on circumstances. It is realised that the extermination of Anophelines 

 in any municipal area can only be attained by degrees in conjunction 

 with other forms of sanitary progress. The prmciple adopted has been 

 to let the Government deal with breeding places on its own property, 

 and to call on private owners to fill in such places on their own lands. 

 It should be possible to keep the larger towns completely free from 

 mosquitos with a reasonable amount of expenditure. Constant watch 

 will have to be kept agamst the formation of new breeding places, so 

 that appropriate remedial measures may be applied at once. 



An outline is given of the proposed anti-malaria legislation, and it is 

 suggested that the Malaria Commission should be placed with the 

 Governments' sanction on a permanent basis in order to enforce the 

 law.

The possibilities of mosquito extermination on farms and small 

 estates are discussed ; the measures against mosquito larvae that are 

 essential for control are reviewed, and instructions are given for 

 carrying these out as simply as possible.

The theory that the gecko {Tarentola mauritanica) is the reservoir 

 of Oriental sore has frequently been propounded [R.A.E., B, iii, 143, 

 230, etc.]. From investigations made in Tamerza, on the Algerian 

 frontier of Tunisia, only two out of twelve geckos captured were found 

 to be harbouring flagellates (although Tamerza is a focus of Oriental 

 sore) and these were not discernible under the microscope except 

 after culture. The flagellates were Lepto?no7ias, but were morpholo- 

 gically distinct m culture from the Leislimania or the Lejptomonas of 

 the gecko of Tataouine. The first cultures developed very slowly, 

 apparently owing to the scarcity of parasites in the blood. The virus 

 from the infected geckos and cultures of their Leptomonas did not 

 prove virulent for men, monkeys, mice or geckos. 



These facts indicate that the parasite in question is a flagellate the 

 presence of which in the blood is merely accidental. Its habitat is 

 probably in the digestive tract of the gecko. The failure to inoculate 

 the virus or the cultures into man, in spite of six attempts, or into 

 monkeys, does not bear out the theory of the gecko being the natural 

 reservoir of the virus of Oriental sore.
