Mr. J. McConnell Sanders has presented specimens of Lathrodectes mactans, a venomous spider of tropical America, the bite of which he represents to be respon- sible for much suffering and for several deaths annually in the labour forces of a commercial company in which he is interested. So much trouble does this small but horribly venomous spider cause, in this particular company, that Mr. Sanders paid a special visit to the School to discuss methods of radical treatment.

Col. Dodds, R.A.M.C., has given some valuable specimens from British Guiana. Since the last half-yearly Report was submitted news has been received from Dr F. W. O'Connor, Assistant in the Department, of his safe arrival and com- mencement of work in the Gilbert and Ellice Islands.

My own time, apart from routine work and the vicissitudes of the removal from the Albert Dock establishment, has been devoted mainly to the preparation of material for teaching purposes and to the Museum.

REPORT OF Department of HELMINTHOLOGY FOR THE HALF-YEAR ENDEL

30TH APRIL, 1920.

I HAVE the honour to submit my half-yearly Report as Director of Helmin- thology at the London School of Tropical Medicine, and to append three reprints of papers which have come to hand since the previous Report was forwarded.

During the period under review the Department was removed from the Albert Dock to the new premises provided for the School in Endsleigh Gardens. This removal was completed by the end of January, 1920, and a considerable amount of time since then has necessarily been devoted to reorganization.

The courses of Helminthology in the General School curriculum were held as usual in December and March, and for the first time the whole of the Helmintho- logical instruction in the School was entrusted to me. Owing to difficulties con- nected with the removal of material, etc., it was not found possible to hold an advanced class.

Investigations on the parasites of domesticated animals, with special reference to their identification by the character of the eggs, were continued under a Board of Agriculture Grant held by Miss M. Turner, M.Sc. An arrangement entered into with the Zoological Society of London last summer enabled Dr. G. M. Vevers to make a systematic examination of the parasites of all animals dying in the Zoo- logical Gardens, and to obtain material for the study of life-cycles. In January, 1920, Dr. Vevers was awarded a Beit Research Fellowship tenable in this Depart-

ment.

In conjunction with Dr. J. A. Murray, Director of the Imperial Cancer Research Fund a series of observations have been commenced on the parasite Gongy- lonema neoplasticum, which has been found by Fibiger to induce cancer in the stomach of rats in over fifty per cent. of those experimentally infected.

With a grant of £50 from the British Medical Association, Mrs. Arthur Williams has continued her work on the guide to the medical periodical literature to be found in the various libraries of London.

The Medical Research Council has undertaken to assist the research work of the Department by providing a research Assistant and expenses for an investiga tion into the Helminth infections in this country. Work upon this has. however. only just commenced, and there is nothing yet for report.

I am, &c..

R. T. LEIPER.

REPORT OF PROTOZOOLOGICAL DEPARTMENT FOR THE HALF-YEAR ENDED)

30TH APRIL, 1920.

I HAVE the honour to report the following progress in the Department of Protozoology:

(1) The change from the Albert Docks to the new premises and the equipment of the new laboratories has occupied much time, but is now almost complete.

(2) For the first time the whole of the subject of Protozoology is taught by this Department. Previously part of the subject was taught by the Department of Tropical Pathology.

(8) Work has been facilitated by the appointment of a full-time Demon- strator (Dr. Robertson) to the Department. for purposes of teaching and research.

(4) During last session four medical men availed themselves for special advanced work in Protozoology, and during this session three students are working at special work. The ordinary class was conducted as usual.

(5) I enclose a War Office publication containing observations on malaria, by myself. These researches cover a long period of time.

To the Secretary of State for the Colonies.

J. G. THOMSON, Director of Protozoology.

THE LONDON SCHOOL OF TROPICAL MEDICINE to COLONIAL OFFICE. (Received 10th December, 1920.)

SIR,

London School of Tropical Medicine, 3rd December, 1920.

I HAVE the honour to submit herewith the half-yearly reports of the follow- ing special departments of the School :-

Entomology: Professor A. Alcock, I.M.S., C.I.E., F.R.S.; Helminthology: Professor R. T. Leiper, M.D., D.Sc., F.Z.S.; Protozoology: Dr. J. Gordon Thomson;

together with a report on entozoa collected from animals which died in the Zoological Gardens of London during eight months of 1919-1920, by Dr. G. M. Vevers, F.Z.S., Beit Memorial Research Fellow and Demonstrator in Helminthological Department.

Since the last report was forwarded, there has been a marked increase in the number of students attending the School. The total number now under tuition is seventy, which is larger than any previous session in the history of the School. This increase of students is partly in consequence of the return of many medical graduates from war service, but it is also attributable to the facility with which the School can now be approached in its new position in London, in close proximity to University teaching.

On the 11th November, His Royal Highness the Duke of York formally declared the new premises open, when there was a very large attendance of staff, teachers, and past and present students. His Royal Highness was received by Viscount Milner, Secretary of State for the Colonies, who in addressing the Prince, dwelt upon the advantages that would accrue to tropical medicine by the increased facili- ties that are now afforded.

Reports have been received from Dr. O'Connor, who is carrying on his research work in regard to Filariasis in Samoa, and the School has to acknowledge the services rendered by the Colonial Office in connexion with this expedition.

A project for an expedition to British Guiana is now engaging the attention of the School.

I am, &c.,

P. MICHELLI,

Secretary.
