supported on a four-legged iron stand, so that the pan itself is 3 inches to 4 inches from the ground.

A little alcohol is added to assist the sulphur in com- mencing to burn. One or more of these pans is placed in each room or compartment and also between the ceiling and roof.

No accident has yet resulted as a consequence of using this method.

After the sulphur is fired and every opening stopped up, the place is left closed for 1 hour, if sulphur be used, and 3 hours if pyrethrum. In a properly sealed up place sulphur is burnt in the proportion of 20 grammes per cubic metre and pyrethrum in half that quantity. In a place which cannot be properly sealed up sulphur is used in the propor tion of 30 grammes per cubic metre.

After the process is completed the men go back, clean up, and put things in order again.

The owners or occupiers are requested, when all is sign a paper stating whether any damage has been done, over, to and if so its value.

Reparation is made by the Authorities for any articles injured or broken, &c.

I was fortunate in being able to observe the process of fumigation in several houses.

14. Water Containers.—All cisterns and water containers have to be screened at the expense of the owners, and to the satisfaction of the authorities, and to each cistern is attached a certificate showing when the screening was done and who certified to its efficiency.

15. Larvicide.-As a larvicide kerosine is used, and is often mixed with 5 per cent, of creolin.

16. Administration.-The staff employed consists of :-

Dr. Pedroso.

16 medical officers.

3 inspectors to attend to cleaning up and mosquito- breeding places, having 120 men under their direction.

3 inspectore, who attend to fumigation, with 90 assistants. In addition there are the necessary clerks, storekeepers,

chauffeurs, cartmen, &c.

There is a central office in the town and a store, with stables, &c., attached, nearer the outskirts.

Motor cars are used to increase the facilities for getting about.

Carts and ambulance carriages, with horses or mules, for the transport of patients and the necessary material are also provided.

All tools and materials which may be required in any part of the work are kept in a large store and issued when required on a requisition signed by a medical officer.

17. Cost-The cost of the work per month is between £9,000 and £10,000, but the result is already beginning to show its justification.

Considering the cost of things in general, the usual scale of salaries and wages, and that the whole staff has been brought up from Rio, this is not really so large as

sum,

which may appear excessive, it appears.

Manaos.

18. Men Employed. The anti-yellow fever work is done here under the direction of the Town Health Officer by a gang of 70 men, who, I understand, are said to work from 1.30 to 4.30 daily, which includes time occupied in changing in and out of uniform.

19. Fumigation.-Fumigation is done occasionally, but at the time of my visit, although sadly needed, there was no material to do it with.

20. Work already done.-Dr. Thomas informs me that a good deal of cleaning up and some reclamation has been done although many of his recommendations have not yet been carried out, and also that in a very large percentage of the compounds mosquito larvæ can be found.

21. Water Supply.-The water supply is intermittent and cisterns and other water containers have to be used, but screening of them is not properly enforced.

22. Yellow Fever Hospital Wards. In one of the hospitals there are yellow fever wards (for males only) which
