King's College for Women, but is continuing the work on which she was engaged with a view to the M.Sc. degree.

The research work on which this investigator was engaged was carried out in conjunction with Dr. Andrew Robertson, Grocers' Research Scholar, and was mainly concerned with members of the family Trypanosomida. The changes in the morphology and virulence of various strains of Trypanosomæ gambiense were care- fully studied. A considerable amount of work was done on the pathology, morphology, and life cycle of Trypanosoma cruzi. Attempts were made to infect certain ectoparasitic insects of man with this trypanosome in order to ascertain whether they could act as vectors. The most significant result obtained was in the bed bug Cimez lectularius, the infection probably being retained throughout the insect's life. A young rat inoculated with the metacyclic forms of the trypanosome panosome from the dejecta of a bug which had had an infected feed six months previously, developed the disease.

Dr. Robertson in conjunction with. Dr. H. B. Newham, C.M.G., studied a case of human coccidiosis. This was of interest, firstly, because the cocysts of Isospora hominia were found in the stool in London and, secondly, because the infection was probably acquired in Durban, South Africa.

Since the last report was made the following papers have been published :— (1) Charcot-Leyden Crystals in the Stools as an Aid to the Diagnosis of

Entamoebic Dysentery. By J. G. Thomson and A. Robertson. Jour. Trop. Med. & Hygiene. 15th November, 1921.

(2) Eimeria oxyspora. Dobell, 1919, found in a Specimen of Human Greces in

England.

(3) Embadomonas intestinalis (Wenyon and O'Connor), 1917. Description of the Cysts and Free Forms Found in a Case in England. By W. Broughton Alcock and J. G. Thomson. Proceed. Roy. Soc. Med. 1922, Vol. XV (Section of Trop. Diseases and Paras.)

(4) A Case of Isospora hominis (Rivolta), Dobell, probably contracted in Durban, South Africa. By H. B. Newham, C.M.G., and Andrew Robertson. Jour. Trop. Med, & Hygiene. 1st November, 1922.

Staff-The following new appointments have been made:-

Assistant Lecturer on Entomology.

W. H. Potts, B.A.

Lecturer on Tropical Surgery.

Robert Ernest Kelly, C.B., M.D., F.R.C.S.

Research.-Details of investigations undertaken during this period will be found under Publications. The various lines of research include:-

An inquiry into the distribution of ancylostomes in domestic animals both in Sierra Leone and Brazil. In the case of Brazil an investigation was also made of

the distribution of these parasites in the human host.

Study and description of Culicido collected in Venezuela and Amazonės. Study and description of both Indian and Australian Cestodes.

An investigation into the value of the signs of filarial disease as seen in West Africa.

An inquiry into the pathological effects produced by certain nematodes in the chimpanzee, and also in dogs in West Africa.

An experimental study of the susceptibility of the new-comer to the bites of the yellow fever mosquito in Brazil.

Two pieces of critical work were also undertaken, one being a review of recent work on the pathology of blackwater fever, and the other an examination of the value of figures purporting to show the incidence of a disease in population groups.
