The preparation of the Memoir (No. 1.n.s.) entitled "Guide to the Study of Tsetse Flies," to which attention was drawn in a previous Report (Tropical Diseases, 4,008.24) has been completed (see list of publications) and is now on sale at the offices of the University Press, Liverpool.

British Empire Exhibition.-An additional collection of exhibits from this school was placed on view at Wembley, for the Civic Authorities of Liverpool, during the month of September. The diseases illustrated were:-

(1) Leprosy.

(2) Elephantiasis.

(3) Guinea worm.

(4) Plague.

(5) Publications illustrative of the scientific achievements of the School from

the date of its foundation to the present day.

Identification of bloodsucking insects.-About 1,000 specimens of mosquitoes, 150 specimens of tabanids and 1,000 specimens of tsetse flies have been determined for various authorities and institutions. The collections came chiefly from the Belgian Congo, Sierra Leone, Jamaica and Venezuela.

Adler, S.-A note on Plasmodium agama (Wenyon, 1908). Ann. Trop. Med. and

Parasit. Vol. XVIII., No. 2, p. 131. Blacklock, B.-Larvae of the Tumbu Ay, Cordylobia anthropophaga in the lower eyelid. Ann. Trop. Med. and Parasit. Vol. XVIII., No. 2 Miscellaneous, p. 239.

Blacklock, B.-Craw-Craw in Sierra Leone. Ann. Trop. Med. and Parasit.

Vol. XVIII., No. 3, p. 253. The disease called Craw-Craw in Sierra Leone is identical with scabies. When the eruption is generalized and of recent origin it sometimes corresponds to the condition described by Kennan as acute Craw-Craw. The parasite which gives rise to it is identical morphologically with Sarcoptes scabei.

The parasite is frequently very difficult to discover in the black skin. From long persistence in an untreated condition the disease often causes severe lesions in the skin.

Ann. Trop. Med. and Parsit. Vol. XVIII., No. 2, p. 135. Owing to the smallness of the numbers of West African ship-rats examined here and in Liverpool, it is not yet possible to say whether Xenopsylla brasiliensis is capable of remaining alive during transport on ships to England.

Whether X. brasiliensis is a plague-transmitting flea or not, it appears probable from our figures that there is a sufficiently large percentage of X. cheopis present on rats in Freetown to carry plague effectually in epidemic form, should this disease be imported.

Blacklock, B. and Thompson, M. G.-Human Schistosomiasis due to S. hæmatobium

in Sierra Leone. Ann. Trop. Med. and Parasit. Vol. XVIII., No. 2, p. 211. During an investigation into the prevalence of Schistosomiasis in certain districts of the Protectorate of Sierra Leone, infection due to S. hæma- tobium was the only type of the disease found.

Physopsis cf. globosa, Morelet, was proved to be the intermediate host; the infection rate in the mollusc with cercaria of S. hæmatobium was often very high, e.g., 42 per cent. in a water latrine.

A description is given of the morphology of the cercaria of S. hæmatobium, it differs markedly from the description of this cercaria at present accepted.

A critical analysis of the basis of the existing description is undertaken. Some facts relating to the bionomics of Physopsis c.f. globosa are mentioned; experiments showed that this snail was resistant to drying to an unexpected degree.

Of snails placed on mud in the shade a large percentage survived for a fortnight when the water was drained away gradually.

A report on the subject has been submitted to the Government of Sierra Leone, and will be published in the Annual Medical and Sanitary Report of the Colony.

Gordon, R. M.-The value of Urinary Examinations in the Diagnosis of Malaria.

Ann. Trop. Med. and Parasit. Vol. XVIII., No. 3, p. 351.

The work which follows was undertaken with the object of ascertaining whether the more commonly employed urinary tests and examinations have any value as aids in the diagnosis of malaria.

As regards positive findings, it can at once be stated that no individual test was found to have any real value as an aid in the diagnosis of malaria.

so far, therefore, as any single 'test is concerned the results obtained are in accordance with the views expressed by Lane (1923).

As regards negative findings, the absence of urobilin from the urine of a suspected malaria case appears to be of very considerable value, for not less than 87 per cent. of all true cases of malaria, whether examined in England or West Africa, showed the presence of urobilin and it has been shown that urobilin is sometimes a precursor of the malaria parasites and usually persists after the latter's disappearance. It is, therefore, probably legitimate to consider that a case which has had a rise of temperature within the past forty-eight hours and does not exhibit urobilin in the urine is extremely unlikely to be suffering from malaria.
