I beg to submit the following report for the period 1st November, 1923, to 30th April, 1924.

Tuition.

The number of students attending the course of, instruction for the Diploma in Tropical Medicine during the Lent Term was eight, and twelve Veterinary students attended the special courses in Veterinary Parasitology and Entomology. Mr. Stewart Ross Rippon, M.R.C.V.S., attended a special short course of Veterinary Parasitology from 1st November, 1923, to 14th December, 1923.

Research.

Details of the investigations undertaken during this period will be found under Publications.

The subjects of research included :---

(1) The morphology and bionomics of Cordylobia anthropophaga, Grünberg,

with special reference to its connexion with cutaneous Myiasis.

(2) A new species of Phlebotomus from Japan.

(3) The regulation of the species Glossina ziemanni' to a synonym of Glossina

palpalis, sub-species fuscipes, Newstead.

(4) Malignant growths in natives of Sierra Leone.

(5) The frequency of Indicanuria.

A further investigation into the malaria parasite of a Chimpanzee.

(7) Some peculiar forms of Plasmodium falciparum.

(8) On the so-called pearl-inducing worm in the Ceylon Pearl Oyster.

(9) On the relative numbers of male and female crescents in malaria.

(10) A new Isospora of Civet Cats.

(11) Ascaris lumbricoides, causing fatal lesions in a Chimpanzee.

(12) The action of the salivary secretion of mosquitoes, and of G. tachinoides,

on human blood.

(13) The transmission of Trypanosoma evanei by Ornithodorus crossi.

(14) The duration of infection in a case of malaria.

(15) The urine in malaria.

Entomology Department.

The most important work undertaken by this department has been the preparation of a monograph, entitled "A Guide to the Study of Tsetse Flies," which will shortly appear. This necessitated investigation into their morphology, and an extensive study of the very large number of publications dealing with this important group of insects. The book is designed especially for the use of Medical investigators in Tropical Africa, to whom it will, we trust, prove of considerable

value.

A considerable amount of speciographic work has been done, including the determination of extensive collections of mosquitoes from the Belgian Congo, Venezuela, the River Amazon and New South Wales; of tsetse flies from the Bahr-el-Ghazel, in the South of the Anglo-Egyptian Sudan, and from various parts of the Belgian Congo; and of a number of Coccids which were causing a serious loss to various plants under cultivation in Sierra Leone. In the course of this work a species of sand-fly (Phlebotomus), new to science, was described from Japan, and also new species of mosquitoes from the Belgian Congo and from Venezuela.

Adler, S. An Isospora of Civet Cats. Ann. Trop. Med. & Parasit. Vol. XVIII, No. 1, p. 87. An Isospora was studied in three heavily infected civet cats. The asexual and sexual cycles within the host are described. Oocysts containing two sporoblasts were found in the intestine and in fresh fæces.. The oocysts measured 19 to 27.5, in length by 15.2. to 24.7 in breadth. The development of the oocysts outside the body of the host is described. Cats and dogs fed on heavily infected material failed to become infected within an observation period of twenty-eight days. The name Isospora viverræ, n. sp., is proposed for the Isospora of civet cats.

The morphology and bionomics of Cordylobia anthropophaga, Grünberg, have been studied in some detail during the dry season, 1922-23, in Freetown, Sierra Leone. Certain new facts as regards the habits of the adult are recorded. In the first larval stage, attention is drawn to certain morphological pecu- liarities which appear to have a direct and intimate connexion with the process of skin penetration. Evidence is produced which appears
