Ships' Disinfection.-As the use of Hydrocyanic Gas is coming into favour for the disinfection of vessels, the Liverpool Port Sanitary Authority has made arrange- ments for an investigation to be carried out, jointly with the City Analyst, to ascertain precisely what effect the gas has on various kinds of insects together with their eggs and larvæ. The results of this investigation will be embodied in a later report.
Much time has been devoted to the preparation of an extensive monograph which it is hoped may be completed towards the end of the year.
Collections of mosquitoes and other blood-sucking Arthropods numbering over 700 specimens have been sent to us for determination. These came from the follow- ing countries: Africa (chiefly the Congo Free State), South America and China.
The following investigators have been given facilities and free tables for study and research :-

Malaria." The investigation on the malaria parasite discovered in a chim- panzee has been continued so far as was possible with the funds available. My colleague Dr. Adler proceeded up country on the 23rd of August in order to examine as many chimpanzees as possible and also to bring back to the Laboratory such infected animals as could be purchased so that the mosquito or other vector which conveys the disease might be sought by experimental feeding. His findings proved of great interest and are now in the course of publication. He was successful in discovering several chimpanzees infected with what we have stated to be a parasite identical with the human parasite. Further, he was able to form the opinion that the infection is common among young chimpanzees, but that in older animals it has died out or become so mild as to be difficult of recognition. In this respect it is comparable to the infection as found among the natives of the country, a fact which may prove of value in bringing it still further into line with the human parasites.
Of several chimpanzees which he was able to bring down to Freetown, two contained parasites in the crescent form, but unfortunately the numbers of the crescents were small, and it was not found possible to carry out experiments with mosquitoes before the crescents had fallen to such low numbers as to render success improbable. This is a piece of valuable research which remains to be done in the future and which only awaits funds for its pursuit.
Acute ascending paralysis.—One of the chimpanzees immediately after being captured developed signs and symptoms of a condition of paralysis known in man as acute ascending paralysis. Observations were made of the condition and a paper on the subject has been prepared by Drs. Adler and Clark. The condition is a rare one in man, and so far as I am aware has never before been known to develop in the chimpanzee. The chief interest lies in the fact that the condition arose in a wild chimpanzee just after capture, although there was no evidence of injury during capture, nor was it attributable to dietetic causes after its capture.
Other facts of importance concerning the diseases to which the chimpanzee is liable in nature and in captivity have been collected and will be published."
Helminthiasis. Further study of the helminth infection of man and animals has been made and has yielded results of some value. It is clear, however, that so long as it remains impossible to carry out examination on those who die in infancy and early childhood only indirect evidence from animal examination can be obtained. From this side considerable progress has been made.
Tsetse Fly-I mentioned in the previous report that it was proposed to investi- gate the fly on the Cape Lighthouse Peninsula. During July and August I visited this place and made dissection of 471 flies. The examination proved that the fly was present in numbers, and that it was still infected to the extent of 5 per cent. with trypanosomes. This being so it is now proposed to make a drastic clearing of the breeding places and try not only to eradicate the fly. but also to prevent its re-establishing itself. The means proposed are, after clearing, to plant suitable crons which will not afford the shelter necessary to the fly for breeding. Should
