difficult to carry out in the thorough way necessary for success, 

 but notwithstanding these difficulties it cannot be too strongly 

 emphasised that arrangements for the treatment by quinine of 

 those sick from malaria is a matter of primary importance from 

 the point of view of saving life, of preventing suffering, and of 

 destroying a potent source of infection. On the other hand ex- 

 perience in the United Provinces and elsewhere has shown that 

 the regular administration of quinine to school-children during 

 the malarial season is a practical measure of proved utility and 

 easy application. 



(3) In view of the correlation which certain observers have 

 found to exist between density of jungle in and around villages 

 on the one hand and intensity of malaria on the other it is 

 desirable that this question should receive the careful attention 

 of all those working at malaria in India. 



(4) In view of the fact that investigation has shown that the 

 cultivation of rice and other crops, for which an abundance of 

 water is necessary during growth, need not lead to the forma- 

 tion of dangerous breeding grounds for mosquitos, it is desirable 

 in the interests of the Indian agriculturist to ascertain definitely 

 the precise conditions under which such cultivation is or is not 

 likely to be harmful. 



(5) Further research is necessary with a view to ascertaining 

 the most effective larvaecides and natural enemies of the mos- 

 quito, and which of them are best suited for use in particular 

 localities and under different conditions of environment. It is 

 desirable, moreover, to consider the advisability of constructing 

 ponds in centres where permanent water can be obtained for 

 the breeding on a large scale and the distribution of the more 

 important of the natural enemies of mosquito larvae. 



Other resolutions deal with such subjects as educational 

 propaganda, borrow-pits, water-tidiness, and the provision of a 

 pure and protected water supply. But it must not be imagined 

 that the functions of the General Malarial Committee begin and 

 end in the passing of pious resolutions at conferences. On 

 the contrary it is doing much practical work, and its organisa- 

 tion has been materially strengthened by the appointment of 

 special malarial officers in Madras, Bengal, the United Provinces, 

 the Central Provinces, the Punjab and Burmah. A Central 

 Malarial Bureau, consisting of a museum, a laboratory, and a 

 reference library, under the charge of Major Christophers, has
