, Assistant in Protozoology, has published a paper on the causative organism of rat-bite fever in man.

I have published as one of the Research Memoir Series (No. 6), of the London School of Tropical Medicine, my findings during the two expeditions to Southern Rhodesia in 1922 and 1923 to investigate the causation of blackwater fever.

II. SLEEPING SICKNESS.

No. 20.

TANGANYIKA TERRITORY.

THE ACTING GOVERNOR to THE SECRETARY OF STATE. (Received 6th June, 1922.)

(No. 347.)

SIR.

Government House. Dar-es-Salaam, 12th May, 1922.

I HAVE the honour to transmit herewith a copy of a memorandum by the Acting Principal Medical Officer reporting an outbreak of sleeping sickness in the Mwanza district.

2. The necessary precautions as regards segregation, &c., have been taken, and in accordance with Dr. Shircore's recommendation I have asked the Governor of Uganda to allow Dr. Lyndhurst-Duke to proceed to the area affected, and to conduct the necessary investigations in order that the specific type of infection may be determined.

3. I have also despatched Mr. Swynnerton, Game Warden, to the Mwanza District to inaugurate a campaign against the tsetse flies.

4. Before his departure Mr. Swynnerton submitted a report, a copy of which I enclose, suggesting that on his return from leave, which is now due, a thorough study of the tsetse fy problem be made in order to obtain a clear idea of the exact distribution of sleeping sickness in the Territory. The Acting Principal Medical Officer entirely agrees with Mr. Swynnerton, but although the Veterinary and Agricultural Departments will help as far as possible, I fear that with our present staff the assistance which the Veterinary Pathologist and the Entomologist will be I HAVE the honour to inform you that a telegraphic report was received from the Medical Officer, Mwanza, to the effect that 70 deaths were reported from Ntussu. 2. An examination of 25 sick apparently afflicted with the same signs and symptoms as those who died proved that 12 were suffering from Trypanosomiasis.

3. This diagnosis was arrived at by microscopic examination of the blood, and has been since confirmed by the Director of the Laboratory, to whom slides were able to render will only be on a limited scale,

transmitted by Dr. Maclean.

I have, &c.,

A. C. HOLLIS,

Acting Governor.

Enclosure 1 in No. 20. The Acting Chief Secretary, Dar-es-Salaam. The Honourable

18th April, 1922. Principal Medical Office, Dar-es-Salaam, 4. The necessary instructions as regards segregation of the sick, other prophy- laxis measures, and the methods of treatment to be adopted were immediately issued, and a staff of three dressers sanctioned for the care of the sick.

5. I am now informed by telegram that only Glossina of the Morsitans Group has been discovered, and that the affected area lies south of Duma and to east and west of the River Ssimiju. Map Section B. 3, subsection D. 6, 7, 9, 13 and 14. This is part of an isolated fly area, and is not continuous with the Tabora, Shin- yanga, Mwanza area, which is not therefore affected.

6. It is of great importance to ascertain, definitely, whether these cases are, or are not, cases of the Uganda or Rhodesian type, as the latter has hitherto never been reported from further north than latitude. S 9°, whereas Glossina Morsitans is distributed widely throughout Eastern Africa, including parts of Uganda.

7. The situation of the epidemic area is in such close proximity to Lake Victoria, lying as it does on either side of a river, which flows into it, that it is not possible to eliminate entirely the probability of an infection caused by Glossina Palpalis, for it is well known that this fly may be found for miles up rivers flowing into Palpalis infested lakes.

8. From what the Medical Officer, Mwanza, has reported, I am, however, personally inclined to the view that the infection is one of Rhodesiense, rather than of the Uganda form of sleeping sickness, but for the reasons given above animal experiments are required before this subject can be cleared up.

9. For this purpose I recommend that the Uganda Government be requested to loan the services of Dr. Lyndhurst-Duke, who is an expert on this aspect of the subject, for a period of time sufficient to enable him to collect material for research,

J. O. SHIRCORE, Acting Principal Medical Officer.

To the Honourable

Enclosure 2 in No. 20.

Game Department, Kilosa, RECENT correspondence and the present outbreak of sleeping sickness near

24th April, 1922. Mwanza emphasize the necessity for turning all available energy on to the tsetse work of the Territory.
