4. A letter from Sir W. M. Fletcher was laid before the Committee regarding the representation of the Medical Research Council on the Committee.

It was agreed to ask the Medical Research Council to nominate a member to serve on the Committee.

5. The Chairman suggested that Dr. A. E. Horn should be appointed a member of the Committee. This was agreed to.

6. The Committee discussed various papers which had been circulated to them by the Colonial Office on the use of chaulmoogra oil. The Chairman observed that, in view of the formation of the British Empire Leprosy Relief Association, the Colonies concerned had been informed that it was now no longer necessary for the special reports to be furnished unless any case of unusual interest occurred, or any new development in this method of treatment was tried and found to be successful

THE LONDON SCHOOL OF TROPICAL MEDICINE to COLONIAL OFFICE..

(Received 23rd May, 1924.)

SIR,

Seamen's Hospital, Greenwich, 21st May, 1924. AGAIN I have the pleasure to send you the half-yearly reports of the Special Departments at the London School of Tropical Medicine for which a grant is received from the Tropical Diseases Research Fund. While doing so you may permit me to refer to the approaching transfer of the School from the Seamen's Hospital Society to the London School of Hygiene and Tropical Medicine.

It is possible that this may be the last occasion upon which I shall have the honour to transmit these reports, and in doing so I beg you may permit me to say that my Committee haye every confidence in the wisdom of the change, and feel assured that success will attend the course of study in tropical medicine which will be carried on under the new administration.

I am, &c.,

P. J. MICHELLI,

Secretary.

P.S.-Under separate cover the following publications of the School have been forwarded to you :---

Journal of Helminthology, Vol. I, No. 5. Journal of Helminthology, Vol. II, No. 1. Journal of Helminthology, Vol. II, No. 2.

REPORT ON THE Department of MEDICAL ENTOMOLOGY, LONDON SCHOOL OF TROPICAL MEDICINE, FOR THE HALF-YEAR ENDING 30TH APRIL, 1924.

DURING the half-year two courses of lectures, demonstrations, and practical work in the laboratory were conducted in medical entomology, and two courses of lectures and demonstrations on snakes and their specific venoms. The total number of students attending the courses was over 100.

There were no advanced or special classes, but Mrs. H. A. Adie was given accommodation prior to her departure for Algeria and the Pasteur Institute there.

Many identifications have been made and professional inquiries answered for correspondents abroad, the majority of whom are old friends and students of the School.

The study collections and the preparations exhibited in the general Museum have been added to, and the reserve collections have been considerably increased, as is shown in the sequel.

Collections of living Anopheles were brought from Romney Marsh in October to ascertain whether these insects could be got to feed and produce eggs in the

63

laboratory during the winter in London, as they have been induced to do in a laboratory situated in the country; but the attempt was not successful here in London they could not be got to feed either on human beings or on rabbits. On the other hand, Stegomyia fasciata will feed and produce good eggs, and the larvæ can be reared, in the winter, in an ordinary room of the (centrally heated) School building.

The following additions have been made to the reserve collections:- 1. African material from-Mrs. H. A. Adie, web specimens of Lynchia maura showing oocysts in the stomach wall-as long ago discovered by Mrs. Adie, though for some unaccountable errors in technique not unanimously confirmed by others. Mrs. Adie, working in the Pasteur Institute of Algiers by the courtesy of M. E. Sergent, has recently confirmed her discovery.

Mrs. H. A. Adie-specimens of Sarcoptid mites parasitic on Lynchia maura, and among them the hitherto unknown male of the remarkable Myialges anchora.

Dr. J. Bancroft Anderson-specimens of Stegomyia fasciata and S. simpsoni from East London.

Dr. J. O. Bevan-a fine collection of venomous snakes, and other material from East Africa.

Dr. and Mrs. A. Connal-relays of fertile eggs of Stegomyia fasciate.

Mr. R. H. Harris-a large stock of Glossina morsitans for class use, from South Africa.

Dr. LI. Lloyd-a large stock of Glossina tacginoides and E. palpalis for class use, from Nigeria.

Dr. A. G. Neale-a specimen of Simocephalus puens infected with Porocephalus subulifer from Nigeria.

Dr. R. S. Taylor-reptiles of ill repute from British Somaliland.

2. American material. Dr. A. Balfour, C.B., C.M.G.-specimens of Diptera and of Fundulus bermudensis, from Bermuda.

Dr. S. H. Daukes-specimens of small fishes (mollienisia latipinna and Cichlosoma sp.) used in tropical America for destroying larvæ of Stegomyia fasciate. Dr. H. B. Newham-Mosquitoes and Tabanidæ collected by friends in British Honduras.

Dr. K. S. Wise-specimens of Phlebotomus trinidadensis and Culicoides maculithorax, from Trinidad.

3. Asian material.-The late Major F. W. Cragg, I.M.S.-a large collection of named Indian rat-fleas; also preserved venom glands of the Indian Cobra, for class use.

Lt. Col. C. A. Gill, T.M.S.,-salivary glands of Culex infected with sporozoites of Proteosoma.

Capt. J. M. R. Hennessy, I.M.S.-venomous snakes and scorpions.

Lt. Col. F. P. Mackie, I.M.S.-preserved venom glands of Russell's viper, for class use.

Dr. J. W. Scharff-larvæ of Anopheles from Malaya.

Mrs. le Sueur (Miss O'Driscoll)-venomous snakes and scorpions from North Borneo.

Throughout the half-year the Department has been administered by myself with Lt.-Colonel H. J. Walton, M.D.. I.M.S., as assistant. In the autumn term we had the temporary assistance of Major T. L. Bomford, M.D., I.M.S., and in the winter term of Dr. H. T. Wiltshire as class demonstrators.

For help in the identification of unfamiliar species I have been indebted, as in many years past, to various departments of the British Museum of Natural History and to the kindly attentions of the officers in charge of them; and for material for class use I have to record our due acknowledgments to the Imperial Bureau of Entomology and Dr. Guy Marshall, F.RS.
