ADVISORY COMMITTEE FOR THE TROPICAL DISEASES RESEARCH FUND.

MINUTES of meeting held at the Colonial Office on 17th January, 1922.

Present:

SIR H. J. READ, Chairman. SIR PATRICK MANSON.

SIR R. HAVELOCK CHARLES. PROFESSOR J. W. STEPHENS.

MR. A. BEVIR, Secretary.

1. The minutes of the previous meeting* were confirmed.

2. The Committee directed that a letter should be sent to Sir J. West Ridgeway expressing their regret at his retirement and their thanks for his services as Chairman of the Committee.

8. The Committee considered the financial position of the Fund, and decided to make no change in the grants to the London and Liverpool Schools of Tropical Medicine (£1,000 each annually). They also decided to make an additional grant of £100 to the £300 already granted to the Quick Laboratory, making a total grant for the current year of £400..

4. The Committee considered an application from the University of London for a grant towards research in Protozoology. In view of the fact that £200 of the grant already made remained outstanding, they decided that they would not consider the application for the present, but would be prepared to give sympathetic consideration to a further application when the grant is exhausted.

5. The Committee discussed and commented on various papers which were referred to them by the Colonial Office.

THE LONDON SCHOOL OF TROPICAL MEDICINE to COLONIAL OFFICE.

(Received 8th June, 1922.)

SIB,

London School of Tropical Medicine,

Endsleigh Gardens, Euston Road, N.W.I., 6th June, 1922.

I SEND you herewith the usual half-yearly Reports in regard to Entomology and Helminthology. The Report from the Protozoological Department is not forth- coming as the head of the Department, Dr. J. Gordon Thomson, is now on a research expedition in Rhodesia in regard to blackwater fever and malaria.

I trust that it will interest you to know that the work of the School progresses satisfactorily. The sessions have been largely attended and at the present time sixty students are taking out the course.

up

Dr. F. W. O'Connor has returned from Samoa and is. now engaged in writing his report.

Negotiations are now taking place with the New Zealand Govern- ment for Dr. John Anderson to proceed to Samoa to carry on the work commenced by Dr. O'Connor in connexion with filariasis and kindred diseases.

The School mourns the loss of its great leader, Sir Patrick Manson, who was not only one of its founders, but who devoted himself to its well-being until the end.

I am, &c.,

SIR,

Enclosure 1 in No. 6.

Secretary.

REPORT OF THE DIRECTOR OF THE DEPARtment of MEDICAL ENTOMOLOGY, LONDON SCHOOL OF TROPICAL MEDICINE,

I HAVE the honour to submit the following Report on the Department of Medical Entomology and General Medical Zoology for the half-year ending 30th April, 1922.

* No. 27 in Miscellaneous No. 321.

During the half-year two courses of lectures and practical work in the laboratory have been conducted in Medical Entomology and two short courses of lectures on venomous snakes and snake-venoms. The first courses, in the autumn session, were attended by sixty-two students; the second, in the winter session, by sixty-four.

In the autumn session one student did a special course of study on the Culicidæ, and in the winter session one student did a special course on the morphology and classification of insects and on the intestinal parasites of insects.

The half-year just concluded is not an auspicious time for laboratory work on living insects. Numbers of Stegomyie fasciate were bred under ordinary house

conditions to see whether under such conditions these insects could survive the winter. Starting with a generation hatched from eggs received from West Africa at the end of September, we managed to reach the third generation of adults; but this third generation of adults were much disinclined to feed, and though some of them fed freely they did not produce eggs, and all gradually died off during a spell of cold weather in March. These experiments are, perhaps, of no very great import- ance, but they seemed to me worth pursuing in view of the fact that an entomologist of repute has stated that he bred two specimens of Stegomyie fasciate from water taken out of a hole in a tree in Epping Forest.

Medical Officers of Health in this country frequently refer matters out of their ordinary experience to this School. During the half-year this Department of the School has answered several such inquiries and has identified insects found in unnecessarily disquieting circumstances.

Some magnificent material has been presented to the Department for its teaching purposes. Most particularly to be mentioned is the series of Chrysops infected with Filaria Loa presented by our old students Dr. and Mrs. A. Connal, of Lagos. These show all stages of the parasite, from the end of the first day after feeding on an infected man up to the passage of the larval worm from the fly's proboscis. One magnificent specimen shews the worms wriggling out of the fly's proboscis. Not less desirable is the series of Stegomyie pseudoscutellaris infected with Filaria bancrofti brought back by Dr. F. W. O'Connor from the Pacific Islands, and of Finlaya Rochi shewing aborted infection of the same parasite.

Of other material presented, the following requires mention:- From Mr. Clifford Dobell, F.R.S., the original drawings of Intestinal Protoza illustrating his book on the subject: these have been mounted and hung in the Museum.

From Dr. S. H. Daukes; two very fine specimens of the Indian Cobra; exhibited in the Museum.

From Mrs. Jordan, through Dr. A. Castellani; a useful Index collection of Diptera.

From Lt.-Colonel W. P. MacArthur, D.S.O., insects of sanitary importance. From Dr. Alfred Moore; a large collection of insects, illustrating a new method of mounting for demonstration purposes.

From Col. W. S. Sharpe; Trombidud Larve infesting ears of rabbits. The following material has been received from correspondents abroad:- From Africa-Eggs of Stegomyie fasciate and a large collection of biting-flies,

in addition to the series of infected Chrysops, presented by Dr. and Mrs. A. Connal. Specimens of several species of Simulim, presented by Mr. A. W. J. Pomeroy. Insects, ticks, mites, scorpions, etc., collected by the late Dr. G. Strachan, în Nigeria, and presented by Dr. Pitt Payne.

From America:-Specimens of Anopheles quadrimaculatro, presented by Major Tasker of the United States Army Medical Museum.

From Asia :-A collection of Anopheles of Siam, from Dr. M. E. Barnes.

In addition to all these private donations a very particular mention has to be made of the collection of insects made by Dr. G. M. Vevers in British Guiana and presented by the Department of Helminthology; and of the collections made in the Pacific Islands by Dr. F. W. O'Connor.

During the half year I have been most ably assisted, both in the class and in the collection and preparation of material for teaching purposes, by Lt.-Colonel H. J. Walton, I.M.S., an enthusiastic entomologist and zoologist, who also possesses a great and varied experience in all the practical ends of Medicine and Hygiene.

I am, &c.,

A. ALCOCK, Lieutenant-Colonel, I.M.S.(retired),

Professor of Medical Zoology.
