SIR,-In reply to Circular No. 71 of 1901, I have the honour to forward you a report on the working of the Medical Department in the New Territory during last year.
I have the honour to be,
The Honourable,
THE COLONIAL SECRETARY.
Sir, Your obedient Servant,
J. M. ATKINSON, Principal Civil Medical Officer.
GOVERNMENT CIVIL HOSPITAL, HONGKONG.
There has been a marked diminution in the number of malarial fever cases from the Police Stations in the New Territory during the year 1901.
On comparing the admissions to the Hospital for this class of diseases for the last two years we find that the nine Police Stations to the North of the range of hills bounding Kowloon give the follow- ing figures:-
Average Strength. Malarial Fever
Admiss ons.
POLICE STATIONS.
1900. 1901. 1900. 1901.

In other words the percentage of malarial fever admissions to Hospital from the New Territory dropped from 90% in 1900 to 52.5% in 1901.
This was undoubtedly occasioned to a great extent by the active prophylactic treatment which was commenced on the 1st May, 1901, and continued up to 1st November of that year.
This varied, at those Stations marked *. Prof. KocH's method was used, viz., one gramme of quinine being given daily for two days followed by an interval of five days without any quinine and so on; at those marked a daily dose of three or five grains of quinine was given; whereas at one Station‡, viz., Au Tau grain of arsenic was given twice daily.
The result of this prophylactic treatment is still further shewn by a Table marked A which I attach showing all the cases of malarial fever at the Police Station in the New Territory from March to December, 1900, and 1901, and the prophylactic treatment adopted.
This return includes the cases treated by the Resident Medical Officer in addition to those sent in to Hospital.
From this it will be seen that quinine is the best prophylactic, and of the two methods, if anything, the daily administration of a small dose has been followed by the best results.
Another important factor in this diminution is that the Police were in 1901 housed in permanent
buildings at Sha Tau Kok in 1900 the Police were under canvas.
Recognised precautions were more fully taken against malaria, the neighbourhood of the Police Stations was kept as free as possible of Anopheles, the Police were instructed how to recognise Anopheles
