THE LONDON SCHOOL OF TROPICAL MEDICINE to COLONIAL OFFICE.

SIR,

(Received 24th November, 1917.)

London School of Tropical Medicine (University of London),

Royal Albert Dock, E.. 23rd November, 1917.

I HAVE the honour to submit herewith Reports of the Entomologist, Colonel A. Alcock, I.M.S., C.L.E., F.R.S., for the half-years November, 1916, to April, 1917, and from May to October, 1917. I also enclose the Reports of the Helminthologist, Dr. R. T. Leiper, for the same periods.

The Protozoologist, Dr. J. Gordon Thomson, is still in Egypt, and therefore there is no report from his Department.

The number of students attending the School during the academic year, 1916, to July, 1917, was small, only twenty-one in all, but the continuity of the instruction was maintained and the curriculum was carried out in its entirety.

I enclose a copy of the School accounts,* which show that there is a surplus on the income and expenditure account for the year 1916.

From the foregoing it will be observed that the work in the Special Departments, with the exception of Protozoology, has been continued as heretofore, and the Board The of Education has continued in full its annual contribution to the School. Committee trust that the Tropical Diseases Research Fund Committee may see its way to renew the grant in the interests of entomology and helminthology.

I am, &c.,

P. MICHELLI,

Secretary. P.S.-A new prospectus has lately been issued, and I forward three copies of this under another cover.

REPORT OF THE ENTOMOLOGIST FOR THE HALF-YEAR ENDING 30TH APRIL, 1917.

DURING the period of report I have, in addition to my ordinary duties, carried on the teaching work of the Protozoology Department; and, in addition to conducting the autumn and winter courses of medical entomology and snake toxicology, I have given corresponding courses of instruction in protozoology, and have made a considerable series of microscopical preparations for the permanent study collection in the same subject. The permanent study series of entomological preparations has also been considerably increased.

All the rest of my time has been very fully occupied with the development of the new School Museum of Tropical Medicine and Pathology.

Assistance has been given to correspondents in several parts of the world, and various samples of imported produce infected by insects have been examined for the Health Officer of the Port of London. In one case the insects damaging a con- signment of figs were found themselves to be infected with a myxosporidian parasite a very interesting and decidedly suggestive observation from several points

of view.

The additions to the departmental collections have, naturally, been few. From Dr. T. R. Beale Browne, some African Tabanidæ; from Dr. C. W. Daniels, larvæ of the biscuit weevil passed by a patient; from Dr. A. Graham, through Dr. Daniels, larvæ of a Muscid fly passed by a patient in China; from the Imperial Bureau of Entomology some dipterous and hymenopterous parasites of the pupa of Glossina morsitans; from Dr. W. B. Johnson, Northern Nigeria, further specimens of venomous snakes and blood-sucking flies, some very fine specimens of Poroce- phalus, and another good series of blood-films of animals infected with various hæmosporidian parasites; from Dr. Dyce Sharpe, African beetles; from Dr. W. G. Watt, Coomassie, several consignments of larve of the local house-haunting mosquitoes, culicine and anopheline; from Dr. F. E. Whitehead, Somaliland, å collection of ticks and insects, along with much interesting information regarding their reputation in native pathology and their vernacular names.

All the collections in my charge are in good order, nothing having been damaged by the Silvertown explosion in January, although several windows were blown to pieces and much ceiling-plaster fell in the entomology workroom, and the glass shades of the microscopes were destroyed.

Throughout the period of report I have been assisted by Dr. R. P. Cockin.

REPORT OF THE ENTOMOLOGIST FOR THE HALF-YEAR ENDING 31ST OCTOBER, 1917.

In the summer session I conducted the ordinary systematic classes in protozoology, entomology, and snake toxicology. Two excursions were made with the entomology class to study the natural environment of mosquito larvæ, particularly the breeding places of Anopheles maculipennis.

Many permanent preparations of parasitic protozoa have been made for the reserve and study collection in this subject.

Inquiries have been answered, and specimens identified, for numerous corres- pondents abroad and also in England.

All available time has been devoted to the new Museum of Tropical Medicine. which is developing nicely, all the specimens illustrating tropical pathology, and all the exhibits of venomous snakes being now in position in their respective cases. In addition to much miscellaneous stuff the following select material has been received:

From Surgeon H. M. Hanschell, R.N., D.S.C., a remarkably fine specimen of the venomous snake Boulengerina stormsi with young, from Nyasaland.

From the Indian Zoological Survey Department, specimens of several species of freshwater crabs that act as intermediate hosts of a developmental stage of a fluke- worm parasite in man.

From Dr. J. E. L. Johnston, Northern Nigeria, some venomous snakes and scorpions and some blood-smears of snakes infected with hæmocystidium.

From Dr. W. B. Johnson, Northern Nigeria, a copious collection of blood- smears of reptiles and birds infected with hæmosporidia of several species.

From Dr. I. Pollard, Northern Nigeria, some stinging hymenoptera. From Dr. C. Strickland, Federated Malay States, a good series of Malayan anopheles and some other specimens of diptera.

From Dr. G. W. Watt, Gold Coast, mosquito larvæ of several kinds and living eggs of Stegomyia fasciata.

From Dr. F. E. Whitehead, Somaliland, some ticks and some eggs of the floor maggot fly (Auchmeromyia luteola).

REPORT OF THE HELMINTHOLOGIST FOR THE HALF-YEAR ENDING 30TH APRIL, 1917.

SIR,

103, Corringham Road,

Golders Green, N.W., 28th April, 1917. I HAVE the honour to submit my half-yearly report as Helminthologist to the London School of Tropical Medicine.

In submission to the instructions of the School Committee my preoccupations during the period have been wholly concerned with the routine of my Department and with the furbishing of the helminthological section of the School Museum. The specimens in the "helminthiasis" part of the Museum have now been rebottled, and steps are being taken to label them in accordance with the current teaching.
